棉花对枯、黄萎病的抗性研究
STUDIES ON COTTON RESISTANCE TO Fusarium AND Verticillium WILT
【摘要】 以一组抗病和丰产品种(系)为材料对棉花的抗枯、黄萎病性进行了研究,结果表明:抗病品种(系)对7号枯萎菌生理小种抗性较好,一般能够达到病指小于10的育种目标。各供试材料对8号枯萎菌生理小种和7号、8号混合枯萎菌生理小种抗性较差,没有出现高抗材料。全部供试材料都不抗黄萎病,病情指数都在50以上。相关分析表明,棉花对不同类型的枯萎菌生理小种的抗性存在高度正相关,但抗枯萎病性和抗黄萎病性二者相关性较低。
【Abstract】 Several cotton cultivars and lines were used to investigate their resistance to Fusarium and Verticillium wilt. Some of these materials were highly resistant to race 7 of Fusarium oxysporum f. sp. vasinfectum, but all of them were susceptible to race 8, mixed races of 7 and 8, and Verticillium wilt. There was a highly positive correlation between their resistance to different races of Fusarium wilt, while a loose one between their resistance to Fusarium and Verticillium wilt.
