摘要
以１６个品质性状不同的普通小麦品种及其双列杂交的Ｆ１为材料，对品质性状杂种优势强优势组合选配规律进行了研究。结果表明，品质性状的杂种优势要低于农艺性状，各品质性状杂种优势表现不完全一致，多随双亲性状水平的提高而减少，以品质性状表现值均为中等的双亲进行杂交其Ｆ１的杂种优势值最高。干面筋含量可通过高双亲杂交而使杂种Ｆｌ得到改善。
? With 120 hybrids from a 16×16 diallel crosses and their parents, the studies on the heterosis of 4 quality characters of winter wheat were carried out. The results were as follows. The heterosis value of quality characters was higher than that of agronomy characters. The heterosis of quality characters decreased as the character values of parents increased. The crosses between parents with mid-value characters had the highest heterosis over mid- parent and the check. The dry gluten contents in F1 hybrids would be improved through crosses between parents with the higher values.
