摘要
大豆灰斑病是中国北方春大豆品种区域试验必须鉴定的重要病害之一,为明确东北地区大豆种质资源抗灰斑病差异,积累优异抗源材料,本研究采用叶面喷雾法,以东北地区大豆种质资源为供试材料对大豆灰斑病优势和强毒性小种进行混合接种。结果表明,306份鉴定材料中高抗26份,占供试材料的8.5%;抗病67份,中抗47份,分别占供试材料的21.9%和15.4%;不同地区大豆种质对灰斑病的抗性存在差异,辽宁省表现为抗病的种质所占本省比例要高于吉林省和黑龙江省,育成品种在不同抗性级别的品种所占比例均高于地方品种。高抗种质的农艺性状类型较为丰富,紫花或圆叶居多,百粒重和生育期分布较广。
Soybean frogeye leaf spot is one of the most important diseases that must be identified in north regional trials. In order to clarify the difference of the resistance and accumulate excellent resistance source material, 306 soybean germplasm resources mainly from northeast China were used to screen and evaluate the resistance with dominant and highly toxic physiological races by foliar spraying in this study. The result showed that 26 materials were highly resistant, accounting for 8.5% of the total of materials, 67 were resistant and 47materials were medium resistant, accounting for 21.9% and 15.4% respectively. The resistance of soybean germplasm to frogeye leaf spot disease was different in different regions, Liaoning Province has a higher proportion of disease-resistant materials than Jilin and Heilongjiang, the resistance level of bred varieties were higher than local varieties. The agronomic character types of high resistance germplasm were abundant, mostly purple flowers or round leaves, and the 100-seed weight and growth period of resistant cultivars were widely distributed.
