Abstract:
The experimental material comprising of 100 treatment viz., (10 parents + 45 F₁'s and 45 F₂'s) was evaluated in Randomized Block Design with three replications during Rabi 2020-2021, considerable variability for all 16 different characters under study. Number of secondary branches per plant, number of siliqua per plant, 1000-seed weight , harvest index and erucic acid showed moderate GCV and moderate PCV (10-20%) estimates in both generations. The estimates of heritability varied from 4.8% (number of seed per siliqua) to 31% (days to maturity) in F₁’s and 1.8% (oil content) to 41.0% (leaf area index) in F₂’s generation. The estimate of genetic advance over per cent of mean of the character ranges from 4.03% (days to 50% flowering) to 52.39% (total glucosinolate) and 3.65% (days to maturity) to 48.87% (total glucosinolate) in F₁ and F₂ generation respectively. Hence selection will be effective for this traits.
