摘　　要：通过对1107份甘薯种质资源抗黑斑病鉴定,筛选出高抗品种8份,占鉴定品种总数的0.7%;抗病品种128份,占11.6%。并进一步对这些抗性资源的兼抗病性、抗逆性、产量及品质进行分析研究,从中筛选出了兼抗两种或两种以上病害的优异种质资源若干份,以期为育种和生产提供依据。Resistance to black rot of totally 1107 sweet potato germplasm were evaluated. 8 varieties(0.7% ) were evaluated as germplasm with high resistance and 128 varieties(11 .6% ) were evaluated as germplasm with resistance. Comprehensive evaluation such as the resistance to other diseases,the yields and the quality,were also done for the accessions with resistance to black rot disease.
