Microspore culture reveals high fitness of B. napus-like gametes in an interspecific hybrid between Brassica napus and B. oleracea.
The strategies of crossing B.napus with parental species play important role in broadening and improving the genetic basis Joint Care of B.napus by the introgression of genetic resources from parental species.With these strategies, it is easy to select new types of B.napus, but difficult to select new types of B.rapa or B.oleracea by self-pollinati
