利用6个T型不育系及其保持系和5个恢复系配制30个T质杂种和30个相应的A质杂种，另外选用4个K型不育系与2个K型恢复系配置8个K质杂种和8个相应的A质杂种，研究杂种F1和杂种F2品质性状的杂种优势。研究结果表明：T质、K质及A质杂种F1和F2的籽粒胚乳蛋白质含量、干、湿面筋含量均表现较强的杂种优势，杂种优势变异范围大，多数组合呈正向优势且具有较高的超亲优势，与前人的结论不一致，说明利用杂种优势提高杂种小麦的籽粒胚乳蛋白质含量、干、湿面筋含量是可能的。T质、K质及A质杂种F1和F2籽粒胚乳的Zeleny沉淀值的杂种优势以负向为主，说明利用杂种优势提高杂种小麦的籽粒胚乳Zeleny沉淀值，提高小麦烘烤品质具有一定困难，但各类杂种都有一定数量组合的F1和F2的Zeleny沉淀值表现一定程度的正向杂种优势，因此通过正确选择亲本组配强优势组合，利用杂种优势提高沉淀值是有可能的。
Six T-type CMS lines and their maintainer lines and five restorer lines were used to prepare 30 T-type hybrids and 30 corresponding A-type hybrids. In addition, 4 K-type CMS lines and 2 K-type restorer lines were used to configure 8 A K hybrid and 8 corresponding A hybrids were used to study the heterosis of F1 hybrids and F2 hybrids. The results showed that the protein content of endosperm, dry and wet gluten content of T, K and A hybrids F1 and F2 both showed strong heterosis, the variation range of heterosis was large, most combinations showed positive and high , Which is inconsistent with previous conclusions. It indicates that it is possible to increase the protein content of the grain endosperm of hybrid wheat by using heterosis, and the dry and wet gluten content is possible. The dominant heterosis of Zeleny sedimentation value of F1 and F2 kernels of T, K and A hybrids was negative, which indicated that it was difficult to improve the Zeleny sedimentation value of wheat endosperm and improve the baking quality of wheat by using heterosis. However, the Zeleny sedimentation values of F1 and F2 in some hybrids show a certain degree of positive heterosis. Therefore, it is possible to increase the sedimentation value by utilizing the heterosis by correctly selecting the parent group for strong heterosis.
