S. pooja.gk24@gmail.com Lakshmana D. pooja.gk24@gmail.com Sharanabasappa pooja.gk24@gmail.com <p>The evaluation of morphological and yield traits of tamarind genotypes was carried out during 2017-18 at Forest Research Station, Govinkovi, Honnali taluk, Davangere district. The experiment was laid out in randomized complete block design with 16 genotypes and three replications. Trees were 14-years-old and of grafted origin. All the morphological and yield traits showed significant difference among the selected genotypes indicating the presence of adequate variations. The genotypes recorded morphological variation in terms of tree shape (semi-circle to irregular shape), foliage arrangement (dense to sparse), flowering time (early, mid and late), stem colour (dark brown, brown and light brown), bud colour (greenish white, pink, dark pink), petal colour (yellow and pale yellow), pod colour (greyish brown, brown, light brown and dark brown), pulp colour (light brown, brown and reddish brown), pod shape (straight, slightly curved, curved and deeply curved) and pod size (very big, big, medium and small). The analysis of variance revealed significant difference with respect to tree height, stem girth, pod traits, pod yield per tree (K-9 : 12.80 kg), number of pods per tree (NTI-52 : 989.07) and pulp per cent (K-9 : 48.87). Among the 16 genotypes, the genotype K-9 was found superior with respect to pod size, pod weight, pulp weight and pod yield per tree. Genotype K-9 was found promising and due to perennial in nature further evaluation is required for stability.</p> 2022-12-31T00:00:00+0530 Copyright (c) 2022 POOJA G K, Nagarajappa Adivappar, Shivakumar B.

Less than 1% of the produce is processed when compared to 26% in other major producing countries. Of the estimated more than 41 million tonnes of tomato processed globally, only 130,000 tonnes were processed in India and domestic demand for processed tomato products is expanding at an estimated 30% annually. At present traditional fresh market tomato cultivars are being processed though such cultivars are unsuitable for processing. Processors in India are looking for high yielding tomato cultivars with high total soluble solids (5-6 º Brix), acidity not less than 0.4%, pH less than 4.5 and uniform red colour with a/b colour value of at least 2. In addition, firm fruited tomato cultivars with joint less pedicel (j2) which facilitate mechanical harvesting or rapid hand picking. ICAR-Indian Institute of Horticultural Research has recently developed two high yielding F1 hybrids in tomato viz: Arka Apeksha and Arka Vishesh suitable for processing. On evaluation for three years, both the hybrids recorded good level of total soluble solids (4.5-5º Brix) and colour value of 2. Further, both the hybrids had high yield potential (80-90 tonnes / hectare) with triple disease resistance to tomato leaf curl disease, bacterial wilt and early blight. Arka Apeksha and Arka Vishesh were also bred with jointless pedicel making them suitable for mechanical harvesting. Our experimental studies on vine storability revealed that all the fruits were intact on plants even 110 days after transplanting in the main field facilitating once over harvest.</p> 2022-12-31T00:00:00+0530 Copyright (c) 2022 AVVERAHAALLY SADASHIVA, Oberoi H S, Singh T H , Prasanna H C, Madhavi Reddy K, Krishna Reddy M, Ravishankar K V, Nayana R S https://jhs.iihr.res.in/index.php/jhs/article/view/886 Inheritance studies on different quantitative and qualitative fruit traits in brinjal (Solanum melongena L.) 2021-07-19T19:56:15+0530 Ramandeep Kaur Sidhu ramandeepsidhu624@gmail.com Mohinder Kaur Sidhu mksidhu@pau.edu Ajmer Singh Dhatt ajmerdhatt@pau.edu <p>Generation mean analysis of brinjal lines, GL 401 × BR 104 (CROSS I), GL 401 × W 230 (CROSS II) and W 230 × RMO 1142 (CROSS III) six generation of three crosses viz. highlighted the involvement of epistatic interactions (duplicate) for most of the qualitative traits. However, the number of fruits per plant in CROSS I &amp; III and fruit girth, calyx length, and yield per plant in CROSS II confirmed the occurrence of complementary epistasis. Mainly, additive effect for fruit girth, non-additive effect for calyx length, calyx width, peduncle girth, fruit weight, and fruit length, and both types for peduncle length, number of fruits /cluster, number of fruits/ plant, and yield/ plant were experienced. Additive × dominance or dominance × dominance type of interactions were more prevalent than additive × additive type of interactions for different traits. Cluster bearing was monogenic dominant and green color of calyx as well as peduncle was dominant over purple with the duplicate type of epistasis. Fruit shape was dgenic with incomplete dominance. Fruit color displayed digenic control in CROSS I &amp; II and tri-genic ratio in CROSS III with incomplete dominance of purple and green pigmentations producing variable color intensity in homozygous or heterozygous conditions.</p> 2022-12-31T00:00:00+0530 Copyright (c) 2022 Ramandeep Kaur Sidhu, Mohinder Kaur Sidhu, Ajmer Singh Dhatt https://jhs.iihr.res.in/index.php/jhs/article/view/1456 Characterization and evaluation of putative mutant populations of polyembryonic mango genotype Nekkare for dwarfing rootstock traits 2023-01-03T15:29:09+0530 Nusrat Perveen nusrat.8oct@gmail.com Dinesh M R drmrdinesh@gmail.com Sankaran M kmsankaran@gmail.com Hima Bindu K Himabindu.K@icar.gov.in Shivashankara K S Shivashankara.KS@icar.gov.in Venugopalan R venugopalan.r@icar.gov.in <p>Availability of dwarfing rootstocks is an important pre-requisite for improving productivity of mango orchards in India as it facilitates high density planting as well as impart uniformity within an orchard. An attempt was made to induce variability in polyembryonic mango genotype Nekkare for dwarfness by treating kernels with different doses of gamma radiation ranging from 15 to 35 Gy. Irradiation created significant variation in plant height, stem girth, number of nodes, inter-nodal length, number of leaves, leaf blade length and leaf blade width. The highest reduction in seedling height along with highest variation was observed at 35 Gy where the seedling height ranged from 11.50 to 33 cm with a mean of 23.12 cm as compared to mean plant height of 44.55 cm in control ranging from 33.50 to 56 cm. Further, the effect of irradiation on stomatal parameters was also investigated and the highest stomatal length and width was recorded at 15 Gy (63.39 μm) and 20 Gy (63.12 μm) respectively while 30 Gy treatment produced maximum stomatal density (13.85 per μm2). Furthermore, the<br>concentration of ABA was found to be highest (429.1 ng/gm) in morphologically dwarf (putative mutant) progenies of Nekkare. The results suggest effectiveness of induced mutation for developing dwarfing rootstocks in mango to be used in high density planting.</p> 2022-12-31T00:00:00+0530 Copyright (c) 2022 Nusrat Perveen, Dinesh M R , Sankaran M, Hima Bindu K, Shivashankara K S, Venugopalan R https://jhs.iihr.res.in/index.php/jhs/article/view/1404 Optimization of factors influencing osmotic dehydration of aonla (Phyllanthus emblica L.) segments in salt solution using response surface methodology 2023-01-03T15:28:45+0530 Sujayasree O.J sujaya.iari2016@gmail.com Tiwari R B rb.tiwari@icar.gov.in Venugopalan R venugopalan.r@icar.gov.in Narayana C K narayana.ck@icar.gov.in Bhuvaneswari S bhuvaneswari.s@icar.gov.in Ranjitha K Ranjitha.K@icar.gov.in Oberoi H S sujaya.iari2016@gmail.com Shamina Azeez shamina.azeez@icar.gov.in Sakthivel T sakthivel.t@icar.gov.in Nayaka V S K karthiknayaka1@gmail.com <p>Optimization of process parameters is a critical requirement in food processing and food product industries for the development of highly acceptable product. Quantification of mass transfer kinetics under different processing conditions is essential step for optimizing the osmotic dehydration process. A Box-Behnken Design (BBD), adopted from response surface methodology (RSM) approach was used for evaluating and quantifying the moisture loss and solids gain kinetics of aonla segments in salt solution during the osmotic dehydration process. The independent variables were fixed at three levels (salt concentration- 2, 4, 6%; process<br>temperature - 45, 50, 55 OC and process time - 60, 120, 180 minutes). The process responses were water loss percentage (WL%) and solids gain percentage (SG%). Validation experiments were conducted at optimum conditions to verify predictions and adequacy of the models. The optimum conditions predicted were 5.02% salt concentration, 54.8 OC temperature and 60.64 minutes process time to attain a desired effect of maximum water loss (6.42%) and minimum solid gain (1.09%) in osmotic dehydration of aonla in salt medium.</p> 2022-11-01T00:00:00+0530 Copyright (c) 2022 Sujayasree O.J, Tiwari R B, Venugopalan R, Narayana C K, Bhuvaneswari S, Ranjitha K, Oberoi H S, Shamina Azeez, Sakthivel T, Nayaka V S K https://jhs.iihr.res.in/index.php/jhs/article/view/1132 Effect of nano and macro iron sprays on growth, flowering, seed and oil yielding attributes in calendula (Calendula officinalis L.) 2023-01-03T15:28:21+0530 Narendra Singh Bhandari narendra.singh33398@gmail.com Srivastava R K nsbhandari@gehu.ac.in Tarakeshwari K R nsbhandari@gehu.ac.in Chand S nsbhandari@gehu.ac.in <p>The investigation was executed with nine treatments viz. nano forms of ferrous sulfide (7, 14, 21, 28 ppm) and macro ferrous sulphate (0.2, 0.4, 0.6, 0.8 per cent) along with control, and were applied as foliar sprays after 30 days of transplanting on two varieties of calendula namely Fiesta Gitana Mix’ and ‘Fiesta Yellow’ during 2018 and 2019. The experiment was laid out in factorial randomized block design with three replications. Application of 0.8 % FeSO4 recorded maximum number of branches (26.75), plant height (29.73 cm), plant spread<br>(45.17 cm), number of leaves (22.63) and seed test weight (15.63 g) and number of flowers per plant (134.04). However, application of 0.2% macro FeSO4 resulted in early bud appearance (50.50 days) and higher flower diameter (8.09 cm). ‘Fiesta Gitana Mix’ outperformed over ‘Fiesta Yellow’ for most of the vegetative and floral characters. The ‘Fiesta Yellow’ variety with oil content (13.97%) had an edge over ‘Fiesta Gitana Mix’.</p> 2022-11-01T00:00:00+0530 Copyright (c) 2022 NARENDRA SINGGH BHANDARI, Srivastava R K , Tarakeshwari K R, Chand S https://jhs.iihr.res.in/index.php/jhs/article/view/1434 Advancing fruiting season in Annona cv.

Seven genotypes collected during survey were characterized for different morphological and biochemical traits. Results showed that average fruit weight was 432.57g/fruit, with juice content 100.11 mL/fruit, vitamin C content 25.79 mg, vitamin A content 1.65 mg, Mean total flavonoids content was 16.75 mg/100 g of fruit juice, total soluble solids 12.040 Brix, antioxidant activity (DPPH) 6.07 %, titratable acidity 1.69 %, total carbohydrates 9.95 %, phenol content 338.38 mg/100 g of leaf was noted among the genotypes tested. The mean anthocyanin content in leaf was 1.20 mg/100 g, tendril 0.90 mg/100 g and petiole 1.69 mg/ 100 g among the genotypes. Seed protein profiling of <em>Passiflora</em> <em>quadrangularis</em> L. with SDS- PAGE showed diverse molecular weights ranging from 11 KD to 163.53 KD. However, monomorphic banding pattern among the protein profiling of giant granadilla was recorded among the selected genotypes. The results of the study show that the collected genotypes are belonged to <em>Passiflora</em> <em>quadrangularis</em> L. and are good source of nutritive value which can be used as source of vegetable.</p> 2022-12-31T00:00:00+0530 Copyright (c) 2022 Kripa Shankar, Singh S R https://jhs.iihr.res.in/index.php/jhs/article/view/1481 Optimization of freeze drying parameters for moringa (Moringa oleifera) flower powder by using response surface methodology and principal component analysis 2023-01-03T15:25:36+0530 Pandidurai G nanalpandi@gmail.com Amutha S nanalpandi@gmail.com Kanchana S nanalpandi@gmail.com Vellaikumar S nanalpandi@gmail.com Prabhakaran K nanalpandi@gmail.com <p><em><span dir="ltr" style="left: 141.6px; top: 447.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(1.0059);" role="presentation">Moringa oleifera</span></em> <span dir="ltr" style="left: 281.593px; top: 447.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(0.996183);" role="presentation">Lam. is an incredible plant because of vital nutrients such as minerals, </span><span dir="ltr" style="left: 141.6px; top: 469.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(0.952356);" role="presentation">vitamins and phytochemicals.

Seedlings were grown in protray using six types of growing media. The highest germination percentage (71.11), plant height (11.05 cm), number of leaves (5.81) and percentage healthy seedlings (89.82) were observed with vermiculite + perlite + vermi- compost (1:1:2) during both the years in brinjal. Similarly in chilli, highest germination percentage (66.33), plant height (9.81 cm), number of leaves (5.62) and percentage healthy seedlings (87.61) were observed with vermiculite + perlite + vermi-compost (1:1:2). There was significantly low incidence of whitefly in brinjal (1.49 whitefly/leaf) and chilli (1.65 whitefly/ leaf) seedling grown in media with vermiculite + perlite + vermi-compost (1:1:2). Hence, vermiculite + perlite + vermi-compost (1:1:2) was found as optimum growth media for growing of chilli and brinjal seedlings. The findings of this study recommend the use of vermiculite + perlite + vermi-compost (1:1:2) as growth media for raising nursery by farmers as it had significant positively effect on plant growth parameters of seedlings that lead to increase production of chilli and brinjal.</p> 2022-12-15T00:00:00+0530 Copyright (c) 2022 Prakash Mahala, Rakesh Kumar Sharma, Manmohanjit Singh https://jhs.iihr.res.in/index.php/jhs/article/view/1105 Tomato late blight yield loss assessment and risk aversion with resistant hybrid 2023-01-03T15:24:51+0530 Sandeep Kumar G M sandeep.gm@icar.gov.in Sriram S Subbaraman.Sriram@icar.gov.in Laxman R H laxman.rh@icar.gov.in Harshita K N Sandeep.gm@icar.gov.in <p><span dir="ltr" style="left: 141.6px; top: 337.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(1.00391);" role="presentation">Late blight (</span><span dir="ltr" style="left: 238px; top: 337.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(0.938995);" role="presentation">Phytophthora infestans</span><span dir="ltr" style="left: 414.8px; top: 337.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(0.941916);" role="presentation">) is one of the devastating diseases of tomato worldwide. </span><span dir="ltr" style="left: 141.6px; top: 359.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(0.987133);" role="presentation">Field trial was carried out in</span> <span dir="ltr" style="left: 367.2px; top: 359.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(1.04215);" role="presentation">Kharif</span> <span dir="ltr" style="left: 422.388px; top: 359.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(0.94822);" role="presentation">2019 and 2020 in Hesaraghatta, Bengaluru, Karnataka, </span><span dir="ltr" style="left: 141.6px; top: 381.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(0.964182);" role="presentation">India, to estimate yield loss due to late blight and to assess extent of protection in resistant </span><span dir="ltr" style="left: 141.6px; top: 403.375px; font-size: 18.3998px; font-family: sans-serif; transform: scaleX(0.967447);" role="presentation">genotype during late blight epiphytotics.

Few bush type cowpea cultivars have been earlier identified as reliable sources of resistance while trailing types are susceptible, but high yielding. Breeding resistant varieties is suggested as the only practical strategy, especially under hot and humid condition. Fifty-yard-long bean genotypes belonging to bush, semi erect and pole types were screened against anthracnose disease through artificial inoculation under pot culture. The present study identified the resistant varieties of vegetable cowpea through artificial inoculation followed by detached leaf assay.

CircRNA profiling helps to understand biological process associated with various abiotic and biotic stresses. In tomato genotype IIHR- 2611 (resistant to ToLCBaV), a total of 193 CircRNAs were discovered, of which 72 and 121 were found in control (RC) and ToLCBaV inoculated (RI) plants respectively. Among them, 103 (53 %) were exonic CircRNA regulating the expressions of their parent genes. Relative expression of CircRNAs 2:45295638|45295796, 2:51520741|51530067 and 7:67566489|67566691 and their respective parent genes <em>Solyc02g080530.3</em> (peroxidase), <em>Solyc02g088950.2</em> (superoxide dismutase) and <em>Solyc07g065840.2.1</em> (heat shock protein 90) response to ToLCBaV infection were analysed at different time intervals. A significantly positive correlation was observed for the expression profiles of all three circRNAs and their parent genes. Furthermore, the differential expression across samples as well as time interval indicates that CircRNA mediated gene expression is involved in viral resistance. The results of the expression assays of both superoxide dismutase and peroxidase were consistent with enzyme analysis. Overall findings demonstrated the importance of CircRNAs in ToLCBaVD resistance and suggested that CircRNAs could be key regulators of gene expression during disease resistance in tomato.</p> 2022-12-22T00:00:00+0530 Copyright (c) 2022 Bhavya Chidambara, Dayanandhi Elangovan, Sadashiva Avverahally , Krishna Reddy, Ravishankar Kundapura https://jhs.iihr.res.in/index.php/jhs/article/view/1352 The Morphological and molecular diversity of Ganoderma spp. causal agent of basal stem rot of coconut in Southern dry tracts of Karnataka 2023-01-03T15:23:05+0530 Palanna KB kbpalanna@gmail.com Koti P S kbpalanna@gmail.com Basavaraj S kbpalanna@gmail.com Boraiah B kbpalanna@gmail.com Narendrappa T kbpalanna@gmail.com <p>Morphological and molecular diversity of <em>Ganoderma</em> species causing basal stem rot of coconut in Southern dry tracts of Karnataka, India was carried out during 2016-17. A total of 20 isolates were isolated from Chitradurga, Chikamagalore, Hassan and Tumkur districts of Karnataka and were identified based on morphological and molecular characteristics. Sporocarps and diseased root bits were found as good source for isolation of <em>Ganoderma</em>. In all the isolates there were high variability in cultural, morphological and molecular characteristics. The dendrogram generated from the cultural and morphological characteristics showed clear variations among <em>Ganoderma</em> isolates and formed two main clusters, one cluster consisted of 13 isolates and another cluster consisted of 7 isolates. Several isolates showed 100 per cent similarity in the morphological characters regardless of their geographical origin. All the <em>Ganoderma</em> isolates amplified a fragment of 650 bp with fungal universal primers (ITS1 and ITS4). The ITS gene sequences of five isolates <em>viz</em>., CG1 (MK 681870), CG7 (MK681871), CG11 (MK681872), CG14 (MK681873) and CG20 (MK681874) were deposited in NCBI gene bank. Taxonomic comparison of the isolates with NCBI database proved that the isolates were genetically related to <em>Ganoderma</em> spp. with 80-100 per cent identity. However, all the tested isolates could not amplify <em>G. lucidum</em> species specific markers which indicate its absence in the region. The phylogenetic analysis of the Ganoderma isolates (ITS1 and ITS4) of coconut with other known species of <em>Ganoderma</em> from GenBank emphasized the close relationship with India, China and Sri Lanka isolates. The isolate CG1 grouped with <em>Ganoderma carnosum</em> (KR 733545.1) with 98.97 per cent identity which is isolated from Sri Lanka and CG14 and CG20 grouped with <em>G. applanatum</em> (MF 072395.1) and <em>G. gibbosum</em> (OM 350473.1) with 98 to 99 per cent identity and CG7 and CG11 isolates of coconut grouped into distinct sub cluster and clearly indicated the species diversity in <em>Ganoderma</em> infecting coconut in Southern Karnataka.</p> 2022-12-22T00:00:00+0530 Copyright (c) 2022 Palanna KB, Koti P S, Basavaraj S, Boraiah B, Narendrappa T https://jhs.iihr.res.in/index.php/jhs/article/view/1425 Ex-Situ Conservation of An Endangered Medicinal Plant Andrographis Paniculata By Plant Tissue Culture 2023-01-03T15:22:43+0530 Marjia Akhter Monika marjiamonika@gmail.com Mohammed Shafi Ullah Bhuiyan msubhuiyan@gmail.com Kishore Kumar Sarker kishoresarker@gmail.com Mst Maiful Akter Dina dina.sau.ag@gmail.com Sayeda Sultana lopacnu@yahoo.com <p>An effective and rapid <em>in vitro</em> regeneration protocol of Kalmegh (<em>Andrographis paniculata</em>) was established by investigating the factors like combinations of plant growth regulators and explant types (stem, leaf and midrib). To find out the effective medium for callus induction and shoot regeneration, different explants of <em>A. paniculata</em> were cultured on MS media enriched with several concentrations of 6-benzylaminopurine (BA), α-naphthalene acetic acid (NAA) and 2, 4-dichlorophenoxy acetic acid (2,4-D). Stem explant was noticed more responsive than leaf and midrib explant both in callus initiation and shoot regeneration. The ranges of callus initiation from stem, leaf and midrib explants were 26.67 - 100%, 20 - 93.33% and 13.33 - 73.33%, respectively. The calli obtained from midrib explants were not used in shoot initiation because of its poor size. The stem explant exhibited the maximum 73.33% shoot regeneration frequency in a comparison with leaf explants (60%). The maximum callus induction (100%) and shoot regeneration (73.33%) from stem explants were noticed in MS medium strengthened with 0.5 mg/L NAA and 2.0 mg/L BA and half strength MS media complemented with 0.1 mg/L NAA and 3.0 mg/L BA respectively. The highest shoot regeneration from the stem explant may be due to presence of more active parenchymatous cells than that of leaf explant. Half MS medium fortified with 2.0 mg/L IBA considered as best root initiation medium as it resulted in maximum rooting (93.33%). After acclimatization, the plants were transferred to field and found identical to the mother plant.</p> 2022-12-31T00:00:00+0530 Copyright (c) 2022 Sayeda Sultana, Marjia Akhter Monika, Kishore Kumar Sarker, Mst Maiful Akter Dina, Mohammed Shafi Ullah Bhuiyan https://jhs.iihr.res.in/index.php/jhs/article/view/1232 Phenotypic trait association studies in brinjal upon drought stress 2023-01-03T15:29:35+0530 Mahammed Faizan faizanscf@gmail.com Harish Babu BN harishgpb@gmail.com Lakshmana D lakshmanad@rediffmail.com Ganapthi M gana.cph@gmail.com Rakshith M mrakshith94@gmail.com <p>Eggplant is popularly known as poor man’s vegetable.
