摘要
槟榔黄叶病毒病是由槟榔长线型病毒1(Areca palm velarivirus 1,APV1)引起的一种致死性病害,目前尚无有效的防控措施。培育抗(耐)病品种是解决槟榔病理黄化的关键途径,而收集优异资源材料则是育种工作的重要物质来源。本研究以海南槟榔病理黄化三大重灾区(屯昌、琼海、万宁)为调查区域,系统开展资源收集、表型观测、病原检测及持续跟踪等研究。研究结果表明,在收集的200份槟榔资源材料中,100份抗(耐)病资源中有84份未检测出APV1,而100份感病资源中有92份检测出APV1,这一发现证实APV1与植株病理黄化表型之间存在密切关联,同时表明所筛选的抗(耐)病资源具有代表性。通过持续跟踪观察与关联分析,发现槟榔树龄与抗(耐)病之间呈显著负相关。本研究成功筛选出一批具有抗(耐)病特性的槟榔种质资源,为后续抗病品种的培育奠定重要的物质基础。
Areca palm leaf yellowing virus disease,caused by Areca palm velarivirus 1(APV1),is a fatal disease for which no effective control measures currently exist.Breeding resistant or tolerant varieties is the key approach to addressing this issue,while the collection of superior germplasm resources is an essential foundation for breeding efforts.This study focused on three major affected areas in Hainan Province(Tunchang,Qionghai,and Wanning)and systematically conducted research activities including germplasm collection,phenotypic observation,pathogen detection,and long-term monitoring.The results revealed that among the 200 areca palm germplasm materials collected,84 out of 100 resistant/susceptible materials did not show the presence of APV1,while 92 out of 100 susceptible materials tested positive for APV1.This finding confirmed a close association between APV1 infection and plant yellowing symptoms,and demonstrated that the screened resistant/tolerant materials are representative.Through continuous observation and correlation analysis,a significant negative correlation was found between tree age and resistance/tolerance to the disease.This study successfully identified a group of betel palm germplasm resources with resistance/tolerance traits,laying a crucial foundation for the development of disease-resistant varieties in future breeding programs.
