Research results have shown that two restorer loci Rfl and Rf2 are involved in the restoration of CMS- T, a single restorer Rf3 for the restoration of CMS-S and 3 genes involved in CMS-C restoration. The molecular study on CMS of maize indicated that the mechanism of S-CMS and C-CMS were more complicated than that of T-CMS. The paper also discusses the progress on the utilization of male sterility in China and in USA and points to the use of six methods to utilize ms in maize breeding. However, the authors believe that the most important and potential methods in seed production are photoperiod sensitive male sterility and engineered male sterility. In the end, the paper presents discovery and primary study on the photoperiod sensitivity in maize. Some preliminary results indicate that CA-507's fertility was photoperiod sensitive and that two pairs of genes are involved in controlling sensitivity to photoperiod.Collection: CIMMYT Publications Collection
