摘要：[目的]对长江中下游区板栗主要栽培品种果实性状进行综合评价,为筛选综合性状优良且适于浙江省种植推广的板栗品种提供理论依据。[方法]以长江中下游区25个板栗主栽品种及5个有代表性的北方板栗品种为材料,对其果实表型和品质性状进行连续测定和统计分析,并采用主成分分析和灰色关联度分析法进行综合评价。[结果]果实表型和品质存在不同程度的变异,变异系数范围为7.85%~41.20%,品质性状较表型性状变异更广泛;各指标间分别有23对和18对相关性达到极显著(P<0.01)和显著水平(P<0.05),果实表型与品质性状间存在一定的关联性。主成分分析得出:前5个主成分累计贡献率达79.25%,保留了供试板栗品种果实表型和品质性状大部分信息。灰色关联度分析显示:各性状权重值差异明显,其中,钾含量权重系数最大,总黄酮含量权重系数最小。2种分析方法得出的30个板栗品种果实性状综合表现排序总体趋势较一致,品种综合得分值相关系数为0.7621,达极显著水平。[结论]2种分析方法得出乌壳栗、浅刺大板栗、玫瑰红、八月红、处暑红、九月寒6个长江中下游区板栗品种综合得分值均排在前列,其果实性状综合表现优良,可作为浙江省种植推广的主要参考品种。
[Objective]To evaluate the fruit traits of main Chinese chestnut(Castanea mollissima)cultivars from the middle and lower reaches of the Yangtze River and provide references for the selection of chestnut cultivars with excellent comprehensive performance and suitable for planting and promoting in Zhejiang Province.[Method]Twentyfive main Chinese chestnut cultivars in the middle and lower reaches of the Yangtze River and five representative northern Chinese chestnut cultivars were used as materials,their fruit phenotype and quality traits were continuously measured and statistically analyzed.Then comprehensive evaluation was performed by principal component analysis and grey correlation analysis.[Result]Twenty traits of fruit phenotype and quality had different degrees of variation,and the coefficient of variation ranged from 7.85%to 41.20%.There were 23 pairs and 18 pairs of correlation among all traits reached extremely significant(P<0.01)and significant level(P<0.05),respectively.There was a certain correlation between the fruit phenotype and the quality traits.The cumulative contribution rate of the top five principal components was 79.25%,which retained most of the information of fruit phenotype and quality traits.Grey correlation analysis showed that there were significant differences in the weight values of each trait,in which the weight coefficient of potassium content was the largest and the weight coefficient of total flavonoids content was the smallest.The overall trend of the comprehensive performance ranking of the 30 Chinese chestnut cultivars performed by the two analysis methods was relatively consistent.The correlation coefficient of the comprehensive score of the cultivars by the two analysis was 0.7621,which reached a very significant level.[Conclusion]Six Chinese chestnut cultivars from the middle and lower reaches of the Yangtze River are ranked in the top by the two analysis,the comprehensive performance of their fruit traits is excellent,so the six cultivars can be popularized as the main cultivar in Zhejiang Province.
