摘要：

The inheritance of the low linolenic acid content (derivated from mutant lines) in rapeseed was investigated. Molecular techniques of gene mapping through RAPD markers were applied on a microspore-derived progeny from a high x low linolenic acid Fl hybrid. 'Bulked segregant analysis' made it possible to test rapidly number of RAPD primers. Two linkage groups of 6 markers (72.7 cM and 75.6 cM) were determined. Each corresponded to a major QTL which explained 24% and 30.7% of the total phenotypic variation of the linolenic acid content. It was confirmed that two independant mutations were implied in the low linonenic acid content.
