摘要:
Data on stem volume of intra‐ and interprovenance hybrids ofPicea abiesfrom three field trials, 20–28 years of age, are presented. The mating design is factorial in all trials and the two oldest have the same 33 families. The variation in general combining ability of the mother trees was significant at the youngest trial, while that of the father trees was significant at all trials. The variation in specific combining ability was significant in all trials. The variance component for general combining ability was 1.4–3.7 times larger than that for specific combining ability. A strong genotype × environment interaction was noted both for parental general combining ability and family means. The largest gains in breeding will be obtained by producing commercial seed of selected families.
