70年代初,我国应用以3197A为抗源的高粱杂交种后,高粱产区的丝黑穗病情得到缓解,但几年后发病率又有回升,且发展很快。到80年代初,由于新抗源ATX622的引进及其杂交种在生产上的推广应用,再次控制了丝黑穗病的发生。因此,利用抗源选育抗病品种,是防治丝黑穗病最经济有效的措施。为了从我国丰富的高粱品种资源中筛选 In the early 1970s, after the application of sorghum hybrids with 3197A as the source of resistance, the occurrence of smut in sorghum producing areas was alleviated. However, the incidence of mosquitoes increased again after a few years and developed rapidly. By the early 1980s, the occurrence of head smut was again controlled by the introduction of the new anti-ATX622 source and its popularization and application in hybrid production. Therefore, the use of resistant varieties breeding disease-resistant varieties, is the most economical and effective measures to prevent head smut. In order to select from abundant sorghum variety resources in our country
