【Abstract】 The selecting process, morphological characteristics and main characters as well as the inheritance of male sterility of barley nucleo cytoplasmic male sterile line 96f 7A are reported. The results showed that 96f 7A had relatively good agronomic traits, and was a two rowed , husked and glumes opening and flowering barley with thin light yellow or white and thoroughly abortive anther without both splitting and dispersing pollen. The male sterility of 96f 7A was controlled by a pair of recessive genes. The abortive cytoplasm of 96f 7A originated in two rowed barley landrace from Sichuan of China, while the male sterile genes in cell nucleus were resulted from the naturally recessive mutation of the fertile genes in cell nucleus of this landrace.更多还原
