For most cruciferous plants, which are known as important crops and a number of weeds, hybrid breeding is hampered by the unavailability of a pollination control system. Male sterility induced by a gametocide can be useful for the utilization of plant heterosis. The gametocidal effect of
Protoplast fusions between Brassica napus and Orychophragmus violaceus for transfer of valuable traits to oilseed rape resulted in 257 somatic hybrid plants. Hybridity was confirmed by morphological, cytological and molecular means. Symmetric fusions gave rise to 131 plants. Fifty eight of these
Alien chromosome addition lines have been widely used for identifying gene linkage groups, assigning species-specific characters to a particular chromosome and comparing gene synteny between related species. In plant breeding, their utilization lies in introgressing characters of agronomic value.

One and three male sterile plants were found in the progenies of the intergeneric hybrids by crossing Brassica napus and Brassica juncea to Orychophragmus violaceus, respectively. After interspecific cross and full-sib crosses, four genic male sterile lines were obtained. The results of cytological
BACKGROUND The gynoecium is one of the most complex organs of angiosperms specialized for seed production and dispersal, but only several genes important for ovule or embryo sac development were identified by using female sterile mutants. The female sterility in oilseed rape (Brassica napus) was
