Abstract:Reducing the content of linolenic acid to improve soyabean (Glycine max) oil quality is a desirable breeding objective. An F2 population derived from a cross between a low linolenic mutant, C1640 (fanfan), and a high linolenic accession, PI479.750 (FanFan) was used to map the Fan locus. This recessive allele fan controls the 18:3 linolenic acid content in C1640. Because linolenic acid seemed to be inherited as a quantitative trait in this cross, MAPMAKER-QTL was used to place Fan close to RFLP markers pB194-1 and pB124 on linkage group B2. Localization of this locus to the soyabean genetic map may be useful for molecular biologists interested in cloning the gene or for geneticists interested in identifying modifying genes.
