Abstract
In a 10x 10 half dialled:1 eros.'; of cowpeu cultivars ,,"ulysed to obtuin husic information on the genet 13 control;, 1~ ~h ~ expression of somt' •. _It lype var~a~les, bi-directional domnanc? wa!' observed for uniformity of poc: l)ening (UPR). For duration of rerroduction period (ORP) and branch fruiting pote1',!;a! (BFP), dominance was towards a decreasl: in their values, whereas for nodes/main stem :'·"MS). pods/main stem (PMS) average inter'1od.~ length (AIL), and efficiency in pod fill (EPF), the direction of dominance was towards an increase in their values. The inheritance of all the characters involve both additive and nonadditive gene effects, with additive gene effects predominating for average internode length ~ArL). A measure of the degree of dominance indicated partial to complete dominance for the characters. Regression coefficients of Wr on Vr indicated the absence of non-allelic interactions to the genetics of all the characters.
