Abstract:
The present study was conducted on twenty one F₁ crosses of Toria, developed by crossing 10 parents (7 lines and 3 testers) in line x tester fashion in completely randomized design with three replications at Himgiri Zee University, Dehradun under normal sown condition during Rabi 2020-21. The observations were recorded for 14 yield contributing traits. The statistical analysis for genetic variability was done using Windostat 9.2. The analysis of variance revealed significant difference among the crosses for different traits. The results indicated that high heritability values were observed for days to 50% flowering, number of primary branches per plant, number of secondary branches per plant, length of main shoot, siliqua on main shoot, siliqua length, plant height, number of siliqua per plant, number of seeds per siliqua, seed yield per plant, days to maturity and harvest index. High GCV and PCV values were observed for important yield contributing traits like number of primary branches, number of secondary branches, length of main shoot, siliqua on main shoot, number of siliqua per plant, seed yield per plant and harvest index. The results indicated that experimental material taken into consideration had sufficient amount of genetic variability which can be utilized further in crop improvement programme.
