Selection of Cyperus esculentus Germplasm Resources Adaptable to Minqin Desert Area
[Objective] It is of strategic significance for Minqin's industrial development to screen out the high-yield and high-oil cyperus ro-tundus 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 dif-ferent 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/hm2. Among the 10 germplasm re-sources, the oleic acid contents of 4 resources were within the range of optimal edible oil fatty acids. Their contents of linoleic acid and linole-nic 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 a-daptable to Minqin desert area.
