在自然条件下观察小麦品种对于赤霉病抗病力的强弱,常因缺乏病害流行的必要环境而得不到预期结果,影响品种抗病性的研究与选育工作.五十年代,原华东农科所首先用土壤表面接种带菌麦粒和花期喷病菌分生孢子悬浮液等方法,进行小麦品种对赤霉病的抗性鉴定,一直沿用至今.由于病菌子囊壳的形成,子囊孢子的成熟、释放及子囊孢子和分生孢子的传播、侵染与气象条件关系密切,以致品种在田间的感病程度(病穗率与病情指数)因年份、播期及品种生育期早迟而有较大差异.尤其在病害特轻的年份,用病穗率、病情指数的标准,难以评定小麦品种 In natural conditions, the wheat varieties for the scab of disease resistance strength, often due to the lack of disease epidemic and the necessary environment can not get the expected results, affecting the variety of disease resistance research and breeding work.In the fifties, the original East China Institute of Agricultural Sciences first with the soil surface inoculation with wheat and fungi spore suspension of the spore suspension of wheat varieties for the identification of resistance to scab, has been in use so far.As a result of the pathogen capsule shell formation, ascospore Mature, release and ascospores and conidia of the spread, infection and weather conditions are closely linked, so that the varieties in the field of susceptibility (disease panicle disease and disease index) due to the year, sowing date and variety of growth period late Especially in the years when the disease is extremely light, it is difficult to evaluate the wheat varieties with the rate of disease panicles and disease index
