摘　　要：针对山黧豆苗菜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29份山黧豆品种资源作为供试材料,模拟中农绿谷芽苗菜研究院山黧豆苗的培育工艺与条件,根据山黧豆及山黧豆苗的8项性状指标,采用基本统计量分析、K-均值聚类分析和相关性分析对山黧豆苗菜用特性进行初步评价。结果表明,各性状中苗菜产出量的变异最大,变异系数为24.42%。29份山黧豆品种资源可划分为5个类群。其中一类具有小粒、高苗菜产出量、高可溶性蛋白含量、高VC含量的特征。苗长与苗菜产出量和种皮的光滑程度极显著正相关;苗菜产出量与品种种皮光滑程度极显著正相关,与百粒重显著负相关。本研究显示,鉴定与评价山黧豆品种苗菜用特性优劣时,应重点考虑苗菜产出量并兼顾营养品质和感官品质,优先筛选苗菜产出量≥1.01的品种作为芽用备选资源。初步筛选出甘肃张掖山黧豆、白香山黧豆、阿杂山黧豆-2共3份优异资源,供进一步研究。There has been a lack of certainly and integrity in sprout characteristics evaluation of grasspea and breed quality identification for a long time.In this study,29 germplasm resources of grasspea from diffident locations of China were collected as the materials.They were cultivated as the method described by ZNLG institute.An preliminary study has been performed by basic statistic analysis,K-means clustering analysis and correlation analysis on the eight traits of grasspea and grasspea sprouts.The results showed that variation coefficient of bean sprouts output reached 24.42% which was larger than those of other traits.Twenty-nine accessions of grasspea species were divided into 5 groups.Characters of group one were small grain,high seedling production,high soluble protein content,and high VC content.Length of grasspea sprouts was significantly correlated with bean sprouts output（P〈0.01）,and was significantly correlated with smoothness of seed skin（P〈0.01）.Bean sprouts output was significantly correlated with smoothness of seed skin（P〈0.01）,but was negatively correlated with kernel weight（P〈0.01）.To screen and evaluate the resources of grasspea for sprouts,sprouts output should be more important than other traits,and the values of them should be larger than 1.01g/g.In this study,grasspea of Gansu Zhangye,White fragrant grasspea,and Aza grasspea-2 were selected as excellent resources for further study.
