【Abstract】 The results showed that there was significant difference in the anther development between the cytoplasm male sterile line and maintain line of Chinese cabbage. The maintain line 92 19 1 5 1 in the anther development is the same as the uaual anther. The anther development of male sterile line T92 1 1 1 A was blocked without anther at the stage of archesporial cell. Also, the few pollons were observed.更多还原
