结果表明：萍乡显性不育水稻带有质核互作不育系的恢复基因，不同遗传背景的萍乡显性核不育水稻对质核互作不育系具有不同的恢保关系；萍乡显性核不育基因与质核互作不育基因是独立发生的，当质核互作不育系中细胞质和细胞核的隐性不育基因一起作用时，能够掩盖萍乡显性核不育基因的育性表达 The results showed that Pingxiang dominant CMS lines with restorer genes of CMS and CMS lines of Pingxiang dominant CMS lines had different restorer relationships with each other. Pingxiang dominant The sterile gene interacts with the nucleus. The sterile gene plays an independent role. When the cytoplasm and the recessive sterility gene in the nucleus interact with each other in the intersubspecific CMS, it can hide the phenotype of the male sterile gene in Pingxiang Sexual expression
