国内外实践证明,种植抗病品种是防治棉花枯萎病和黄萎病的有效途径,种质资源鉴定,筛选抗源是培育抗病品种的重要前提。 我们于1972-1978年在新乡王屯重病田对204份材料进行成株期抗枯萎病鉴定(自然病圃法);1986—1988年在北京本所温室对1007份材料进行苗期抗枯萎病鉴定(纸钵菌土法);1983-1988年在北京本所黄萎病圃对2072份材料进行成株期抗黄萎病鉴定(人工病圃法):1984-1985年在北京本所温室对394份陆地棉进行苗期抗黄萎病鉴定(纸钵撕底蘸根法)。通过对3677份(次)材料的鉴定,初步明确了我国棉花种质资源对枯、
Domestic and foreign practice has proved that planting resistant varieties is an effective way to prevent and control cotton wilt and Verticillium wilt. Germplasm resources identification and screening of anti-source are important prerequisites for cultivating resistant varieties. In 1972-1978, we identified 204 adult plants as Fusarium wilt resistance (natural disease nursery) in Wangtung County, Xinxiang from 1972-1988. In 1986-1988, 1007 materials were subjected to Fusarium wilt Identification (Worm soil method); 1983-1988 in Beijing Institute of Verticillium wilt of 2072 materials for identification of anti-verticillium wilt (artificial disease nursery): 1984-1985 in the Beijing Greenhouse Resistance to Verticillium wilt was evaluated at seedling stage in 394 upland cottons. Through the identification of 3677 copies of materials, the preliminary identification of China’s cotton germplasm resources on dry,
