一般普通小麦品种与节节麦间存在杂交不亲和性。本期试验所用4个普通大麦品种与节节麦的杂交结实率均为0。但采用辐照母本花粉的方法,有4个杂交组合成功地获得了结实率为2.4%—5.6%的杂交种子,表明辐照母本花粉蒙导法能有效地克服普通小麦×节节麦的杂交不亲和性。 There is hybrid incompatibility between common wheat varieties and nodules. In this study, four common varieties of barley and nodular hybrid seed setting rate were 0. However, with the method of irradiating female parent pollen, four hybrid combinations successfully obtained the hybrid seed with the seed setting rate of 2.4% -5.6%, indicating that the pollen dominance method of the irradiated parental pollen can effectively overcome the effects of the common wheat × nodular Of hybridization incompatibility.
