Mushrooms have been variously used in different cultures from being priced as “Food of Gods” in the Roman culture to tools of psychological sedation for the Mexican warriors. Most of the edible mushrooms are saprophytic growing on decomposed organic plant matter. Mushrooms play varied and important roles in human nutrition and health. They are unique nutrition dense vegetables with quality high protein, very low fat, zero cholesterol, low carbohydrates, low glycemic index, high fiber, good cardiac friendly sodium to potassium ratio and some unique bioactive compounds like ergothioneine and polysaccharides. These unique nutritive properties of mushrooms make them a recommended food for diabetics, body weight management, hypertension and cardiac well-being. The concept of selenium rich mushrooms for slowing down the progress of AIDS has been gaining importance in the recent years. Apart <br>from being a healthy vegetable, the unique lignocellulosic waste-based production system of mushrooms makes them the most ecofriendly zero waste green technology with immense environmental benefits (Gupta et al., 2004, Jain et al., 2014 and &amp; Pandey et al., 2014). Despite many environmental and nutritional benefits; mushrooms yet have not become a part of daily nutrition in the Indian diet and the per capita consumption still remains very low at 70 grams per annum. There is a need to educate and enhance the awareness among the people about the nutritional and health potential of mushrooms. There is also the need to draw the attention towards integrating mushroom technology in successful agro-residue management programs, livelihood programs, national nutrition programs and women empowerment and rural development schemes which ultimately culminate in providing better daily nutrition.</p> 2022-09-23T15:28:26+0530 Copyright (c) 2022 Meera Pandey, G.C.

In this study, 80 accessions were evaluated for 16 yield and yield attributing traits. The Mahalanobis’ D2 analysis grouped these accessions into seven clusters. Cluster I was the largest with 69 genotypes followed by cluster III comprising six genotypes while, the clusters II, IV, V, VI and VII contained one genotype each. Among the traits studied, yield contributed maximum (38.04 %) towards diversity, followed by root weight (26.58%), root color (9.18%) and plant height (6.7%). As far as root weight (g) [d1], leaf weight (g), root weight (g), number of leaves, TSS(°Brix), leaf weight (g), root diameter (mm), core diameter (mm), and root cracking are concerned, they contributed 3.45, 2.09, 1.77, 1.71, 1.55, 1.52, 1.46, 1.33, 1.01 and 0.82 percent respectively. Diversity analysis has given an indication about the genetic variation among the carrot accessions which will prove useful in selection of diverse parents in crop improvement programme.</p> 2022-06-30T00:00:00+0530 Copyright (c) 2022 Manisha, Padmini K, Veere Gowda R, Dhananjaya M V https://jhs.iihr.res.in/index.php/jhs/article/view/1007 Characterization, inheritance of male sterility and development of male sterile and maintainer lines in ridge gourd (Luffa acutangula (Roxb.)

Rajasekharan.PE@icar.gov.in <p>Two male sterile mutants IIHRRG-12MS (long fruited) and IIHRRG-28MS (medium long fruited) were identified from the ridge gourd germplasm IIHR-12 and IIHR-28 respectively at ICAR-IIHR, Bengaluru. These two male-sterile (ms) sources were characterized by the production of rudimentary male flowers in the racemes in contrast to the bright yellow flowers with fertile pollen and healthy anthers in male fertile, monoecious plants. Using these ms lines the inheritance of male sterility was worked out, which is cytoplasmic genic male sterility (CGMS) type, with single dominant gene either in homozygous or heterozygous condition restoring male fertility in the presence of sterile cytoplasm. In order to develop F1 hybrids using male sterility, several male sterile and maintainer lines were developed in different genetic back grounds such as green/dark green fruit colour and short/medium long/long fruit length.</p> 2022-09-24T13:48:13+0530 Copyright (c) 2022 Varalakshmi B, Rajasekharan P.E. https://jhs.iihr.res.in/index.php/jhs/article/view/1186 Ploidy analysis among Citrus mutants using leaf meristematic tissue 2022-09-28T14:00:51+0530 Vijayakumari Narukulla narukullav@gmail.com Yogesh Lahane yogeshlahane@gmail.com Rekha A arekha2001@yahoo.com <p>A promising method for preparing metaphase spread for counting the number of chromosomes from the emerging shoot tissue is described in this report. In the present study, we adopted enzymatic digestion of shoot tips to analyse the chromosome number. The chromosomes in metaphase stage of cell division are highly condensed and easy to count in routine cytological technique. Even the morphological features like position of centromere can be seen in metaphase. In prophase it may not be clear as the chromosomes are getting ready for cell division. In enzymatic digestion even the prophase chromosomes are visible, which can be counted. Hence enzymatic digestion technique is more efficient in citrus as compared to acid digestion method as the citrus crop is a perennial crop with small-sized chromosomes. Furthermore, the sample collection in the field was easy and actively growing vegetative flush was available throughout the year. This technique was attempted in the tissue culture lab of ICAR- CCRI in various in vito and in vivo ploidy induction experiments in Citrus sinensis Osbeck (Sweet orange cv. mosambi), C. reticulata Blanco (Nagpur mandarin) and C. jambhiri Lush (Rough lemon), for confirmation of diploidy (2n=2x=18), triploidy (2n=3x=27), tetraploid (2n=4x=36), hexaploid (2n=6x=54).</p> 2022-09-24T13:58:27+0530 Copyright (c) 2022 Vijayakumari Narukulla; Yogesh Lahane, Rekha A https://jhs.iihr.res.in/index.php/jhs/article/view/1226 Genetics of growth and yield attributing traits of brinjal (Solanum melongena L.) through six generation mean analysis 2022-09-28T14:00:20+0530 Satyaprakash Barik satyabarik001@gmail.com Naresh Ponnam nashhorti@gmail.com Gobinda Acharya Gobinda.Acharya@icar.gov.in TH Singh singh.ht@icar.gov.in Meenu Kumari meenu10iari@gmail.com manasi dash manasi_dash@yahoo.com <p>Understanding gene action of different traits is of utmost importance for formulating successful breeding programs. The population was developed involving Arka Neelachal Shyama and CARI-1 to inquire the gene actions controlling the inheritance of several growth as well as yield attributingparameters through six-generation mean analysis. Three parameter model revealed the insufficiency of the simpler additive dominance model for the evaluated traits, referring to the existence of inter-allelic interactions. Six parameter model was implemented to better understand gene actions. Most of the yield and attributing traits under study except number of branches showed a high estimate of dominance as well as environmental variance, disclosing a lower extent of heritability. The number of branches was observed to be controlled by duplicate epistasis. Hence, for the fixation of this trait, the best strategy is to exercise minimal selection during advance generations, followed by intense selection during later generations (F<sub>4-</sub> population onwards). The preponderance of the narrow sense type of heritability revealed that dominant effects were predominantly accountable for the existing genetic variation. Hence, recurrent selection followed by bi-parental mating and selection during the later stage of generations is advised to increase the occurrence of favorable alleles and accumulation of desirable genes.</p> 2022-09-24T14:09:47+0530 Copyright (c) 2022 Satyaprakash Barik, Naresh Ponnam, Gobinda Acharya, TH Singh, Meenu Kumari, manasi dash https://jhs.iihr.res.in/index.php/jhs/article/view/1245 Assessing the genetic diversity of squash (Cucurbita pepo L.) genotypes based on agro-morphological traits and genetic analysis 2022-09-28T13:59:37+0530 Muhtasim Billah Sajid muhtasimbillahsajid@gmail.com Kishore Kumar Sarker sarkerkishore@gmail.com Fakhrul Islam Monshi monshifi.gpb@sau.ac.bd Sayeda Sultana sultana.gpb@sau.ac.bd Marjia Akhter Monika monika.gpb@sau.ac.bd Mohammed Shafi Ullah Bhuiyan bhuiyanmsu.gpb@sau.ac.bd <p>An experiment was conducted to estimate the genetic variability of 15 indigenous and exotic squash genotypes assessing 18 quantitative and 8 qualitative traits. Results showed that the accessions have high variability in qualitative traits like fruit size, fruit shape, fruit skin colour,lustre and fruit productivity, which allowed selection for considerable gains in these characteristics. The quantitative traits such as fruits yield per plant, fruit weight, length, diameter and total yield per hectare showed the greater phenotypic coefficient of variation (PCV) along with higher heritability which can helps to identify desirable genotypes. The obtained significant and positive correlation between fruit yield with number of leaves, nodes, fruit length, weight and number could assist in selection to improve this crop. Cluster analysis resulted in the formation of 4 groups, confirming the genetic variability among the studied genotypes. Eventually, the attained PCA analysis result revealed that the number of fruits per plant, fruit yield per plant, fruit length and days to first female flowering are the most discriminating traits which are accelerating the variability in squash genotypes. On the basis of the yield and its attributing traits, First Runner is the best genotype suited in this environment.</p> 2022-09-24T14:22:55+0530 Copyright (c) 2022 Muhtasim Billah Sajid, Kishore Kumar Sarker , Fakhrul Islam Monshi, Sayeda Sultana, Marjia Akhter Monika, Mohammed Shafi Ullah Bhuiyan https://jhs.iihr.res.in/index.php/jhs/article/view/1214 Diversity analysis of phenotypic traits in okra (Abelmoschus esculentus L. Moench) 2022-09-28T13:59:16+0530 Aman Deep Ranga aman_ranga94@yahoo.com Ankush Chaudhary ankushjaat199@gmail.com Mayur S. Darvhankar mayur.21878@lpu.co.in <p>It is necessary to obtain cultivars which provide high yield by exploiting desirable traits from wild genotypes of okra (Abelmoschus esculentus L. Moench). Okra genotypes were evaluated for phenotypic traits during 2018. High genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) occurred for nine traits and narrow differences between GCV and PCV indicated the influence of environment was negligible. High estimates of heritability, coupled with moderate to high genetic advance as a percent over mean, were recorded for nine traits. Thousand seed weight had a positive, significant, correlation with yield per hectare. Plant height and number of fruits per plant had direct and positive effects towards the yield per hectare The principal component analysis indicated the first 3 principal components contributed 80.517% of total variation among traits describing genotypes. Cluster analysis indicated hybridization of genotypes among inter-cluster I and II could be used to develop stable, uniform varieties in diverse climatic conditions. EC359637 and IARI Selection 2 are distantly placed and can be used for overall improvement in further crop breeding.</p> 2022-09-24T14:51:12+0530 Copyright (c) 2022 Aman Deep Ranga, Mayur S.

The demand for jasmine flowers is growing day by day owing to its wide range of uses and there is a pressing need for improving the crop by exploring strategies to evolve diverse genotypes. The present study focuses on the hybridization of Jasminum spp with the objective of introgression of desirable traits that would aid in creation of wider genetic variability. Pollination is the basis in any hybridization programme. The main aim of this research study was to determine the suitable pollination methods among self, open and cross pollination and to assess the effect of the pollination methods on the fruit set and fruit characteristics. The results of the study revealed that the overall response of J. auriculatum was found effective with maximum fruit set percentage. J. auriculatum cv Parimullai yielded the highest fruit set of 76.43% under open pollination and the least fruit set rate of 2.14% under self-pollination. Among the possible cross combination involving J. auriculatum and J. grandiflorum cultivars as seed parents with various pollen parents, J. flexile showed considerable results. Cross combination of J. auriculatum x J. flexile recorded maximum fruit set revealing best cross compatibility while crosses involving J. sambac resulted in no fruit set indicating the prevalence of fertilization barriers that hinder hybridization.</p> 2022-09-24T15:12:03+0530 Copyright (c) 2022 Usha, Ganga M, Rajamani K, Manonmani S, Gnanam R https://jhs.iihr.res.in/index.php/jhs/article/view/846 Studies on genetic variability and relationship of bael (Aegle marmelos (L) Correa) using morphological and molecular markers 2022-09-28T13:58:34+0530 Amulya R N amulyahiriyur@gmail.com Nagarajappa Adivappar amulyahiriyur@gmail.com Shivakumar B S amulyahiriyur@gmail.com Satish K M amulyahiriyur@gmail.com <p>Bael (Aegle marmelos (L) Correa) is an important underutilized fruit crop of India. A total of 25 bael trees were selected from 356 bael trees of Sakharayapattana in Chikkamagalur district, Karnataka, India based on the fruit morphological traits (fruit weight, pulp weight, skull thickness, seed weight per fruit, No. of seeds per fruit, No. of locules per fruit, No. of seeds per locule, pulp wt. : seed wt.). These 25 trees were evaluated for phenotypic and genotypic variations using random amplified polymorphic DNA (RAPD) and inter-simple sequence repeats (ISSR) markers. RAPD and ISSR markers showed significant polymorphism among the trees. Jaccard’s genetic similarity value of RAPD and ISSR was found in the range of 0.00–0.95 and 0.06–0.56, respectively suggesting a moderate level of genetic diversity. The present study revealed that molecular markers can be successfully utilized for determining genetic diversity and relationship of bael trees for further varietal improvement.</p> 2022-09-27T14:40:08+0530 Copyright (c) 2022 Amulya R N, Nagarajappa Adivappar, Shivakumar B S, Satish K M https://jhs.iihr.res.in/index.php/jhs/article/view/1052 Molecular characterization of ginger genotypes using RAPD and SSR markers 2022-09-28T13:58:13+0530 Akshitha HJ akshi.hosahalli10@gmail.com Prasath D dprasath@gmail.com Umesha K umesha_k@yahoo.co.in Mohammed Faisal P faisal.tnau@gmail.com Venkataravanappa V venkatrajani@gmail.com <p>Genetic diversity among ginger genotypes collected from different parts of the country was studied using molecular markers (30 RAPD and 55 SSR). Compared to RAPD primers SSR primers were efficient in distinguishing the genotypes. A total of 86 and 23 polymorphic bands were observed with RAPD and SSR primers, respectively. Percentage polymorphism observed between RAPD and SSR primers was 97.40 % and 56.54 %. Grouping of genotypes by using combined data of RAPD and SSR primers indicated that irrespective of their place of collection or geographical origin, 30 genotypes were clustered into different groups which showed that, each individual genotype is having wider variability or it might be due to the genetic similarity existing among them.</p> 2022-09-27T14:46:06+0530 Copyright (c) 2022 Akshitha HJ, Prasath D, Umesha K, Mohammed Faisal P, Venkataravanappa V
