摘　　要：从Ｗ６１１１Ｓ × ＣＹ８５－２６及安农Ｓ－１× ＣＹ８５－２６的稳定不育株群体中，观察其育性表现。由安农Ｓ－ １转育的株系育性比较稳定，单株之间差异较小；而由Ｗ６１１１Ｓ转育的株系，花粉育性差异大，且单株之间育性有分离，说明其育性不是很稳定。The fertility of stable sterile plants from W6111S×CY85-26 and An-Nong S-1 × CY85-26 Was observed. The sterility of the line transferred from An-Nong S-1 was rather stable, and the difference between individual plants was very little. However, the fertility of pollens in the line transferred from W6111S differed greatly, and fertility segregation occured among individual plants, indicating that its sterility is not stable.
