小麦品种与球茎大麦的可交配性在品种间差异显著,此种差异与品种来源的地区无明显的关系。小麦杂种F_1的可交配性大多比其可交配性低的亲本品种有所提高。不亲和的Hope等品种与亲和性高的“中国春”等品种的杂种F_1与球茎大麦杂交时表现亲和。除Kr显性基因外,尚有其他基因控制小麦与球茎大麦的可交配性。选择与小麦可交配性高的球茎大麦为父本,可以提高小麦同球茎大麦的杂交结实率。 The cross-fertility of wheat cultivars and bulblets of barley was significantly different among the cultivars. There was no significant relationship between the cultivars and the cultivars. Most of wheat F1 hybrids had higher mateability than their low mateability parents. Inbred Hope and other varieties and high affinity “Spring” and other varieties of F1 and hybrid barley barley showed affinity. In addition to Kr dominant genes, there are other genes that control wheat and bulb barley malleability. Selection and wheat compatibility of bulbs of barley as a male parent, can improve the wheat and bulbous barley seed setting rate.
