摘要

Pigeonpea is a partially cross-pollinated crop. The out-crossing nature of pigeonpea is being exploited for hybrid breeding using stable genetic male sterility discovered by Reddy et al. (1978). Commercial production of pigeonpea hybrid using geneticmale-sterile lines poses problems of seed purity as fertile plants from the plots must be rouged out. The alternative has been to look for cytoplasmic-genic male-sterile lines, which has been successfully exploited in several crops and has overcome manyof the disadvantages associated with the genetic male-sterile systems. Attempts to obtain cytoplas-mic male sterility in spontaneous mutants in the world pigeonpea collection have been unsuccessful (Reddy et al. 1978), Wide hybridization involving conventional backcrossing of Cajanus sericeus and C. cajan with multiple genome transfer led to the development of cy-toplasmic-genic male sterility in pigeonpea (Ariya-nayagam et al. 1995).
