摘 要 ：从若干方面初步研究了玉米YII-1型不育细胞质与3个主要类群的不育胞质（T、C和S）间的差异。育性恢复测验表明，YII-I胞质有其独特的恢复基因，在各类自交系核背景下，其育性表现与众不同。恢复基因至少有二对，其中一对与C群不育系有别。小斑病菌测试效应，说明YII-1型不属于T群，而线粒体DNA(mt DNA)的电泳图谱说明YII-I胞

Abstract:The differences between YII-I-type male sterile cytoplasm (cms-YII-I) and the three main groups of Cms in maize (S.C.T) have been studied in different ways. Tests in pattern of fertility restoration exhibit that cms-YII-I has its unique restorer genes for the fact that in gave distinct male-fertile
