91FS是一个稳定遗传的籼粳杂种水稻新型不育突变体，育性特征表现为，雌雄配子和受精过程正常，约25%的受精卵发育成胚，约75%的受精卵终止发育，与91FS 群体约25%的结实率吻合，而且六代保持不变；91FS的RAPD和RFLP的谱带六代保持稳定和一致，与91FS的杂种性状和育性表达的稳定性也是吻合的；91FS与籼粳杂种可育材料91FM和以 91 FS为父本的杂交F1代（D297A × 91FS）材料的RAPD比较分析表明，91FS与CK相比表现出广泛的DNA多态性和同一性，同时也表现出特异的新带和一些缺失谱带，其多态性、同一性和特异性是可遗传的. 图4 表1 参15

The fertility characteristic of 91FS, a new heritable Indica-japonica rice hybrid sterile mutant, displayed its normal female/male gametes and f ertilization process. About 25% of the fertilized eggs could develop into mature embryos while about 75% of the fertilized eggs stopped further developing, whic h coincided with the population seed percentage of 91FS. In addition, this featu re kept constant within six generations. The stability and consistency of 91FS R FLP bands coincided with the stability of hybrid characteristic and fertility ex pression. The RAPD results of 91FS, 91FM(a fertile Indica-japonica rice hyb rid) and F1(D297AX91FS) showed that there were quite different kinds of DNA po lymorphism among 91FS and the other two controls. 91FS also displayed some new s pecial DNA bands and absent bands. The polymorphism, identity and specificity of 91FS are heritable. Fig 4, Tab 1, Ref 15
