摘要
通过变异系数、聚类分析和相关性分析等方法,对来自我国16个地区的528份绿豆样品的营养品质多样性进行分析和综合性评价,以期提升绿豆品种的品质并优化选育工作。结果表明所有受试样品的蛋白质含量、淀粉含量、脂肪含量、总多酚含量和总黄酮含量的范围分别是16.14~29.19 g/100 g、34.48~57.68 g/100 g、0.67~1.34 g/100 g、1.63~6.78 mg GAE/g和0.59~2.83 mg RE/g,变异系数范围介于4.49%~22.98%,说明绿豆种质资源存在丰富的变异。结合不同地区营养品质分析和聚类分析发现,湖北地区的绿豆资源以高蛋白为主要特征;吉林地区的绿豆资源以高淀粉为主要特征;山东地区的绿豆资源以高脂肪为主要特征;重庆地区的绿豆资源以高总多酚为主要特征;陕西地区的绿豆资源以高总黄酮为主要特征。相关性分析表明,绿豆资源蛋白质含量、淀粉含量和总黄酮含量与经度均呈正相关,总多酚含量与经度呈负相关,脂肪含量与海拔呈负相关。本研究对绿豆品质育种、筛选高品质绿豆种质资源以及促进绿豆产业的高质量发展具有重要意义。
In order to enhance the quality of mung bean varieties and facilitate precision breeding,the nutritional quality diversity of 528 mung bean samples from 16 regions in China was analyzed,followed by comprehensive evaluation using coefficient of variation,cluster analysis and correlation analysis.The study revealed substantial compositional variation in contents of protein,starch,fat,total polyphenol and total flavonoid that were 16.14-29.19 g/100 g,34.48-57.68 g/100 g,0.67-1.34 g/100 g,1.63-6.78 mg GAE/g and 0.59-2.83 mg RE/g,respectively.The coefficient of variation(CV)ranged from 4.49%to 22.98%,indicating robust genetic diversity.Geographic clustering identified distinct regional nutritional profiles.Accessions from Hubei province were characterized by elevated protein content,accessions from Jilin province were characterized by high starch accumulation,accessions from Shandong province were characterized by increased fat content,accessions from Chongqing were characterized by accumulated higher polyphenols,while accessions from Shaanxi province were mainly characterized by higher flavonoids.Correlation analysis indicated positive trends between longitude and protein content,starch content and total flavonoids content,while total polyphenols content showed a negative correlation with longitude and fat content was negatively correlated with altitude.These findings provide critical insights for precision breeding,optimized germplasm utilization,and value chain development in mung bean production systems.
