中文摘要:
      在广东烟叶主产区,采用广东烟区分离的中等致病力青枯菌灌根接种方法,随机区组设计,3 次重复,对 65 份烟草资源进行青枯病抗性鉴定。结果表明;从参试材料中,筛选出高抗青枯病的资源7 份,分别为OX2028、岩烟 97、CO176、C151、大叶密合、NC95、K730,病情指数在10.83~22.78 之间,其中大叶密合为广东地方晒烟品种;中抗青 枯病的资源10 份,分别为RG-8、G28、K399、CO139 、K326(系选)、中烟14、K346、RG-22、RG11、R-158,其病情指数在 30.97~49.44 之间。
英文摘要:
      Sixty -five tobacco germplasm were identified and classified on their resistance to bacterial wilt in Guangdong province. The results showed that 7 varieties (OX2028, Yanyan 97, CO176, C151, Dayemihe, NC95, K730) were proved to have high resistance, their disease indexes were 10.83-22.78. Dayemihe was a domestic variety from Guangdong province. 10 varieties (RG8, G28, K399, CO139, K326, Zhongyan 14, K346, RG-22, RG11, R158) were proved to have medium resistance, their disease indexes were 30.97-49.44.
