Abstract: In order to screen out blueberry varieties suitable for planting in Suichang county, four blueberry varieties, namely Sharpblue, O'Neal, Britewell and Climax were selected as test materials by using a complete randomized block design. After five years of planting, the tree height, crown width and yield were compared. The results showed that (1) the Britewell and Sharpblue varieties were obviously superior to the other two varieties, with taller and more luxuriant values. For the Britewell and Sharpblue varieties, the tree height was 149.00 cm and 142.14 cm respectively, the crown width was 162.00 cm and 159.11 cm respectively, and the yield in 200 m² was 518.70 kg and 505.40 kg respectively. (2) The O'Neal variety had the largest average single fruit diameter and mass (1.52 cm and 1.59 g), but had the lowest yield per unit area (228.90 kg). (3) The suitable planting altitude was 800−1 050 m, and it was necessary to do shading and cooling when they were planted at the altitude of 320 m in summer from July to August. In summary, the Britewell and Sharpblue varieties can be planted and promoted as the main cultivars at the altitude of 800−1 050 m in Suichang county.
