摘　　要： 应用层次分析法(Analytic hierarchy process,AHP)对20个多花黑麦草(Lolium multiflorum L.)品种的产量特性、大田表现、品质特性和抗逆性等4方面15个指标计算的权重和综合评分进行了综合分析.结果表明,按综合评分由高到低可分为5组,第1组仅含二倍体品种LWD8181-2,其产量高,品质好,综合评分最高,综合生产性能最优.第2组包含4个品种,综合性能优良,其中四倍体Jumbo和Common 1鲜草产量和粗蛋白含量较高,特别是Common 1平均粗蛋白含量最高(为质量分数24.8%),但干物质率却低于9%;而二倍体BAR9TAM干物质率最高、干草产量名列第3;01-Lm-1干草产量最高,但粗蛋白含量只有质量分数17.9%.前两组的5个品种可推广种植.第3组Marshall、Archie、Sabroso、Barprisma和第4组Barmultra、LMT 7083、LMT 1107等7个品种,其综合性能一般.第5组中虽然LWD 8115粗蛋白含量高,达质量分数24%,但Barsutra、LM 270、LMT 9034、LWT 8140、Flanker、Common 2、BB-MEX-1等综合性能最差,不适宜在广州地区推广. In order to evaluate the comprehensive productivity of 20 ryegrass varieties planted at Guang- zhou area in winter, the yield, quality, field performance and stress traits including 15 indices of the productivity were analyzed through analytic hierarchy process （AHP）. The comprehensive scores were evaluated, and all varieties were divided into five groups. The results showed that the first group only included diploid LWD8181-2, whose score and productivity were the highest with the best yield and quality. The second group included four varieties whose score and productivity were relatively higher; among the group, the fresh yield and crude protein （CP） content of tetraploid Jumbo and Common 1 were higher, but their dry matter （DM） contents were below 9%, and the average CP content of Common 1 was 24%, which was the highest among all the varieties. The average DM content of diploid BAR9 TAM was the highest, and its DM yield was the third. The DM yield of 01-Lm-1 was the highest, but its average CP was only about 17.9%. The first five varieties mentioned above could be planted widespreadly in Guangzhou in winter. The third group included Marshall, Archie, Sabroso, and Barprisma, and thefourth group included Barmuhra, LMT 7083, and LMT 1107, all their productivities were common. The fifth group included LWD 8115, Barsutra, LM 270, LMT 9034, LWF 8140, Flanker, Common 2, and BB-MEX-1, whose productivities were the worst, although the average CP content of LWD 8115 was 24%.
