Phenotypic male sterility
WebMale sterility mainly includes three types, i.e., cytoplasmic male sterility (CMS) caused by both mitochondrial and nuclear genes, genic male sterility (GMS) caused by nuclear genes alone, and photoperiod- and/or temperature-sensitive genic male sterility (2–4).Among them, the CMS-based three-line system has been successfully used for hybrid seed …
