The One

The interplant outcrossing rate was studied for one cultivar and four lines of rape (Brassica napus) and three cultivars of mustard (Brassica juncea) under field conditions at Saskatoon, Saskatchewan, in 1982, 1983 and 1984. Marker characters used for determining outcrossing rates were seed oil erucic acid content for rape and seed color for mustard. The average interplant outcrossing rate was 21.8% for rape and 18.7% for mustard. No significant differences in outcrossing rates among the one cultivar and the four lines of rape or the three cultivars of mustard were detected. A wide range in outcrossing rates between plants within cultivars and lines was observed for both species, but whether this variation was genetic or was environmentally induced could not be determined in these experiments. Some of the implications of this partial outcrossing on methods used for the breeding of these crops are discussed.Key words: Outcrossing, rape, mustard

Backcross Populations

Genetic analysis of F2, F3, and backcross populations supported the hypothesis that erucic acid content in seed oil of plants of Brassica napus L. is governed by two genes displaying no dominance and acting in an additive manner. Environment appeared to influence erucic acid content, especially in genotypes capable of producing a large amount of this acid. Methods for the breeding of plants of Brassica campestris L. with zero erucic acid are outlined and it is suggested that similar methods could be used to breed for or against other fatty acids.

Selection Of

Erucic acid is the major and characteristic component of common rapeseed oils. Seed oils from a total of 125 strains from three species of Brassica (B. napus L., B. campestris L., and B. juncea (L.) Coss.) grown near Winnipeg in 1959 were analysed for erucic acid content. The range of variability for this component was similar to the range of previously reported values. Analyses of seed oils from individual plants revealed a greater range of variability and repeated selection resulted in isolation of rape strains (Brassica napus L.) from two different sources with seed oils containing only traces of erucic acid. Oleic has replaced erucic acid as the major constituent of these oils. Analysis of F2 data indicated that inheritance of erucic acid content is conditioned by two independent gene loci and that the dosage effect of the genes is additive. Pollen source exerts a direct effect on the composition of the oil (xenia effect).
