选用籽粒色泽不同遗传标记材料 ,将白粒玉米 (作母本 )花粉与紫粒玉米 (作父本 )花粉以及黄粒高油玉米 (作父本 )花粉大致以 1:1:1混合的授粉方式 ,研究玉米油分基因花粉直感效应。结果表明 ,普通玉米间杂交 ,籽粒含油量变化不大 ,因组合而异。用高油玉米作父本给普通玉米授粉 ,因高油玉米花粉直感效应 ,可显著提高杂交当代籽粒含油量。据试验估计 ,用高油玉米自交系为材料做授粉亲本 ,花粉直感效应值为 0 .35～ 0 .38,用高油单交种为材料做授粉亲本 ,花粉直感效应值为 0 .36～ 0 .4 8
The genetic marker materials with different grain color were chosen to pollinate the pollen of white grain maize (as the female parent) and purple grain corn (male parent) pollen and the yellow grain tall oil corn (male parent) pollen roughly in a ratio of 1: 1: 1 Way to study the direct effects of pollen in maize oil gene. The results showed that there was little change in the oil content of common maize and the combination of them. Using high-oil corn as the male parent to pollinate common corn, the direct oil effect of high-oil corn pollen can significantly increase the oil content of hybrid contemporary grain. According to the experimental estimation, the inbred lines of high-oil maize were pollination parents, the direct effect value of pollen was 0.35-0.38, pollination parents were made with high oil single cross-pollination materials, and the direct effect value of pollen was 0.36 ~ 0 .4 8
