| 中文摘要: |
| 由胶孢炭疽菌（Colletotrichum gloeosporioides）侵染引起的柑橘炭疽病是柑橘的主要真菌病害。为研究不同柑橘品种对炭疽病的抗性，本试验采用室内人工接种法，根据病情指数、平均直径、系统聚类分析3种不同抗性评价方法来探讨52个柑橘品种对胶孢炭疽菌的抗性。结果表明：参试的种质资源共分为高抗、抗病、中抗、感病四类，未发现免疫和高感种质，胡柚、晚棱脐橙等8个品种为高抗品种。本文讨论了不同柑橘品种间的抗性差异，为下一步的抗柑橘炭疽病育种提供了理论依据。 |
| 英文摘要: |
| Anthracnose caused by Colletotrichum gloeosporioides is an important disease in citrus production. To evaluate the disease resistance to anthracnose, fifty-two citrus varieties were analyzed with the artificial inoculation method by disease index、average diameter and system cluster analysis method. These citrus varieties could be divided into the highly resistance、resistance、medium resistance and susceptible varieties without immune and highly susceptible to anthracnose. Eight varieties are highly resistance, such as Citrus grandis Huyou 、Citrus sinensis Wanlengqicheng . This study definited the resistance difference in citrus varieties so as to provide a theoretical basis for citrus anthracnose resistance breeding programs in the future. |
