    摘要:

    为促进甜樱桃优良新品种的选育,对35份甜樱桃品种(系)果实的10项外观品质和6项内在品质指标的分布频率、变异系数等采用相关性分析、主成分分析和聚类分析进行评价和研究。结果表明,果形、果实缝合线形状、果顶形状等3个描述性性状的辛普森指数分别为0.700、0.561和0.573。13个数值型性状中畸形果率的变异系数最大(95.00%),可食用率的变异系数最小(3.35%)。单果重与果肉重、可食用率呈极显著正相关性,固酸比与pH值呈极显著正相关性,与可滴定酸呈极显著负相关性。聚类分析将甜樱桃品种(系)按照果实品质性状分成4个组群,适用于针对性筛选具有某些优良性状的种质资源。基于上述分析结果表明,‘雷吉纳’、‘交大54号’和‘罗亚理’综合性状优势突出,可作为甜樱桃育种的优良亲本。

    Abstract:

    In order to promote the breeding of new varieties of sweet cherry, the distribution frequency and variation coefficient of 10 external quality and 6 internal quality indexes of 35 sweet cherry varieties (strains) were evaluated and studied by correlation analysis, principal component analysis and cluster analysis. The results showed that the Simpson index of fruit shape, shape of fruit suture and shape of fruit top were 0.700, 0.561 and 0.573, respectively. Among the 13 numerical traits, the coefficient of variation of abnormal fruit rate was the largest (95.00%), and the coefficient of variation of edible rate was the smallest (3.35%). Single fruit weight was positively correlated with fresh core weight and edible rate, solid acid ratio was positively correlated with pH and negatively correlated with titratable acid. The cluster analysis divided sweet cherry varieties (strains) into 4 groups according to fruit quality characters, which was suitable for targeted screening of varieties (strains) with some excellent characters. Based on the above analysis results, the comprehensive characters of 'Regina', 'SJ-54' and 'Royal Lee' have outstanding advantages, and can be used as excellent parents for sweet cherry breeding.
