摘　　要：用筛选出的强致病性花叶病病毒分离物(SrMV-HH1)对国家甘蔗种质资源圃保存的14份甘蔗属资源材料及11份杂交后代材料,采用甘蔗生长期切茎接种法进行抗花叶病鉴定与评价。结果表明,1级免疫材料13份(52.0%),3级中抗材料3份(12.0%),4级感病材料6份(24.0%),5级高感材料3份(12.0%)。The resistance of 25 sugarcane gemplasm resources which were chosen from the collections of NNSGR （ National Nursery of Sugarcane Germplasm Resources, Kaiyuan, China） to SrMV-HH1 was evaluated by spraying stem-cutting inoculation during growth period. The result showed that of the 25 samples, 13 were immunity （52.0%）, 3 were moderately resistant （ 12.0% ）, 6 displayed susceptibility （24. 0% ） and 3 displayed high susceptibility （12. 0% ）.
