| This study presents a statistical analysis of key traits in 99 sweet cherry varieties, including leaf length, leaf width, flower diameter, fruit shape, skin color, individual fruit weight, fruit length-to-width ratio, fruit stem length, soluble solid content, flavor, and fruit hardness. The results indicated that the coefficient of variation for individual fruit weight and fruit stem length was relatively high, while the coefficient of variation for soluble solid content was the lowest. A highly significant positive correlation was found between average individual fruit weight and both fruit length and width, and a significant positive correlation was observed with leaf length and width. Purple-red was the most common fruit skin color, accounting for 46% of the varieties. Heart-shaped fruit was the predominant shape, also representing 46% of the varieties. The majority of varieties (64%) had a sweet-sour flavor, while 52% of the varieties were characterized by a crisp and firm texture. These study provides recommendations for breeding objectives and parent selection in sweet cherry, as well as references for the research and breeding of sweet cherry varieties. |
