A yellowish brown‐seeded Brassica alboglabra was resynthesized from a ( B. alboglabra × Brassica carinata ) × B. alboglabra cross, followed by self‐pollination. The resynthesized B. alboglabra lost the allele of the isozymic locus glucosephosphate isomerase‐2 ( GPI‐2 ) from natural B. alboglabra , which was replaced by an allele from the corresponding genome in B. carinata. A simple Mendelian segregation of these two alleles was observed in the F 2 population of a natural × resynthesized B. alboglabra cross. Furthermore, these two alleles segregated independently from the seed colour.
