Inheritance of epicotyl colour in pigeonpea [Cajanus cajan (L.) Milisp.]

Abstract

Majority of the pigeonpea [Cajanus cajan (L.) Millsp.] accessions in the germplasm are having purple epicotyl colour which is later converted into green or brown stem. The inheritance pattern has been studied by previous workers for green and purple stem pigmentation [1]. However, the report on inheritance of epic,otyl colour is lacking. Patil et al. [2] isolated such seedling markers for use in hybrid pigeonpea breeding. The present study was undertaken to investigate the inheritance pattern of green epicotyl colour and its linkage relationship with genetic male sterile being used for hybrid pigeonpea seed improvement.
