Abstract

Direct and reciprocal crosses were attempted between two contrasting pigeonpea varieties viz., Vamban-1 and Gulbarga-1. The study of parents, hybrids and F2 segregating population revealed that the characters such as duration, leaf colour, resistance to sterility mosaic disease and growth habit are monogenetically controlled and are inherited as a linkage block or single unit of recombination. The linkage block has been designated as EDgRDt and its allelic block as edgrdt.

Keywords: Pigeonpea, monogenic, linkage block.
