A recessive epistatic genic male sterile two-type line, 7365AB (Bnms3ms3ms4msRrfRf/BnMs3ms3ms4ms4RfRf), combined with the fertile interim-maintainer 7365C (Bnms3ms3ms4ms4rfrf) is an effective pollination control system in hybrid rapeseed production. We report an effective strategy used to fine map BnMs4 and BnRf. The two genes were both defined to a common(More)
7365AB, a recessive genetic male sterility system, is controlled by BnMs3 in Brassica napus, which encodes a Tic40 protein required for tapetum development. However, the role of BnMs3 in rapeseed anther development is still largely unclear. In this research, cytological analysis revealed that anther development of a Bnms3 mutant has defects in the(More)
Both the pollination control system and genetic distance are major factors in the utilization of crop heterosis. The recessive genic male sterile line (RGMS) 7-7365A (Bnms3ms3ms4ms4) has been widely applied to hybrid seed production because it can generate a completely male sterile population by crossing with the 7-7365C temporary line (Bnms3ms3rfrf).
