选用了42个普通小麦品种、9个品种间杂种 F_1和一个 F_2作母本,分别与苏联球茎大麦和匈牙利球茎大麦及其不同株系杂交,其中的部分品种还同黑麦进行了杂交,以研究小麦与球茎大麦的可杂交性及其遗传规律。结果表明,小麦与球茎大麦的可杂交性同小麦与黑麦的情况相似,供试的两个球茎大麦及其株系间在可杂交性上无显著差异存在。授粉后喷射赤霉酸能提高易杂交品种的杂交率和促进胚的发育,但对不能杂交的品种无效。结果还表明可杂交性受一对基因支配,易杂交为隐性,不易杂交为显性,显性程度随小麦品种不同而异。根据试验结果和有关研究,作者认为,除非能把易杂交基因代换进大部分小麦品种中去,或能找到易与多数小麦品种杂交的球茎大麦,否则,球茎大麦技术不可能在小麦育种上广泛应用。作者推测,小麦与球茎大麦和黑麦的可杂交性在很大程度上是由小麦的同一遗传系统控制的,并认为小麦与这两个种的可杂交性相似是由于黑麦和球茎大麦有着较密切的亲缘关系而表现出的同源变异。
42 common wheat cultivars, 9 F1 hybrid F1 and F2 F2 were selected as the female parents, which were crossed with the Soviet corms barley and the Hungarian bulblets barley and their different lines, and some of them were also crossed with rye to Study on the Hybridization and Inheritance of Wheat and Bulblet Barley. The results showed that the hybridization between wheat and bulblets was similar to that of wheat and rye. There was no significant difference in the hybridity between two bulblets and their strains. Spraying gibberellic acid after pollination can improve the hybridization rate of hybrids and promote the development of embryos, but it is ineffective to the hybrids. The results also show that hybrids are dominated by a pair of genes, hybrids are recessive, not hybrids dominant, dominance varies with wheat varieties. According to the experimental results and related studies, the authors argue that bulbul barley technology can not be used on wheat breeding unless it can be substituted for most of the wheat varieties, or bulbous barley that can be easily crossed with most wheat varieties widely used. The authors speculate that the hybridization of wheat to bulbous barley and rye is largely controlled by the same genetic system of wheat and that the hybridization of wheat with these two species is similar to the one with rye and bulblets of barley Closer genetic relationship and showed homologous variation.
