In order to promote the production of olive fruit from different varieties in Shiyan, in November 2022, the fruits of olive Yuntai, Picholine, Ezhi 8, Arbosana, Dou guo and QIji in Shiyan Area were collected, and the relevant agronomic traits, total acid and soluble solid percentage contents were detected, and correlation analysis and principal component analysis were conducted. The results showed that there were different variability in fruit maturity and agronomic traits of different olive varieties in November, the fruit longitudinal and transverse diameter, single fruit weight, dry matter pereentage contents of olive were the largest, soluble solids percentage of 8.30%-9.88% and total acid percentage of 1.06%-1.92%, which were ready for harvested, but the fruits of Arbosana, Douguo and Qiji were not suitable for harvesting. The results of principal component analysis of fruit agronomic traits of 6 olive varieties were consistent. In addition, the correlation analysis of agronomic traits of the fruits of olive Yuntai showed that, there was a significant negative correlation between the fruit shape index and the longitudinal and transverse diameter, and the flesh weight was positively correlated with the single fruit weight and contrary to the transverse diameter in November.
