摘　　要：[目的]筛选出适宜在民勤荒漠区推广种植的高产高油油莎豆,对民勤产业发展具有重要的战略意义。[方法]引入10个不同种质资源油莎豆,观测其出苗率,测量产量和油脂含量,同时运用SPSS软件对比分析不同种源地油莎豆种质资源的产量、油酸含量,以及人体不能合成而必须从膳食中补充的亚油酸和亚麻酸含量。[结果]不同种源地油莎豆种质资源之间产量有差异;不同种源地油莎豆种质资源之间油酸、亚油酸含量差异显著;引入的10个不同种源地油莎豆种质资源中,出苗率均超过90%,产量均超过6000.0 kg/hm^(2),其中有4个油莎豆种质资源的油酸含量位于最佳食用油脂肪酸组成区间,其亚油酸和亚麻酸含量由高到低排序为河南油莎豆、西班牙油莎豆、中科院油莎豆6号、武汉1号。[结论]适宜在民勤荒漠区推广种植的高产高油油莎豆种质资源依次为河南油莎豆、西班牙油莎豆、中科院油莎豆6号和武汉1号。[Objective]It is of strategic significance for Minqin’s industrial development to screen out the high-yield and high-oil cyperus rotundus suitable for planting in Minqin’s desert areas.[Method]Ten different germplasm resources of Cyperus esculentus were introduced,their emergence rate,yield and oil content were observed,and the yield and oleic acid content of C.esculentus germplasm resources from different provenances were analyzed by SPSS Software,as well as the linoleic acid and linolenic acid contents,which could not be synthesized by the human body but must be supplemented from the diet.[Result]The yields of C.esculentus from different provenances were different.Their contents of oleic acid and linoleic acid were significantly different.For the 10 C.esculentus germplasm resources introduced from different provenances,their germination rates were all beyond 90%and the yields were all more than 6000.0 kg/hm^(2).Among the 10 germplasm resources,the oleic acid contents of 4 resources were within the range of optimal edible oil fatty acids.Their contents of linoleic acid and linolenic acid were in the order of Henan species>Spain species>Chinese Academy of Sciences No.6>Wuhan No.1.[Conclusion]Therefore,Henan species,Spain species,Chinese Academy of Sciences No.6 and Wuhan No.1 were the optimal C.esculentus germplasm resources adaptable to Minqin desert area.
