The results showed that a pair of sterile genes were present in L17A and Shan 2A and three pairs of recessive sterile genes in GCDA-1; however, linkage seemed to exist between the CMS gene s 1 and the GMS gene m 1 or m 2.

• 结果表明，L17A和陕2A为1对隐性不育基因控制，双重不育系由3对隐性不育基因所控制，但胞质不育基因s1与两个核不育基因m1m2中的一个可能存在连锁关系。
