In order to cultivate high-yielding and high-quality varieties of Camellia oleifera and increase the yield and economic benefits of the local Hainan Camellia oleifera, this study conducted a detailed investigation on the excellent Camellia oleifera trees in different producing areas in Hainan Province, and carefully selected 30 excellent Camellia oleifera trees for systematic analysis. The economic traits, biological characteristics, fatty acid composition and content, correlation of main fatty acids and the quality of camellia oil were analyzed in detail. The results show that the indicators of fruit economic traits are all significantly different (P<0.01); the excellent quality of Camellia oleifera with excellent main biological characteristics have better quality of camellia oil, and vice versa; the fatty acid composition and content also show for different differences, the content of linoleic acid varies greatly, while the content of oleic acid is relatively stable; the correlation between oleic acid and linoleic acid and palmitic acid is extremely significantly negatively correlating, while it is significantly positive for stearic acid related.; Hainan Camellia oleifera excellent tree the biological characteristics of oleoresin are good, but there are also differences to a certain degree, which affects its quality differences; the impact of different producing areas in Hainan on the quality of camellia seed oil may also be related to factors such as latitude, precipitation, sunshine, and temperature, which in turn caused there are certain differences in the quality of tea oil from different producing areas in Hainan. With the continuous in-depth study of its fruit traits and biological characteristics, it provides a reference for future Hainan Camellia breeding work.
