为了明确黑龙江省北部地区大豆种质资源对大豆疫霉根腐病的抗耐情况，采用下胚轴创伤接种法，对适宜该地区种植的113 份大豆育成品种或育种材料的大豆疫霉根腐病抗性开展鉴定。结果显示:共鉴定出7 份抗病种质，占鉴定总数的6。19%;5 份中间类型种质，占鉴定总数的 4。42%。其中，从第三积温带种质中鉴定出 1 份抗病种质，中间类型种质1 份;从第四积温带种质中鉴定出抗性种质3 份，中间类型种质 2 份;从第五积温带种质中鉴定出抗性种质1 份，中间类型种质2 份;从第六积温带种质中鉴定出抗性种质 2 份，未见中间类型种质。结果表明在不同积温带参试材料中均存在抗性种质。该研究结果为黑龙江省北部地区培育和利用抗疫霉根腐病大豆种质提供了参考。
Resistance Evaluation of Soybean Germplasm Resources to Phytophthora Root Rot in Northern Heilongjiang
In order to explore soybean germplasm resources resistant to Phytophthora root rot in northern region of Heilongjiang province,113 soybean varieties and breeding materials were identified by wound inoculation on soybean hypocotyl.The result showed that seven soybean resistant germplasms were screened,accounting for 6.19%of the total identified soybean,and five medium resistance germplasms were obtained,accounting for 4.42%of the total identified soybean.Among them,one resistant germplasms and one medium resistant germplasms were identified from the third accumulated temperature zone varieties.Three resistant resources and two medium resistant germplasms were obtained from the fourth accumulated temperature zone varieties.One resistant germplasm and two medium resistant germplasms were screened from the fifth accumulated temperature zone varieties.Two resistant resources were identified from the sixth accumulated temperature zone varieties,but no medium resistant germplasms were found.Therefore,resistant germplasms were already obtained from different accumulated temperature zones.The results provide a reference for the breeding and utilization of soybean germplasm with resistance to Phytophthora root rot in northern Heilongjiang.
