近年来,随着大豆品种和气候的变化,灰斑病在黑龙江大豆产区广泛发生,并呈逐年加重的趋势。为了筛选出可在生产或育种中利用的抗病材料,本试验在人工接种条件下,对1073份大豆材料进行抗灰斑病鉴定和评价,结果表明,高抗材料33份、抗病材料291份、中抗材料332份、感病材料381份、高感材料36份,分别占供试材料的3.1%、27.1%、30.9%、35.5%、3.4%。对1、6、7号出现频率较高的优势生理小种鉴定结果是高抗和抗病材料分别是161份、68份、95份,分别占供试材料的15%、6.3%、8.9%。在现行大豆种质资源中,具有比较丰富的抗病资源。
During last decades, C. sojae become more severe in the Heilongjiang soybean production region due to the change of the soybean cultivars and clmiate. To obtain some resistant to C. sojae in soybean production and breeding, we evaluate and appraise the resistance of C. sojae from 1073 portions of Soybean resource under artificial infection condition. The results showed that there were 33 portions of high resisted resource, 291 portions of resisting disease, 332 portions of moderate resistance、381 portions of affecting disease, and 36 portions of highly affecting resource, which respectively occupied 3.1%、27.1%、30.9%、35.5%、3.4%. We also found much higher frequent advantage of physiological seeds from Number 1, 6 and 7 were 161 portions, 68 portions, 95 portions, which occupied 15%、6.3%、8.9% respectively. All these results showed that there are plenty of anti-disease sources in recent soybean germplasm resources.
