Hexaploid-bridged introgression broadens genetic diversity and enriches clubroot-resistance alleles in Brassica juncea

IntroductionThe narrow genetic base of current Brassica juncea (AABB) has limited the genetic improvement of this crop.MethodsIn this study, we developed novel germplasm by crossing synthetic hexaploid bridge lines (AABBBB and AAAABB) with diploid progenitors B. rapa (AA) and B. nigra (BB), followed...
