Abstract:
The present investigation was conducted to estimate the extent of genetic variability, heritability and genetic advance. The experimental material comprising of 31 genotypes were evaluated at Experimental farm Department of Agril. Botany, College of Agriculture, Latur during Rabi- 2021- 2022. The material was sown in randomized block design with two replications, on 29th of October, 2021 with the spacing of 30 cm x 5 cm. Observations were recorded for ten characters viz., days to 50% flowering, days to maturity, plant height (cm), number of primary branches, number of secondary branches, number of capsule per plant, number of seed per capsule, 1000-seed weight, oil content (%) and seed yield per plant. Substantial amount of genetic variability had been found for all the characters, which was indicated by significant difference among and between treatments. The mean performance of the genotypes confirmed higher seed yield per plant for EC- 41741, JLS- 395, ES- 1445, EI-5511 and FR- 111. The genotype EC- 41741 recorded best mean values in desirable direction for seed yield per plant, 1000 seed weight, number of primary branches per plant and number of capsule per plant. Genotypes like JLS- 395 and ES- 1445 were also seen promising for the characters like days to 50% flowering, days to maturity, plant height, number of primary branches per plant, capsule per plant, 1000 seed weight and oil content in the desired direction. The estimates of GCV and PCV were recorded high for seed yield per plant, number of primary branches, number of capsule per plant, number of secondary branches and 1000 seed weight. Higher heritability estimates were observed for all the traits under the study. However, high genetic advance as percent of mean was noted for number of capsule per plant, plant height (cm), days to maturity, and number of secondary branches. Whereas moderate for days to 50% flowering, oil content, seed yield per plant and number of primary branches, were the characters number of seed per capsule, and 1000- seed weight is low.
