以来自粟不同生态区（东北平原、华北平原、内蒙古高原和黄土高原）２２份优异种质进行对白发病菌〔Ｓｃｌｅｒｏｓｐｏｒａｇｒａｍｉｎｉｃｏｌａ（Ｓａｃ．）Ｓｃｈｒｏｔ．〕２０个生理小种６８个菌株抗谱的测定，同时用各生态区菌株对本区粟品种进行抗性关系的研究，其中抗５０％小种的品种有３３２、龙谷２５变、张农１２、大红袍、大同北郊、七月黄、大青苗、紫杆黄谷和西城白９个，具有广谱抗性而在本生态区亦表现抗病性强的品种有３３２、龙谷２５变、张农１２等，选出的广谱抗性品种将为粟抗白发病育种、优良品种的合理布局及抗性机理的深化研究提供了基础材料。
A total of 22 elite Germplasm resources (Sclerospora graminicola (Sac.) Schrot) were collected from 22 different germplasms in different ecological regions (Northeast Plain, North China Plain, Inner Mongolia Plateau and Loess Plateau) Antibiotic resistance of 68 bacterial strains of 20 physiological races was tested. At the same time, the resistant strains of the cultivars were studied by using the strains from different ecotypes. Among them, 332 varieties resistant to 50% races, 25 varieties changed from Longgu, Dahongpao, Datong northern suburbs, July yellow, Daqingmiao, Zizhuang yellow valley and Xicheng white 9, with broad-spectrum resistance in the ecological zone also showed strong disease resistance 332, Valley 25 , Zhang Nong 12, etc., the selected broad-spectrum resistant varieties will provide the basic materials for mildew resistant white disease breeding, rational distribution of fine varieties and the deepening of the resistance mechanism.
