Genetical studies inCajanus cajan (L.) Millsp. : I. Genetics of pod colour.
From three sets of crosses involving the phenotypes chocolate, red oxide, green with chocolate streaks and green with red oxide streaks, the action of the genes governing the phenotypes of the pods ofCajanus cajan (L.) Millsp. has been proposed. GeneL controls production of chocolate colour,L (r) an allelomorph ofL hitherto unreported, controls production of red oxide colour and geneD controls distribution of this colour. As regards inheritance of these two genes, the relationships betweenL andL (r) isL>L (r) andD is incompletely dominant overd. The genotypes of the different phenotypes have been presented.
