１９９３～１９９６，以Ｔ型不育系、保持系和恢复系为材料，对影响Ｔ型杂种小麦种子质量及其稳定性的核质因素进行了研究。结果表明，多数不育系种子的粒重和发芽率仅分别相当于保持系的９０％和５０％左右，年份间的变异较大；有些不育系种子的发芽率在年份间的变异系数高达２３．７％。只有极少数不育系的种子质量与保持系基本相同，且稳定性较好。不育系种子的皱缩程度和发芽率在基因型间存在极显著的差异。不育系和恢复系杂交产生的杂交种子，其粒重主要取决于不育系，发芽率则与双亲都有关系，当不育系种子的的发芽率在７０％以上时，杂交种的发芽率与双亲发芽率的乘积呈高度正相关，ｒ＝０．８５０＊＊。正反交试验表明，恢复基因可以有效地消除Ｔ型胞质对种子质量的负效应。普通小麦中的非恢复基因也能有效地抑制Ｔ质对种子发育的不良效应，但这类基因的频率很低，其遗传规律尚需进一步的研究。
From 1993 to 1996, T-type sterile lines, maintainer lines and restorer lines were used as materials to study the nuclear factors affecting the quality and stability of T-hybrid wheat seeds. The results showed that the seed weight and germination rate of most CMS lines were only about 90% and 50% of the maintainer lines, respectively, and the variation among years was larger. The coefficient of variation of the germination percentage of some CMS lines was as high as 23.7%. Only a few germplasm lines have the same seed quality and maintainer line with better stability. The degree of shrinkage and the rate of germination of CMS lines were significantly different among genotypes. The seed weight of the hybrid seed produced by the crosses of CMS and restorer lines mainly depends on the CMS and the germination rate is related to both parents. When the germination rate of the sterile seed is above 70%, the hybrid seed germination The rate was positively correlated with the product of the parents’ germination rate, r = 0.850 **. The reciprocal crosses and crosses showed that the restorer gene could effectively eliminate the negative effect of T cytoplasm on the seed quality. The non-restoring genes in common wheat can also effectively inhibit the adverse effects of T on the seed development, but the frequency of these genes is very low, the genetic rules need further study.
