Open full text 6 citations

Abstract

In crop improvement, a wild species is valued if it possesses traits of agronomic importance and can \nbe hybridized easily with cultivated species. The genus Cajanus has 32 species, of which only \npigeonpea, [Cajanus cajan (L.) Millsp.] is cultivated. Cajanus scarabaeoides, one of the closely \nrelated wild species of pigeonpea, has high level of tolerance to drought and resistance to insectpests.
