Abstract:
The mean performance of the genotypes revealed a wide range of variability for all the traits. The variation was highest for plant height at 60 DAS (26.3-72.75cm) followed by plant height at 90 DAS (82.99-162.75cm), seed yield per hectare (3.61-22.49q), number of leaves per plant at 90 DAS (22.2-53.07), days to first flowering (45.67-67.00), days to 50% flowering (57.00-76.00), number of umbel per plant (17.2-37.00), number of primary branches per plant (4.8-10.40), plant height at 30 DAS (4.49-11.27cm), number of leaves per plant at 30 DAS (5.33-13.27), number of seeds per umbel (17.6-32.6), number of secondary branches per plant (8.13-15.47), number of leaves per plant at 60 DAS (10.07-19.33), days to germination (11.33-19.33), test weight (10.23-17.13g), number of umbellets per umbel (5.00-8.73) and days to maturity (103-118). While it was low for while number of seeds per plot (0.21-1.35kg) and seed yield per plant (5.13-9.53g) was found to be lowest. The values of heritability in broad sense was found to be estimates were observed very high for Plant height (cm) at 90DAS, followed by Plant height (cm) at 60DAS, Plant height (cm) at 30DAS. Genetic advance as percentage of mean ranged between 5.84% for Days to maturity to 58.38% for Seed yield/ ha (q). The highest estimate of genetic advance as percentage of mean was recorded for Seed yield/ ha (q), Seed yield/ plot (kg), No. of leaves / plant at 30DAS, No. of leaves / plant at 90DAS, plant height at 60DAS and plant height at 90DAS. In the present findings phenotypic coefficient of variations were observed to be higher than the corresponding genotypic coefficient of variation for all the characters studied, however, the differences were narrow which implied their relative resistance to environmental variation.
