The goal of this study was to determine the feasibility of maintaining or increasing the oil content of oats ( Avena sativa L.) while decreasing polyunsaturated fatty acid concentration. The F 1 and F 2 populations from crosses between dissimilar parents were analyzed for groat oil percentage and for fatty acid composition. Inheritance patterns for linolenic acid suggested additive genetic control while oleic and linoleic acids were each controlled, in part, by a partially dominant gene or genes. Both additive and dominance gene action were observed for oil concentration. Cytoplasmic influence on fatty acid composition was not evident in reciprocal F 1 populations but was suggested by F 2 population analysis. Heritability estimates for the various fatty acids ranged from 49.3 to 79.8%. Oleic acid percentage was positively correlated with oil concentration while linoleic and linolenic acid correlations with oil level were negative. The breeding objective of lowering polyunsaturate concentration as a percentage of oil may be readily attained; however, if concentration as a percentage of grain is used, success seems less likely.
