Abstract

Raising the energy content of oat (Avena sativa L.) groats by increasing their oil percentage could improve the economic value of oats as a feed grain and as a source of culinary oil. Relative importance of genotype x environment interaction for groat-oil content and grain yield and the correlations of groat-oil content with yield and maturity were evaluated for ten cultivars grown at three Iowa locations for two years. Cultivar x location mean squares were significant for both traits, but they were much smaller, relative to cultivar mean squares, for groat-oil content than for grain yield. Ranking of oat cultivars for groat-oil content was similar in all environments. Groat-oil content was positively correlated with grain yield in both years (r = 0.62* and 0.63*) and had a negative but nonsignificant correlation coefficient with maturity (r = - 0.28 and - 0.48). These relationships are favorable for the development of high-yielding, high groat-oil content cultivars.
