| 中文摘要: |
| 以20个苜蓿(Medicago sativa L.)品种为材料，研究其对苜蓿炭疽病(Colletotrichum truncatum)的抗性。通过对不同苜蓿品种抗苜蓿炭疽病的室内鉴定，以苜蓿的病叶量作为测定指标并对数据进行聚类分析。结果表明，不同品种抗苜蓿炭疽病能力的强弱不同，通过聚类分析将供试品种划分为4个类群，以ProINTA Patricia和Victoria SPI对苜蓿炭疽病的抗性最好，Defi德福、Lobo路宝、Salado萨兰多、新疆大叶苜蓿和Travois的抗病性最差，其他品种呈中等抗性。 |
| 英文摘要: |
| In this study, 20 cultivars of alfalfa, Medicago sativa L., were tested for their resistance to Colletotrichum truncatum. Based on the number of ailing leaves, the resistance of alfalfa cultivars to C.truncatum were tested, and cluster analysis was made.The results showed that the 20 cultivars could be clustered into 4 groups based on their resistances to C.truncatum, among which ProINTA Patricia and Victoria SPI were the best, but Defi, Lobo, Salado, Xinjiang large-leaf and Travois were the weakest, while the other 13 cultivars had medium resistance to C.truncatum. |
