应用相互嫁接技术研究棉花对黄萎病的抗性
Use of Reciprocal Grafting to Study Verticillium Wilt Resistance of Cotton
摘要
Abstract
In an attempt to better understand the resistance mechanism of cotton to Verticillium wilt,cotton lines with different resistance levels to Verticillium wilt were selected,and reciprocal grafting were made between resistant and susceptible genotypes. The grafted combinations were planted in the naturally infected cotton field,and the data of cotton Verticillium wilt were investigated. The results indicated that the resistance level was not significantly different between self-root cotton and their self-grafted cotton. The resistance of resistant/susceptible and susceptible/ resistant grafted combinations was higher than that of susceptible/susceptible combination, but lower than that of resistant/resistant combination. Resistant cotton genotypes either as stock or scion can inhibit Verticillium wilt,which indicates that the whole plant of resistant cotton can resist to Verticillium wilt.关键词
