Abstract Thirty Brassica napus lines have been developed through interspecific hybridization of B. oleracea and B. campestris lines with defined S-allele constitutions. These lines, which represent 29 different S-allele combinations, were tested in a diallel of test-pollinations to determine the activity of the introgressed S-alleles and intergenomic dominance relationships. Some consistent trends were observed: B. oleracea S-alleles high in the dominance series (e.g. S8, S14, S29) were always active in the resynthesized B. napus lines, whereas recessive S-alleles (S2, S15) lost their activity in some test combinations. The B. campestris S-alleles were active in most cases, although 2 alleles were partially inactivated by the recessive B. oleracea allele S15.
