根据花粉粒外壁与柱头表面识别蛋白在授精过程中相互识别的先导作用机制,用足使花粉失活但同时能保持其外壁识别蛋白功能的~(60)Coγ射线40和60Gy 辐照两个普通小麦品种的花粉,并将辐照过的普通小麦花粉与四倍体小麦花粉混合授在普通小麦植株上。结果在原来表现不亲和(结实率为0)的普通小麦×野生二粒小麦的杂交组合中,成功地获得了结实率(6.5%—7.9%)和种子质量与原来表现亲和的普通小麦×四倍体小麦杂交组合基本相同的杂交种子,表明辐照母本花粉蒙导远缘杂交亲和可能是克服小麦远缘杂交不亲和性的一条简便有效的途径。 According to the preferential mechanism of pollen grains’ outer wall and stigma surface recognizing proteins recognizing each other during the process of insemination, 60Co γ-rays of 60Co and 60Co γ rays were used to irradiate two common Wheat varieties of pollen, and the irradiated ordinary wheat pollen and tetraploid wheat pollen on the grant of wheat plants. Results The seed setting rate (6.5% -7.9%) and the common wheat with the same seed quality as that of the original performance wheat were successfully obtained in the cross combination of common wheat × wild mongolian wheat, which was originally incompatible (seed setting rate was 0) × tetraploid wheat hybrid combinations, indicating that hybridization of distant parental hybrids with pollen parental pollen may be a convenient and effective way to overcome the incompatibility of distant hybridization in wheat.
