长江中下游小麦生长期间的基本气候特征是:春季降水量大;早春气温回升较慢,但嗣后有一个较大的跃迁.加之滨湖低地麦田多,地下水位高,为病害流行创造了有利条件,在菌量充足、品种抗性差的情况下,易于造成严重流行.因此,近年来育种和生产部门对品种的抗病性越来越重视,抗病性成为生产品种的基本要求之一.而抗病育种的先
The basic climatic characteristics of the wheat growing in the middle and lower reaches of the Yangtze River are as follows: large amount of precipitation in spring; early spring temperature recovery slowly, but later a larger transition, combined with abundant wheat fields and high groundwater table in lowland lake, creating favorable conditions for disease epidemic , In a sufficient quantity of bacteria, the case of poor varieties of resistance, easy to cause serious epidemic.Therefore, in recent years breeding and production departments of varieties of disease resistance has become increasingly important, disease resistance has become one of the basic requirements of the production of varieties. Disease-resistant breeding first
