河南省小麦品种对赤霉病的抗性分析

目的]研究河南省新育成小麦品种(系)对赤霉病的抗性。方法]通过对参加2014—2015年河南省水地小麦区试53个品种(系)的分析,研究河南省新育成小麦品种(系)对赤霉病的抗性及其与丰产性的关系。结果]92.5%以上品种(系)高感赤霉病,在参试品种(系)中,濮麦8062中抗赤霉病,产量达8 310.0 kg/hm~2。结论]该研究为提高河南小麦对赤霉病的抗性和小麦产量提供理论依据。

Resistance Analysis of Henan Wheat Varieties Against Gibberellic Disease

Objective] To study resistance of Henan wheat varieties against gibberellic disease.Method] Through analysis on 53 varieties of wheat during 2014-2015 Henan regional experiments, the relationship between the resistance of the newly-breding wheat varieties against the gibberellic disease and the yield was investigated.Result] More than 92.5% of the wheat varieties were of high sensitivity to the gibberellic disease and that wheat 8062 was moderately resistant against gibberellic disease with the yield up to 8 310.0 kg/hm2.Conclusion] The study provides the theory basis for improving resistance against wheat gibberellic disease and wheat yield.
