赤霉病是我国黄淮以南小麦主要病害,其引起产量损失绝不次于锈病。我省小麦生长后期,正处于多雨高湿季节。因此纵有高效农药,防效也不理想。近年,我省部分地区改种鄂麦6号等抗(耐)病品种,病害比种友谊麦时大大减轻。可见推广以抗病品种为中心的综合防治,是克服赤霉病危害最经济最有效的措施。但抗病品种的育成,首先必须依赖抗病遗传资源的可靠性和使用的准确性,才能取得预期的效果。为了给抗病育种寻找抗源和给大田品种布局提供依据,我所于1974—1981年期间,先后对国内外引进和省内现保存的品种(系)进行了抗赤霉病鉴定,现将结果整理报道如次。
Fusarium head blight is a major disease of wheat in the south of Huanghuai in China, which causes the yield loss not to be inferior to that of rust. The late wheat growth in our province, is in a rainy high humidity season. Therefore, even if efficient pesticides, anti-efficiency is not satisfactory. In recent years, in some areas of our province, some varieties of resistant and resistant varieties such as Emai 6 have been rebuilt and the diseases have been greatly alleviated when compared with the friendship wheat. It can be seen that the promotion of comprehensive prevention and control centering on resistant varieties is the most economical and effective measure to overcome the hazards of scab. However, the breeding of disease-resistant varieties must first rely on the reliability and accuracy of the genetic resources for disease-resistant disease in order to achieve the desired results. In order to find a source of resistance to disease-resistant breeding and to provide a basis for the distribution of varieties in the field, during the period 1974-1981, we identified the varieties (lines) that have been introduced both in China and abroad, Results finishing reported as follows.
