Abstract: To understand the high yield and adaptability characters of different blueberry varieties in Lijiang, Yunnan, and select new blueberry varieties with good-quality and high-yield which are suitable for planting in the region, we compared agronomic characters of 8 rabbiteye blueberry varieties, and assessed the main agronomic traits, including bearing branch number, fruit number per branch, plant height, fruit weight, annual branches, crown breadth, and yield per plant based on grey correlation analysis. The results showed that: with plant yield as reference sequence, and other characters constituted comparison sequence, the grey correlation sequence was bearing branch number> fruit number per branch> plant height> fruit weight> annual branches> crown breadth. Taking the ideal variety as the reference sequence, and the other varieties were compared ones, the grey correlation sequence was‘Baldwin’>’Powderblue’>’Brightwell’>’Premier’>’Climax’>’ Gardenblue’>’Homebell’>’Tifblue’. So, ‘Baldwin’, ‘Powderblue’, ‘Brightwell’ and ‘Premier’ are screened out, which have excellent comprehensive characters and are suitable for planting in Lijiang.
