[目的]筛选出适合西双版纳州勐海县种植的大麻品种(系),为西双版纳州云麻产业健康、持续和稳定发展奠定坚实的基础.[方法]以云麻5号、云晚6号、云晚9号、云晚10号、皖大麻1号、汾阳1号、PB-1、PB-2、PB-3、PB -4、PB-5、云麻1号(CK)12个品种为试材,观测各品种(系)的物候期,在收获期测定各品种(系)的经济性状、纤维产量、纤维的化学成分等项目.[结果]工艺成熟期最晚的品种为PB-3,最早的品种为汾阳1号,两者相差70 d；PB-3的纤维产量最高,为2694.0 kg/ha,但纤维品质稍差；云晚6号和云麻5号的综合性状较好；云麻1号(CK)、云晚10号、云晚9号、和PB-4纤维产量稍低,分别为2221.5、2110.5、1944.0和1914.0 kg/ha;其他品种(系)的产量均较低.[结论]云晚6号、云麻5号和PB-3适宜在西双版纳州勐海县推广种植,而云麻1号、云晚10号、云晚9号和PB -4的纤维产量较高,为次适宜推广种植品种,其他品种(系)纤维产量较低,不宜在西双版纳州勐海县推广种植.%[Objective]The present experiment was conducted to select suitable cultivar for planting in Menghai region of Xishuangbanna in order to sustainably develop hemp industry in this area. [Method]Phenophases, agronomic traits, fiber production and fiber chemical composition of hemp varieties, viz., Yunma 5, Yunwan 6, Yunwan 9, Yunwan 10, Wandama 1, Fenyangl, PB-1, PB-2, PB-3, PB-4, PB-5 and Yunma 1 (CK) were investigated. [ Result ]The longest technical maturity period of PB-3 was found 70 days higher than Fenyang 1. PB-3 had the highest fiber yield (2694.0 kg/ha) but a little poor fiber quality. Comprehensive traits of Yunwan 6 and Yunma 5 were relatively fine. Yunma 1 (CK), Yunwan 10, Yunwan 9 and PB-4 had relatively lower fiber yield which was 2221.5, 2110.5, 1944.0 and 1914.0 kg/ha, respectively. The yield of other varieties was low. [ Conclusion ] Yunwan 6, Yunma 5 and PB-3 were found suitable for planting in Menghai County, followed by Yunwan 10, Yunwan 9, and PB-4 being good for higher fiber yield. The other varieties with lower fiber yield should not be planted in this region.
