Analysis of Sugar and Acid Components in Table Grape Germplasms from the Hebei Grape Germplasm Repository
摘要
Abstract
This study systematically analyzed the characteristics and inheritance patterns of sugar and acid components in table grape germplasms from the Hebei Grape Germplasm Repository.The results showed that fructose exhibited a higher coefficient of variation(CV=42.2%in 2023,CV=59.7%in 2024)than glucose(CV=36.2%in 2023,CV=45.0%in 2024),indicating greater genetic diversity.Among organic acids,malic acid showed the highest coefficient of variation(CV=61.3%in 2023,CV=71.4%in 2024),indicating its key role in shaping fruit acidity diversity.Correlation analysis revealed a highly significant positive correlation between fructose and glucose across years,with strong synergy within the same year(r＞0.89),suggesting that their accumulation is regulated by stable genetic control and potentially shared metabolic pathways.In contrast,interannual stability and interrelationships among organic acids were more complex:tartaric acid and malic acid were strongly genetically controlled,while oxalic acid was more susceptible to environmental influences.Principal component analysis(based on 2023 data)indicated that the"sugar-acid trade-off"was the main driver of germplasm differentiation(PC1 contribution rate:43.2%).Cluster analysis based on sugar and acid composition categorized the germplasms into four groups,among which the high-sugar,low-acid type(Cluster 1,89 accessions)exhibited superior table grape quality,and the low-sugar,high-acid type(Cluster 2,3 accessions)showed potential for specific processing applications.This study provides valuable germplasm resources and a theoretical foundation for flavor quality improvement and breeding of table grapes in North China.关键词
