摘　　要：该研究对搜集的99份甜樱桃品种叶长、叶宽、花冠直径、果形、果皮颜色、单果重、果实纵横径、果柄长、可溶性固形物含量、风味、硬度等重要性状进行了统计分析,结果表明,单果重和果柄长的变异系数较大,可溶性固形物含量变异系数最小;平均单果重与果实纵径及横径呈极显著正相关,与叶长及叶宽呈显著正相关;甜樱桃果皮颜色以紫红色居多,占统计品种的46%;果形以心脏形居多,占统计品种的46%;风味以酸甜型为主,占统计品种的64%;果实硬度以脆、硬为主,占统计品种的52%。研究结果为甜樱桃育种目标的制定、亲本选择提供建议,为甜樱桃品种的研究和育种工作提供参考。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.
