Using logistic model, regression equations were established as followed: y=12.084 8/［1+exp (6.372 5-0.367 5x)］ and y=91.017 0/［1+exp （18.448 8-0.788 8x）］, which was used to evaluate the responses of maize inbred lines to head smut resistance.

采用逻辑斯蒂模型分别建立了抗、感自交系可溶性糖含量与田间发病率的一元曲线回归方程：y=12.084 8/［1+exp (6.372 5-0.367 5x)］和y=91.017 0/［1+exp（18.448 8-0.788 8x）］，以此建立了以接菌幼苗可溶性糖含量为指标的抗性评价方法，并用于未知抗性种质资源的鉴定。

The objectives of the research were to screen molecular markers of sorghum resistant gene to the physiological strain No.3 of head smut with SSR. Bulked Segregation Analysis was applied in the study. Two segregation populations, restorer line population R population 2381R/Aisi and maintain line population Tx622B/7050B, were used in the research. The amplification bands of 94 pairs primers from 109 ones were clear and stable.
