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.

The oleic, linoleic, and linolenic acid content of rapeseed (Brassica napus L.) oil was investigated in self- and cross-pollinated seed on parental lines and reciprocal F1 populations. The seed was derived from three strains of rapeseed that produce seed oil practically free of eicosenoic and erucic acids. A definite maternal genotype effect on the oleic and linoleic acid content of the cross-pollinated embryo was evident in two of three combinations. Embryo control for the quantities of these two fatty acids was indicated for the third combination. Both embryo and maternal genotype control of linolenic acid content was indicated. There were no cytoplasmic effects evident in the reciprocal F1 populations for any fatty acid in all three combinations.

Low Linolenic

The F2 progeny (64 individuals) from the cross between oilseed rape (Brassica napus L.) cultivar Topas and R4 (a low linolenic mutation line) was analyzed with 8 RFLPs and 34 RAPDs to discover a genetic tag for gene(s) affecting linolenic acid concentration. According to variance analysis (ANOVA), one RAPD marker (25a) was significantly associated with linolenic acid content; the linolenic acid concentration in the seeds of F2 individuals showing the marker (includes both homo- and hetero-zygotes) was 7.43 ± 1.35% and in those lacking the marker was 5.70 ± 1.52%. Marker 25a may be used to facilitate selection for fatty acid composition in future breeding programs of oilseed rape.Key words: Brassica napus, RFLP, RAPD, linolenic acid.

Heritability Estimates

The fatty acid composition of rapeseed (Brassica napus L.) oil was investigated in parental, F1 and F2 plant populations of three crosses among three low erucic acid lines differing in oleic, linoleic and linolenic acid content. The F1 plant population values indicated that the oleic and linoleic acid contents were controlled by a simple additive gene system in one cross. In the other two crosses, partial dominance for high oleic and low linoleic content was observed. Dominance of low linolenic acid values was observed. The heritability estimates for oleic and linoleic acid were similar within each cross. The heritability estimates ranged from 53 to 78% for oleic, 40 to 84% for linoleic and 26 to 59% for linolenic. The estimates of minimum number of effective factors controlling oleic, and linoleic were similar within each cross. The number of effective factors ranged from 2 to 6 for oleic, 3 to 5 for linoleic, 0 to 4 for linolenic. The similarity of genetic behavior of oleic and linoleic acid content within each cross and the very high negative correlation between these components suggests that the relative ratios of oleic and linoleic acid content may be under the control of one genetic system.
