Abstract:
The experiment was conducted at Research Farm of Department of Genetics & Plant Breeding, ANDUAT, Narendra Nagar, Ayodhya (U.P.) during rabi, 2018 with 28 yellow mustard genotypes for assessment of genetic variability. The analysis of variance (ANOVA) was found significant for all the characters under study. The genotype NDYS-2 followed by YSCN16-3, NDYS16-6, YSCN-2 and YSCN16-5 producing higher seed yield per plant. The highest estimates of PCV and GCV was observed in case of seed yield per plant (g) (PCV 29.193%, GCV = 25.546%) followed by primary branches per plant (PCV = 25.407%, GCV = 21.573%), and number of seed per silique (PCV = 21.645%, GCV = 20.891%) recorded higher for GCV and PCV. The heritability in broad sense was recorded higher of character length of main raceme (94.00%) followed by number of seed per silique (93.10%), oil content (%) (90.10%), silique on main raceme (79.30%), and seed yield per plant (g) (76.60%). The genetic advance as per cent of mean recorded higher for number of seed per silique (41.53%), primary branches per plant (37.73%), silique on main raceme (30.97%), and length of main raceme (27.87%). The high estimate of heritability coupled with high genetic advance for seed yield per plant (g), number of seed per silique, silique on main raceme, and length of main raceme.
