Summary

Five types of localization of the seed coat colours black, chocolate and khaki in lablab are described-micropylar colour, caruncular patch, dorsal patch, marbled and eye patterns. These patterns are produced by the interaction of five factors, K, CP, Dp, M and Bf. The factor K alone causes micropylar colour, the factors K and Cp together produce the caruncular patch pattern and the dorsal patch pattern is formed when the three factors K, Cp and Dp are all present. The factor M produces the marbled pattern. The combined presence of K, Cp, Dp and M results in the eye pattern. The factor Bf for buff seed coat also converts any of the above patterns into whole colour. There is also another factor pair, Sp, sp, for even distribution of colour v speckling of the two colours black and chocolate. Speckling is not found in buff and khaki seeds.
