Characters Association of Some Quantitative Traits with Grain Yield in Indian Mustard [Brassica juncea (L.) Czern and Coss.]

The experimental materials comprised of 79 treatments (15 lines, 4 testers, 60 F1) of Indian mustard. Were grown at Genetics and Plant Breeding research form, Narendra Deva University of Agriculture and Technology, Narendra Nagar, Faizabad (U.P.) under timely shown during rabi 2012–13 to study genetic variability of yield and its component traits. Seed yield per plant had significant and positive association with biological yield per plant (0.880) followed by plant height (0.548), harvest index (0.466), number of siliquae on main raceme (0.274) and length of main raceme (0.202) but it had significant negative association with 1000-seed weight (−0.190). The estimates of genotypic correlation coefficient were generally, similar in sigh or nature but higher in magnitude than the corresponding phenotypic correlation coefficient. Grain yield per plant had strong and positive association with biological yield per plant, plant height, harvest index, number of siliquae on main raceme and length of main raceme at phenotypic and genotypic level. Thus biological yield per plant followed by plant height, harvest index, number of siliquae on main raceme and length of main raceme emerged as most important and strongest associate of grain yield across diverse environment. The study revealed that greater emphasis should be given to these characters for yield improvement.
