| Abstract: | Summary Strong indication was found for the existence of a chromosal monogenic dominant male sterility-gene in chenese cabbage. This source of male sterility can be of practical use for the production of hybrid varieties. A pronounced drawback is the required removal, in the breeding and seed production stage, of the approximately 50% male fertile plants from each offspring of male sterile plants. Fortunately this removal is facilitated by the penomenon of apical dominace in the flowering process in the whole Brassica rapa taxon. Moreover an advantage of dominant monogenic male sterility is its easy and rapid introduction into all available genotypes of chinese cabbage. |
