Trees grown under HDP have lower TCSA in comparison to normal density. Primary and secondary branch girth were maximum in ‘Bigarreau Napoleon’ whereas, annual extension growth and shoot thickness were high in ‘Steela’. Yield, yield efficiency and cumulative yield efficiency were registered maximum in ‘Bigarreau Napoleon’ and ‘Bigarreau Noir Grossa’ cultivars. Largest fruit weight, fruit length and fruit diameter were found maximum (10.16 g/fruit), (25.51 mm) (25.20 mm) respectively in ‘Bigarreau Napoleon’. Total soluble solids were found maximum in ‘Bigarreau Noir Grossa’ (17.30 0Brix) among the studied cultivars. Correlation matrix showed that TCSA had positive correlation with canopy volume, primary branch girth and secondary branch girth and fruit weight showed positive correlation with fruit length and fruit diameter.</p> K K Srivastava, Dinesh Kumar, P Barman ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jhs.iihr.res.in/index.php/jhs/article/view/694 Thu, 20 Jun 2019 00:00:00 +0530 Effect of cultivars on tree growth, yield and quality attributes of apple on espalier architecture under high density planting system https://jhs.iihr.res.in/index.php/jhs/article/view/693 <p>Annual extension growth (AEG), an indicator of tree vigor, was recorded maximum (145.63 cm) in Granny Smith and minimum (111.04cm) in Spartan, where as correlation matrix showed negative relation between trunk cross sectional area (TCSA) and AEG. Granny Smith exhibited maximum (184.09 g) fruit weight and it was minimum (128.68 g) in Spartan, the correlation matrix between fruit weight and yield efficiency exhibited significant positive correlation over the years. Yield tree-1 was maximum (29.45 kg tree-1) in Coe red Fuji and minimum (16.04 kg/tree) in Spartan. Significant and positive correlation coefficient (0.870) observed between yield and TCSA. TCSA has positive correlation with fruit weight and yield efficiency, maximum mean yield efficiency (1.11 kg/cm2) was recorded in Granny Smith. All the cultivars trained on this architecture had high chroma values (color intensity).</p> K K Srivastava, Dinesh Kumar, S R Singh, O C Sharma ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jhs.iihr.res.in/index.php/jhs/article/view/693 Fri, 21 Jun 2019 00:00:00 +0530 Heterosis and combining ability for yield and its related traits in ridge gourd [Luffa acutangula (L.)Roxb.] https://jhs.iihr.res.in/index.php/jhs/article/view/695 <p>Line × Tester analysis involving three lines and four testers was carried out in ridge gourd [Luffa acutangula (Roxb.) L.]. Significant variation was noticed in the mean performance of the parents and hybrids for all the characters studied except for vine length and fruit girth. The results from GCA and SCA variance indicated the predominance of non-additive gene action for all the traits except fruit girth. Significant heterosis of 177.78% over standard check, Arka Sumeet for fruit weight per plant was expressed by the cross GARG-1 × CO-1. The best general combiners were GARG-1 and Pusa Nutan among the lines, and Jaipur long and CO-1 among testers. Best specific combining ability effects for fruit length and yield (t/ ha) were recorded by the crosses Pusa Nasdar × Arka Sumeet and GARG-1 × CO-1.</p> Varalakshmi B, Pitchaimuthu M, Sreenivasa Rao E ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jhs.iihr.res.in/index.php/jhs/article/view/695 Tue, 01 Jan 2019 00:00:00 +0530
