小麦病毒病是我省北部冬麦区常发性的严重病害。如1967年延安榆林两地区大发生,发病麦田123万亩,失收面积43万亩。据陕西省植保所和本所研究,小麦病毒病主要包括叶跳蝉所传“红矮”、“兰矮”,灰飞虱所传“丛矮”及麦蚜所传“黄矮”等类型,群众把前三类统称“寸钵”。现将我所20多年来的抗病毒育种工作的体会整理如下,以供商讨。一、抗病品种的生理生态特性与亲本选择抗病育种缺少方法、资料可鉴,国内农家品种又多不抗病。我们通过引进国外品种进行鉴定,发现一些品种表现高抗或耐“寸

Wheat virus disease is a common serious disease in the winter wheat area in the northern part of our province. Such as the 1967 Yulin, Yan’an occurred in two areas, the incidence of 123 million mu of wheat fields, loss of area of ​​43 mu. According to research by Shaanxi Provincial Institute of Plant Protection and the Institute, wheat virus diseases mainly include the types of “red dwarf”, “blue dwarf”, “dwarf” and “yellow dwarf” The masses referred to the former three categories as “inch bowl.” Now I have more than 20 years of experience in anti-virus breeding work organized as follows for discussion. First, the physiological and ecological characteristics of resistant varieties and their parents Select disease-resistant breeding methods, information can be learned from the domestic farmers are not resistant to many varieties. We have been identified by introducing foreign varieties and found that some varieties show high resistance or resistance
