S-a, S-b and S-c are three loci for F1 pollen sterility in cultivated rice （Oryza sativa L.）. Taichung 65 （T65） is all Sj/Sj at these three loci, while its F1 pollen sterile near-isogenic lines, TISL2 （S-b）, TISL4 （S-a） and TISL5 （S-c） is Sj/Sj according to their respective sterility locus. Using SSR molecular marker to detect the segregation of the allele Si and Sj in pollen calli population induced from different hybrid F1, which have different pollen sterility locus, showed that the segregation of allele Si and Sj was distorted. The distorted direction of pollen calli population in vitro was not the same as F2 population in vivo. The quantities of pollen callus carrying Sj were much more than that of carrying Siat S-a and S-c locus, the ratio of Si and Sj were 1：4.81 and 1：1.96 respectively. But the opposite tendency was observed at S-b locus, the ratio of Si and Sj being 1：0.35. At the same time, all these results were undisturbed by either culture medium or culture period.

利用活体压片、半薄及超薄切片技术,对栽培稻(OryzasativaL.)花粉不育杂种F1及育性正常的亲本台中65离体培养前后的小孢子及花药壁进行细胞学研究。结果表明:与台中65相比,杂种F1的花粉小孢子在发育至单核中-晚期,出现比例较高的胞质凝聚小孢子和少量星型小孢子,正常小孢子和淀粉化小孢子比例降低。在离体条件下,胞质凝聚小孢子、星型小孢子、正常小孢子、液泡化小孢子、淀粉化小孢子的发育主要沿着胞质凝聚败育过程、孢子体发育过程、配子体发育过程、液泡化过程和淀粉化过程进行;药壁组织在离体条件下,杂种F1比台中65的绒毡层降解速度快,中层膨大程度高。杂种F1与台中65在离体培养下小孢子发育及药壁细胞学的差异主要是受到S-a座位内等位基因互作及离体培养环境的影响。
