谷子不同品种对粒黑穗病的抗性差异很大，其中有７９．５％的品种属感病或高度感病类型。谷子抗粒黑穗病的遗传背景十分复杂，遗传方式为多基因控制的数量遗传，遗传力为３７．６６％，超亲遗传比较明显。双亲发病株率平均值和差值与Ｆ２高抗株率呈极显著的负相关，ｒ＝－０．８４４６＊＊和ｒ＝－０．８６３８＊＊。正确选配杂交组合对抗病育种的成败至关重要
Resistance to smut was very different among different varieties of millet, of which 79.5% were susceptible or highly susceptible. Mildew resistance to smut is a complex genetic background, the genetic mode for the number of genetic control of genetics, heritability was 37.66%, super-progeny more obvious. The mean and difference of the rate of parents of the parents was extremely significantly negatively correlated with the rate of F2 high resistant strains, r = -0.8446 ** and r = -0.8638 **. Correct selection of cross combinations is crucial to the success or failure of disease breeding
