摘要:

以47份杨梅种质资源为试验材料,测定单果质量、可食率、可溶性固形物(TSS)、总糖、黄酮含量、维生素C、果皮色泽等16项指标,开展果实品质差异分析与性状相关性分析,并基于主成分分析对各种质果实品质进行综合评价。结果表明,杨梅种质的各项果实品质性状均存在不同程度的变异,其中氨基酸含量变异系数最大,为60.29%,单果质量、可滴定酸、色差值a*、色泽参数C的变异系数也处于较高水平,分别为41.29%、36.07%、37.82%和37.01%;而果形指数、可食率、果实硬度性状相对稳定,变异系数仅为2.51%、1.94%和6.28%。大部分果实品质性状存在显著差异,且各品质性状间存在不同程度的相关性。从16项果实品质指标共筛选到6个主成分,累计方差贡献率达到78.61%,结合各主成分载荷值,筛选出色差值a*、单果质量、果实硬度以及TSS、氨基酸、黄酮类、可滴定酸、维生素C含量等8项为核心指标,建立了浙南杨梅资源果实品质的综合评价模型。基于相关性分析与主成分综合评价结果,筛选出‘东魁’‘大东魁’‘响动岩1号’‘苍南1号’‘茶山3号’‘大荸荠’‘早炭’‘丁硕’‘高楼早’‘苍南2号’等一批果形大、糖度高、风味浓的优质杨梅种质,为浙南地区杨梅优异种质创新及新品种选育提供理论依据与资源支撑。

Abstract:

Forty-seven Chinese bayberry germplasm resources were used as experimental materials. Sixteen indicators including single fruit weight,edible rate,total soluble solids(TSS),total sugar,flavonoid content,vitamin C content and peel color were measured. Difference analysis and correlation analysis of fruit quality were carried out,and principal component analysis(PCA)was applied to comprehensively evaluate the fruit quality of each germplasm. The results showed that all fruit quality traits of Chinese bayberry germplasms varied to different degrees. Among them,amino acid content had the highest coefficient of variation(CV)of 60.29%. Single fruit weight,titratable acid,color parameter a* and color parameter C also exhibited high CV of 41.29%,36.07%,37.82% and 37.01%,respectively. In contrast,fruit shape index,edible rate and fruit hardness showed relatively stable variation,with CV of only 2.51%,1.94% and 6.28%. Difference analysis revealed that most fruit quality traits differed significantly among bayberry germplasms,and correlations of varying degrees existed between quality traits. Principal component analysis extracted six principal components from the 16 fruit quality indicators,with a cumulative variance contribution rate of 78.61%. According to the loading values of each principal component,eight core indicators were screened out,namely color parameter a*,single fruit weight,fruit hardness,TSS,amino acid content,flavonoid content,titratable acid and vitamin C content. On this basis,a comprehensive evaluation model for fruit quality of Chinese bayberry germplasm resources in southern Zhejiang was established. Based on the results of correlation analysis and PCA comprehensive evaluation,a set of superior Chinese bayberry germplasms characterized by large fruit size,high sugar content and rich flavor were screened,including‘Dongkui’‘Dadongkui’‘Xiangdongyan 1’‘Cangnan 1’‘Chashan 3’‘Dabiqi’‘Zaotan’‘Dingshuo’‘Gaolouzao’and‘Cangnan 2’. This study provides theoretical basis and germplasm support for the excavation of elite germplasms,germplasm innovation and new cultivar breeding of Chinese bayberry in southern Zhejiang.
