Using this system, the cytoplasmic-genetic male sterile lines were classified into 5 groups, characterised by relative frequency of the different classes of pollen grains. These cytoplasmic-genetic male sterile lines were grown during 6 seasons (1984 and 1985 wet, 1986 and 1987 dry and wet) to study the stability of pollen sterility. Six cytoplasmicgenetic male sterile liens (V 20 A, Zhenshan 97 A, IR 54753 A, IR 54754 A, IR 54757 A and IR 54758 A) having wild abortive type cytoplasm were found to be stable for pollen sterility.
