Abstract:

Although Rapeseed is the most important and most widely cultivated oilseed crop in Assam, its yield is much below the national average. The present investigation was conducted to evaluate genetic variation and performance for yield traits in 14 segregating breeding populations and 4 parent rapeseed varieties (Jeuti, TS 38, YSH 401 and NRCYS 05-03) using randomized block design (RBD) with three replications. Significant differences were observed for all the 13 characters from the pooled analysis of variance. High genotypic and phenotypic variation and high heritability coupled with high genetic advance were observed for number of secondary branches per plant, harvest index, seed yield per plant and biological yield per plant. JT 15-10-1, JT 15-9 and JT 15-1 were the three best populations having high seed yield per plant and high mean performance for various yield attributing and developmental characters.
