1983年关中、陕南是小麦条锈病轻度流行年份。即上年秋苗虽罹病重,但菌源越冬率不高,春季菌量积累慢,发病迟而轻,产量损失不显著。结合秋、春季病情调查,本年度在陕、甘、川、宁4省(区)32县(市)的大田和全国统一锈圃中,共采集了700多份菌样,进行了生理小种鉴定。有结果的共计649份(包括秋季菌样164份,春季菌样485份)。 Guanzhong in 1983, southern Shaanxi is a mild epidemic of wheat stripe rust year. In autumn autumn last year, although the disease was heavy, but the source of overwintering is not high, slow accumulation of bacteria in spring, late onset of light, yield loss is not significant. Combined with autumn and spring disease survey, more than 700 strains of bacteria were collected from paddy fields and uniformed uniforms in 32 counties (cities) of Shaanxi, Gansu, Sichuan and Ningxia provinces in this year, and physiological races were identified . The results of a total of 649 (including 164 samples of autumn, spring 485).
