Twenty cultivars of onion were studied for storage life under ambient conditions for four months. The minimum per cent of sprouting was observed in Arka Bindu (0.61 % and 2.06 %), whereas, the Agrifound dark red recorded the maximum per cent of sprouting (6.23 % and 17.28 %) after three and four months of storage, respectively. The minimum per cent of rotten bulbs was observed in Arka Bindu (1.84 % and 3.28 %), whereas, the agrifound dark red recorded the maximum rotten bulbs (3.78 % and 17.28 %) after three and four months of storage, respectively. After one month of storage the minimum storage loss in weight observed in Arka Bindu (1.60 %), whereas, maximum recorded in Agrifound dark red (6.03 %). While, after two months of storage the minimum storage loss in weight was observed in Bhima Kiran and Bhima red (5.50 % each), whereas, the maximum was recorded in Arka Kalyan (6.03 %). After three months of storage the minimum total loss in weight was observed in Bhima Kiran (7.73 %), whereas, maximum was recorded in Agrifound dark red (28.50 %).While, during four months of storage the minimum total loss in weight was observed in cultivar Arka Bindu (12.80 %).
Germplasm (44) from 6 wild Abelmoschus species and 4 cultivars from cultivated species [Abelmoschus esculentus (L.) Moench] were evaluated during kharif 2015 and 2016 to assess the genetic variability and character association in yield attributes and YVMV disease. Significant differences among accessions for mean performance with respect to 13 quantitative traits revealed presence of sufficient variation in the experimental material used. Mean Percent Disease Incidence (PDI) YVMV, revealed lowest PDI in A. moschatus (IC-141055) (7.73%) followed by IC90476- 1(8.61%) and IC47092 (11.0%). These wild accessions indicated their scope in future breeding programs for resistance to BYVMV. Estimates of genotypic coefficients of variability (GCV) and phenotypic coefficients of variability (PCV) ranged from 6.15-59.14 and 13.98- 62.13 respectively. Heritability in broad sense (h2), genetic advance (GA) and genetic advance as percentage of mean (GAM) ranged from 19-98%, 0.40-84.20, 5.58- 98% respectively. Further classification revealed high GCV (>20.00%), high heritability (>60.00%) and high GAM (>20.00%) for most of the yield components and PDI of BYVMV, except for first flowering node and stem diameter. Character association study publicized significant positive association and high positive direct effect of fruit weight (0.85), number of fruits per plant (0.532), stem diameter (0.088), plant height (0.069) and fruit diameter (0.046) on fruit yield per plant. Therefore, direct selection based on these combinations of traits help in harnessing their positive direct effects on yield per plant in okra improvement programmes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
