| 中文摘要: |
| 橡胶树抗性种质的鉴定与利用是控制橡胶树炭疽病的一项重要措施。采用室内离体橡胶叶接种法、田间种质圃人工接种和自然发病条件下定期田间病害调查方法， 2011-2012年在海南省儋州开展46份重要橡胶树种质对胶孢炭疽菌病抗性鉴定和评价。把抗炭疽病程度划分为高度抗病(HR)、抗病(R)、中度感病(MS)、感病(S)和高度感病(HS)共5个级别，根据抗性评价结果分析得出：高度抗病(HR)类型的0份；抗病(R)类型8份, 占17.39%； 中度感病(MS)类型19份，占41.30%；感病(S)类型16份，占34.78%；高度感病(HS)类型3 份，占6.52%。筛选出的抗病品种，是今后可利用的抗性种质资源。本研究结果为炭疽病抗性种质资源的利用、培育及病害管理提供参考数据。 |

| Identification of resistant clones is a major strategy in the management of Colletotrichum leaf disease (CLD) of rubber. Three methods for identifying resistance/susceptibility to CLD of 46 rubber clones were examined in this study at Danzhou of Hainan province from 2011 to 2012. The resistance was divided into 5 grades: highly resistant (HR), resistant (R), moderately susceptible (MS), susceptible (S), and highly susceptible (HS). The results showed that among the 46 rubber clones, there were 0 highly resistant (HR), 8 resistant (R), 19 moderately susceptible (MS), 16 susceptible (S), and 3 highly susceptible (HS), accounting for 0%, 17.39%, 41.30%, 34.78% and 6.52%, respectively. Copper brown leaves were the most susceptible to the pathogen. Annual occurrence of disease could be divided into two periods: the frequent period and infrequently occurring period. Environmental factors against the rubber tree would aggravate the disease. The results of our research provided important information for disease-resistant breeding, clone utilization as well as the management of CLD. |
