Studies in Dolichos lablab (Roxb.) and (L.) - the Indian field and garden bean. II

Abstract

There are four seed coat colours in Dolichos lablab, namely, Black, Chocolate, Khaki and Buff. Khaki is the basic colour for the other two colours Chocolate and Black. In Buff, the body of the seed coat is coloured Buff, but the micropylar zone remains white. In the first three colours, the colour may be either on the whole of the seed coat or confined to the micropylar and caruncular zone. A factor K has the effect of producing the Khaki colour and colouring the micropylar zone. A factor Bf has the effect of producing the Buff colour and colouring the whole of the seed coat except the micropylar zone. It is found that K bf and k Bf are absolutely linked.
