摘　　要：１９９７～１９９８年，在以中等致病力菌系为主的田间病圃中，对２１７价低酚棉品种资源的抗黄萎病性进行了鉴定。结果表明，抗病类型品种仅占总数的７．４％，且无高抗类型品种；耐病品种占３８．９％；感病品种占有较大比例（５３．７％）。以河北省培育的品种抗黄萎病性较好，抗病品种比例占１６．７％；中国农业科学院棉花研究所培育的抗病品种比例为５．４％，其它省份平均为６．２％；从国外引进的低酚棉资源抗病类型仅为３．６％。河北省及中国农业科学院棉花研究所培育的品种耐病类型比例也较高。抗病性突出的材料有省无３０３、７５１８９３－１、中无１４－６、豫无６２０和邯无８９５１等。From 1997 to 1998, the identification of resistance to Verticillium wilt of 217 glandlesscottons in field nursery infected by intermediately virulent strains was conducted. The results indicated that resistant, tolerant and susceptible cotton varieties accounted for 7. 4 %, 38. 9% and53.7 % of the total, respectively, and no highly resistant cottons was found. The disease resistance of varieties from Hebei province was better, with a ratio of 16. 7% for the resistant materials. Ratios of resistant materials in varieties developed by Cotton Reseach institute, CAAS, otherprovinces and foreign countries were 5. 4 %, 6. 2 % and 3. 6 % , respectively. Moreover, among thevarieties bred by Hebei province and Cotton Reseach institute, CAAS w as the higher ratio of tolerant materials. The best resistant varieties selected were Shengwu303, 751893 - 1, Zhongwu14 -6, Yuwu620 and Hanwu8951.
