绿豆品种芽用特性的初步评价

针对绿豆品种芽用特性评价体系不完善和优良品种鉴别不明确的现状,收集我国不同地区的55份绿豆品种及品种资源作为供试材料,模拟工厂化豆芽生产工艺,根据绿豆及绿豆芽的10项性状指标,采用主成分分析、K-均值聚类分析和相关性分析对绿豆芽用特性进行初步评价。结果表明:产量因子和芽用因子的评价贡献要大于营养因子。不同品种绿豆田间单株产量的变异范围较豆芽产出量大,在聚类分析所划分的5个类群中,田间单株产量的差异也较豆芽产出量大。单株产量与百粒重呈极显著正相关。豆芽产出量与百粒重呈极显著负相关,与豆芽下胚轴长呈极显著正相关,与绿豆蛋白质含量呈极显著负相关;评价绿豆品种芽用特性优劣时,应重点考虑品种的单株产量和豆芽产出量、同时兼顾品种的蛋白质含量和豆芽形态等,优先筛选田间单株产量≥12.70,豆芽产出量≥7.75的品种作为芽用备选资源。

Initial evaluation of sprouts characteristics of mung bean varieties

This research based on the status quo that evaluation system of mung bean sprouts characteristics is imperfect and identifying of high-quality breed is indefinite,utilize fifty-five representative resources of mung bean as test materials;simulate factory germination process,use principal component analysis and K-means clustering analysis and correlation analysis to Initial evaluate mung bean sprouts characteristics according to ten traits of mung bean and mung bean sprouts.The results showed that production...
