Diversifying cytoplasmic sources in rice

M. Rangaswamy | P. Jayamani

Discipline: Agriculture



Most commercial hybrids of indica rice are based on a wild abortive (WA) source of cytoplasmic male sterility (CMS). This cytoplasmic uniformity could lead to genetic vulnerability to disease and insect pests. There is thus an urgent need for cytoplasmic diversification of the male sterility source for hybrid rice breeding.
