摘　　要：收集国内外黄瓜嫁接砧木20份,采用自然鉴定和人工接种鉴定,对其抗南方根结线虫能力进行鉴定评价。结果表明,无论自然鉴定和人工接种鉴定,所有供试砧木均表现为感病,通过聚类分析进一步划分为低感、中感和高感3种类型;按照隶属函数值大小,云南黑籽南瓜、黒タネ南瓜、エイブル抗南方根结线虫能力较强,ジャスト、青研1号和雪砧金刚F1较弱;人工接种鉴定和隶属函数值运用相结合,鉴定结果更准确可靠。Twenty cucumber rootstocks collected from home and abroad were analyzed to evaluate their capacity in resistance to Meloidogyne incognita using natural identification and artificial inoculation identification. The result showed that all of the rootstocks were susceptible and could be divided into three classes： low sensitive, middle sensitive, and highly sensitive through clustering analysis; according to the value of membership function methods, ＇ Figleaf gourd＇, ＇ Kurotane＇ and ＇ Eibulu＇ had a stronger resistance capacity, while ＇Shiasuto＇, ＇Qingyan No.l＇, and ＇xuezhenjingang Fl＇with a weaker one. Association of artificial inoculation identification with membership function methods could give more accurate result.
