Abstract:
Highly significant differences were recorded among the treatments for all the characters. Analysis of variance further indicated highly significant differences among the parents except biological yield, F1s indicated highly significant differences except no. of secondary branches per plant, no. of seeds per siliqua and biological yield per plant, parent vs F1s for all the characters. The estimates of all genetic components were found highly significant for Days to 50% flowering, Days to maturity, plant height, no. of primary branches per plant, number of secondary branches per plant, number of siliquae per plant, no. of seed per siliqua, 1000- seed weight, biological yield per plant, harvest index, oil content and seed yield per plant. The estimates of mean degree of dominance were more than unity for number of secondary branches per plant, no. of seeds per siliqua, 1000- seed weight, biological yield per plant, harvest index, oil content and seed yield per plant. The proportion of genes with positive and negative effects was near or equal to theoretical value for all characters except seed yield per plant.
