| Abstract: | Summary F1 behaviour and F2 variation in disease reaction were studied in the interspecific cross Brassica juncea x B. napus. Gene(s) for adult resistance to blackleg (Leptosphaeria maculans) were found to be present in the A genome of B. juncea and could be transferred to B. napus. Gene(s) for complete (seedling plus adult) resistance in B. juncea appeared to be located in the B genome. The chance of their transfer to the oilseed rapes (B. napus or B. campestris) would therefore seem to be remote. |
