摘要
本文通过对10年来黄河流域棉花抗病品比试验资料分析表明,新选育的抗病品种丰产性明显增强,纤维品质逐渐提高,赶上或超过同期的常规品种。虽然棉花抗病育种水平有了提高,抗病性有不同程度下降,但仍说明了棉花品种的产量、品质与抗性之间矛盾并非绝对对立,是可统一的。
It was analysed for cotton variety testing data in Huanghe River basin from 1981 to1990, the results showed that the yield and fibre quality of new disease-resistance varieties of cotton had been improved to catch up with or surpass common varieties; the breeding level of cotton disease-resistance was increased, while disease-resistance decreased to some extent, but it would not be bsolutely contradictory for yield, quality and disease-resistance of cot- ton, it could be unified.
