黄河区试、长江抗病区试、麦套棉区试和夏棉区试三轮试验的60个品种的抗病性鉴定结果表明,参试品种的抗枯萎病性水平较高,而抗黄萎病性和兼抗性水平较低。90年代以来参试品种的抗病性发展趋势为抗枯萎病性在达到较高水平后趋于稳定;抗黄萎病性和兼抗性为上升趋势。不同熟性品种的抗病性有明显差异,表现为早熟棉品种的抗枯、黄萎病性和兼抗性均优于中熟棉品种。来自黄河流域棉区参试品种的抗病性明显优于来自长江流域棉区的参试品种。
The results of disease resistance identification of 60 cultivars in the Yellow River Zone, the Yangtze River Disease Resistance Zone, the Wheat Cotton Zone and the NAP Zone Test showed that the resistance of the tested varieties to Fusarium Wilt was high, Low wilt and concurrent resistance. The development trend of disease resistance of the tested cultivars since the 1990s was that the resistance to fusarium wilt stabilized after reaching the higher level; the resistance to Verticillium wilt and resistance also increased. The disease resistance of different maturity cultivars were significantly different, which showed that the resistance to dry, verticillium wilt and resistance of precocious cotton varieties were better than those of medium mature cotton varieties. The resistance of cotton cultivars from the Yellow River Basin was significantly better than that of the cotton cultivars from the Yangtze River Valley.
