凉山州8株野生油茶经济性状及脂肪酸组成分析OA

Abstrct:[Objective]This study was conducted to fully explore the exotic Camellia oleifera Abel resources and accelerate the breeding process of Camellia oleifera Abel in Liangshan Yi Au-tonomous Prefecture.[Method]The fruiting characters,economic characters and fatty acid compo-sition were determined for 8 collections of wild Camellia oleifera Abel in Liangshan Yi Autonomous Prefecture.[Result]The results showed that the fresh fruit weight per fruit in 8 collections of Ca-mellia oleifera Abel ranged from 8.29 g～15.30 g,the fruit shape was ovoid or globular,and the peri-carp was relatively thin.The fresh seed rate ranged from 38.96%～45.25%,the dry seed rate ranged from 26.57%～29.59%,and the dry seed kernel rate ranged from 63.15%～76.49%,the kernel oil content ranged from 48.87%～55.63%,and the oil content of fresh fruit ranged from 9.66%to 11.35%.Fatty acid was mainly composed of palmitic acid,palmitoleic acid,heptadecanoic acid,stea-ric acid,oleic acid,linoleic acid and cis-11-eicosenoic acid,and the content of unsaturated fatty acid was more than 80%.[Conclusion]The oil content of Camellia oleifera Abel in Liangshan Yi Au-tonomous Prefecture was outstanding,which could provide elite genetic resources for breeding of va-rieties with high oil content.DC10,DC18,DC19,DC21,YL12,HL20 and HL26 had more promi-nent overall characters and could be regard as candidate germplasm for breeding of elite varieties.
