Abstract
Regression coefficient ‘b1’ deviated from unity for length of main raceme, Number of secondary branches per plant, test weight, oil content, Number of siliquae per plant, seed yield per plant. The estimates of additive components ( Dˆ ), dominance components ( 1 Hˆ and 2Hˆ ) were highly significant for days to flowering, days to maturity, plant height, length of main raceme, number of siliquae per plant, number of secondary branches per plant, oil content, test weight and seed yield per plant .All the estimates of Fˆ (mean of Fr value, where Fr is the proportion of negatives effects of Genes in rth parents) was positive and significant number of siliquae per plant, days to flowering, days to maturity, plant height and except for which is highly significant whereas days to maturity was negative and significant. The estimates of 2 hˆ were positive and highly significant for days to flowering, days to maturity, plant height, length of main raceme, oil content, test weight and seed yield per plant. The estimates of mean degree of dominance ( 1Hˆ / Dˆ ) 0.5 were more than unity for length of main raceme, number of secondary branches per plant, oil content, test weight and seed yield per plant.
