Abstract excerpt
Interspecific hybridization is a significant evolutionary force as well as a powerful method for crop breeding. Partial substitution of the AA subgenome in Brassica napus (A(n) A(n) C(n) C(n) ) with the Brassica rapa (A(r) A(r) ) genome by two rounds of interspecific hybridization resulted in a new introgressed type of B. napus (A(r) A(r) C(n) C(n) ). In this study, we construct a population of recombinant inbred...
