摘　　要：该研究利用6个亲本按Grifffing方法2配制了一套完全双列杂交组合,探讨了小麦品质性状的杂种优势,认为除单株蛋白产量和醇溶液蛋白相对含量外,所有品质性状的平均超亲优势均为负值,但它的变化范围较大,选出强优势组合的可能性是存在的。Aoset of diallel crosses involing six wheat (T rltlcum aestlvum) parents, according to the random model of quality characters, The results were as follows The average superparent heteroses of F_1 hgbrids for all quality characters were negative except grain protein yield per plant and gliadin content per 100 gram protein, but the range of variation in heteroses were very large. This means that high positive heteroses could be found in breeding practice.
