In order to select improved varieties, a study on the fine individual selection was carried out in Pengshui County, Chongqing Province. For 14 fine individuals with high and stable yield preliminarily screened, eight factors(fruit height, fruit diameter, pericarp thickness, fresh fruit weight, fresh seed weight, dry seed weight, dry seed yield and fresh seed yield) related to yield were selected to perform principal component analysis, and based on comprehensive scores and oil contents, five fine individuals(Longshe Town 7, 8, 12, 17 and Shaoqing Street 2) of Camellia pitardii were determined. These fine individuals have a better performance.
