摘　　要：利用回交方法，探讨了Ｔａｌ小麦细胞质对Ｆ２株高、穗长、穗粒数、千粒重等主要农艺性状的遗传效应。结果表明．Ｔａｌ小麦细胞质对其Ｆ２主要农艺性状无不良的遗传效应，对粒色的遗传亦无影响，与普通小麦细胞质相比在遗传上基本上是同质的。In this experiment the method of backcross was used to evaluate genetic effects of Tal wheat cytoplasm on plant height, spike length, kernel number of the main spike, 1000-kernel weight etc. of Tal F2. The results showed that the Tal cytoplasm in comparison with the normal ones of common wheat had no deteriorative genetic effects on the most of agronomic characters of Tal F2. It had no influence on genetics of kernel color too. The Tal wheat cytoplasm and the normal ones, was agreeable on genetics.
