高粱丝黑穗病[Sphaeelotneca reiliana(kühn)clinton]近年来在省内外各地为害严重,一般发病率在5.0%左右,个别严重地块高达15～20%,是高粱生产中急待解决的课题。据过去研究,高粱丝黑穗病菌的厚垣孢子在土壤里能存活二年以上、属土壤传染的病害,只靠药剂拌种,收效不大。总结国内外经验,选育抗病品种是防治丝黑穗病的根本措施。鉴于我国土地辽阔,高粱种质资源丰富,类型众多,可能蕴藏抗源和抗病品种。为此,将全国23个省、自治区的中国高粱品种1016
In recent years, Sphaeelotneca reiliana (kühn) clinton has been seriously devastated in both inside and outside the province, with a prevalence of about 5.0% and individual parcels of up to 15-20%. It is an urgent issue in sorghum production. According to the past study, sorghum Smut spore chlamydospore in the soil can survive more than two years, is a soil infection disease, relying on pharmaceutical seed dressing, with little success. Summarizing the experience both at home and abroad, breeding of resistant varieties is the fundamental measure to prevent head smut. In view of the vast land in our country, sorghum is rich in germplasm resources and has many types, which may contain resistant and disease resistant varieties. To this end, China will be 23 provinces, autonomous regions of China sorghum varieties 1016
