Abstract:

Research is in progress in China, at IRRI, and elsewhere to diversify sources of cytoplasmic male sterility (CMS) in rice.

To study gene action in high-yielding rice varieties of diverse origin, 13 genetically distinct parents were selected from nine clusters, comprising 56 rice genotypes of different ecogeo-graphic origin, formed through Mahalanobis D2 statistics. Selected parents were subjected to full diallel crosses and F15 plants were raised. Observations were taken on yield components.
