Abstract: In order to screen out the varieties of clonal Changlin Camellia oleifera suitable for planting in the mountainous areas of southwestern Zhejiang Province, seven new Camellia oleifera varieties such as Changlin No.3 and No.4 were used as the studied materials, and a complete randomized block design comparison experiment was used. The tree height, crown width and yield were studied after seven years of planting. The results showed that the average height of No.4, No.23, No.40 and No.166 was above 210 cm, and the average crown width of No.4, No.23, No.40, No.53 and No.166 reached 215 cm. In 2018, the average yield per plant of Changlin NO.3, NO.4, NO.23, NO.40, NO.53 and NO.55 reached above 4 kg, which was 81.61%~291.03% higher than the control. In 2019, the average yield per plants of Changlin NO.3 and NO.4,No.23, No.40, No.53 and No.55 reached above 3 kg, which increased by 30.34%~194.87% compared with the control. The dry seed yield of the seven varieties of Changlin species were 2.06%~18.87% higher than the common species. As for dry kernel yield of No.23, No.55 and No.166 was 1.73%~5.63% higher than that of common species, and the oil content of Changlin No.23 was 52.95%, which was 9.65% higher than that of the common species. According to the comprehensive analysis of various indicators of various varieties, Changlin No.4, No.23, No.40 and No.55 varieties had the characteristics of high yield, high quality, adaptability and resistance, and could be popularized as the main varieties in Suichang county.
