Inheritance of Some Characteristics in Broad Bean (Vicia faba L)

Mohammed Y. Al-Fahady

Abstract


The importance of additive , dominance and epistasis effects on heading and maturity date, yield and its components traits was studied in two broad bean hybrids (FrenchXSyrian) and (Tewwtha X Babylon) by generation means analysis by developing six generations; viz, P1, P2, F1, F2, Bc1 and Bc2.The studied generations were significantly different at 1% level for all characters except for plant height and no. of seeds per pod in both crosses.Additive effects were significant for flowering and maturity date in both crosses while dominance effects were significant for seeds yield in (FrenchXSyrian) and no. of pods in (Tewwtha X Babylon) cross. AdditiveXadditive interactions were significant for plant height , no. of pods, 100 seed weight and seeds yield in (FrenchXSyrian) and for maturity date and no. of pods in (Tewwtha X Babylon) cross. AdditiveXdominance interactions were significant for flowering date in (FrenchXSyrian) cross while dominanceXdominance interactions were significant for flowering date in (FrenchXSyrian) and plant height , flowering date and seeds yield in (Tewwtha X Babylon)cross. Broad sense heritability (H2) estimates were moderate for plant height, flowering and maturity date and no. of pods in (FrenchXSyrian) and for plant height , no. of seeds per pod in (Tewwtha X Babylon) cross , while narrow sense heritability (h2) estimates were moderate for plant height, no. of pods and 100 seed weight in two crosses .
