Abstract: Variation condition, distribution rule and correlation of main quantitative character of 82 open ground strawberry varieties(or lines)were studied and analyzed. The results showed that: Fruit firmness, soluble solid content, mean single fruit weight, max single fruit weight and yield of per plant were normal distribution respectively. The variation of different character is differrent. Correlation analysis showed there were notable positive relationship between fruit firmness and mean single fruit weight, and definitely positive relationship between fruit firmness and yield of per plant, and definitely positive relationship between mean single fruit weight and max single fruit weight and yield of per plant, and definitely positive relationship between max single fruit weight and yield of per plant. The research provided basis for preselection of parent and hybrid offspring of strawberry breeding.

Key words: Straw berry, Quantitative characters, Variation, Correlation analysis
