Two new sources of cytoplasmic male‐sterility designated ‘L66A’ and ’L67A’ have been isolated. Genetic‐cytoplasmic interactions for restoration of fertility prove that these sources are different from ‘Tift 23A.’ The maintainers for these sources also maintain sterility in Tift 23A. ‘Tift 23B,’ maintainer for Tift 23A, is a good fertility restorer for L66A and L67A. Good fertility restorers for Tift 23A, such as ‘T239 and ‘L‐4,’ are excellent sterility maintainers for L66A and L67A. L66B, maintainer for L66A, restores fertility in L67A, while L67B is a partial fertility restorer for L66A. Genetic models suggesting the relationship between different sources are presented.
