Heterosis and maternal effects for seed-oil content were analysed in a set of crosses between agronomically promising and high-oil parents. Small amounts of positive and negative heterosis were observed for seed-oil content in the crossed (maternal) seed. Array means revealed strong maternal influence of the agronomic parents on seed index. The gca and sca components of variance were highly significant for oil percentage.
