摘　　要：以陆地棉品系425系、N13系和968系为试材,研究了枯萎病病级对棉花产量及生物学性状的影响。结果表明,枯萎病对棉花产量影响最大,病级Ⅰ级、Ⅱ级、Ⅲ级和Ⅳ级的病株皮棉产量分别比0级健康棉株减产4.25%、16.4%、29.56%和81.01%,减产显著;不同病级的枯萎病均不会导致黄萎病病情加重。Different rates of Fusarium wilt have different effects on cotton characters.It influenced yield most,then is pant characters.The results are:The percentage of reduced cotton yield are:Ⅰ.4.25 %,Ⅱ.16.4%,Ⅲ.29.6%,Ⅳ.81.0%,The reduced yields are significant.The rate of Fusarium wilt disease had no positive effects on Vericillium wilt.
