Summary Seedcoat colour in greengram (Vigna radiata (L.) Wilczek.) is a useful marker for genetic studies and varietal identification. Its mode of inheritance was examined in five crosses among nine parents which differed for seedcoat colour. Four of the parents had sap green seedcoat colour while the others had ‘raw sienna’, ‘brownish green’, ‘densely black spotted’, ‘black’ and ‘greenish yellow’ seedcoat colour, respectively. At the F2 generation, no more than 20 different colour classes were observed. The segregation in F3 and backcross generations indicated that at least five major genes were involved in seedcoat colour inheritance. Sap green seemed to be dominant over raw sienna. The segregation ratios further indicated the role of non-allelic gene interactions (epistasis) in inheritance of seedcoat colour. Gene symbols were assigned to each colour and genotypes to each parent.
