摘要
应用棉花黄萎病菌 (Verticilliumdahliae)毒素在棉花苗期对 32份棉花材料进行了抗黄萎病性初筛和田间病圃鉴定 ,未发现高抗材料 ,抗病类型仅占全部试材 9 4 % ,耐病类型占 5 0 0 %。抗性表现较好的 4个抗黄萎病种质材料为R1、R2 、R3 和R4。
The resistance of 32 cotton cultivars to Verticillium wilt disease were tested. Used toxin-method, the preliminary screening showed that 9.4% of the cultivars were resistant and 50.0% were tolerant. The futher test in the diseased field revealed that 4 cultivars of inclusion R 1, R 2, R 3 and R 4, showed high resistance to Verticillium wilt.
