A narrow genetic base has hindered improvement of Brassica juncea(A^(j)A^(j)B^(j)B^(j)).In this study,large-scale genomic components were introduced from diploid ancestor species into modern *** using a digenomic hexaploid *** hexaploids A^(j)A^(j)A^(r)A^(r)B^(j)B^(j) and A^(j)A^(j)B^(j)B^(j)B^(n)B^(n) were first developed from ***×***(A^(r)A^(r))and ***×***(B^(n)B^(n)),and then crossed with dozens of *** and ***,*** types of hexaploid showed high pollen fertility and moderate seed set throughout the S_(1) to S_(3) generations,and could be crossed with diploid progenitor species under field conditions,in particular for the combination of A^(j)A^(j)B^(j)B^(j)B^(n)B^(n)×*** A^(j)A^(r)B^(n)B^(j)-type and 31 A^(j)A^(r)B^(n)B^(j)-type *** resources were generated,of which the A^(j)A^(r)B^(n)B^(j) type showed higher *** these new-type *** resources,97 individual plants were genotyped with 42 simple sequence repeat markers,together with 16 current *** accessions and 30 hexaploid *** on 180 polymorphic loci,the new-type *** resources and current *** were separated clearly into distinct groups,with large genetic distance between the new-type *** resources and current *** study provides a novel approach to introducing large-scale genomic components from diploid ancestor species into ***.
