Three determinate (dt1/dt1) soybean (Glycine max (L.) Merr.) lines: Hoyt, HC 80-1742 and HC 80-1756, with a "standard" linolenic acid content (Fan/Fan) were crossed to the indeterminate (dt1/dt1), "low" linolenic acid (fan/fan) line G-LLA-F3. The F2 plants descended from these crosses were grown in the field at Harrow in 1988 and the F2:3 plants were grown at Harrow and Ridgetown, Ontario in 1989. In the F2 progeny, the mean linolenic acid content of the determinate plants was not different from the mean of the indeterminate plants for the "standard" class (8.5 and 8.6%) or for the "low" class (4.1 and 4.2%). In the F2:3 progeny, for the "standard" class, the determinate plants (9.4%) had a significantly (P < 0.05) higher mean linolenic acid content than the indeterminate plants (9.1%). For the "low" class, the mean linolenic acid content of the determinate plants (4.9%) was significantly (P < 0.05) lower than the mean of the indeterminate plants (5.2%) at Ridgetown, but was not different (4.7 and 4.7%) at Harrow. The differences in linolenic acid content between stem types were less than the differences between lines or between locations. Overall, there was no pattern associated with stem termination type and linolenic acid content for soybean plants grown in short season areas. Key words: Soybean, Glycine max (L.) Merr., determinate, indeterminate, linolenic acid

Linolenic acid and seed lipoxygenases are associated with off flavours in soybean products. F5 recombinant inbred lines (RILs) from a cross between a low linolenic acid line (RG10) and a seed lipoxygenase-free line (OX948) were genotyped for simple sequence repeats (SSR), random amplified polymorphic DNA (RAPD), sequence-tagged sites (STS), and cleaved amplified polymorphic sequence (CAPS) markers and evaluated for seed and agronomic traits at 3 Ontario locations in 2 years. One hundred twenty markers covering 1247.5 cM were mapped to 18 linkage groups (LGs) in the soybean composite genetic map. Seed lipoxygenases L-1 and L-2 mapped as single major genes to the same location on LG G13-F. L-3 mapped to LG G11-E. This is the first report of a map position for L-3. A major quantitative trait locus (QTL) associated with reduced linolenic acid content was identified on LG G3-B2. QTLs for 12 additional seed and agronomic traits were detected. Linolenic acid content, linoleic acid content, yield, seed mass, protein content, and plant height QTL were present in at least 4 of 6 environments. Three to 8 QTLs per trait were detected that accounted for up to 78% of total variation. Linolenic acid and lipoxygenase loci did not overlap yield QTL, suggesting that it should be possible to develop high-yielding lines resistant to oxidative degradation by marker-assisted selection (MAS).

Single plant selections for high, intermediate, and low oleic, linoleic and linolenic acid content of rapeseed (Brassica napus L.) oil were made in the F2 generation of three crosses. The three parent strains produced seed oil practically free of eicosenoic and erucic acids and differed in oleic, linoleic and linolenic acid content. The F3 and F4 progeny were analyzed for fatty acid composition. Selection for low and high values of oleic and linoleic acid content was reasonably successful in two out of three crosses. Selection for extremes of linolenic acid content was unsuccessful in all three crosses. Regression analyses indicated high heritabilities for oleic and linoleic acids in two of three crosses but low heritabilities for linolenic acid in all three crosses. Correlations between oleic versus linoleic and oleic versus linolenic were negative and highly significant. Correlations between linoleic versus linolenic were of lower magnitude but positive and significant in all but two populations.
