Comprehensive Analysis and Evaluation of Agronomic Characters of 50 Chenopodium Quinoa Germplasm Resources
摘要
Abstract
In order to screen high-quality quinoa germplasm suitable for Hohhot area,50 quinoa germplasm resources were selected as experimental materials,and their agronomic characters were comprehensively analyzed and evaluated by correlation analysis,principal component analysis and cluster analysis,through observing their growth period,plant height,main stem diameter,leaf length,leaf width,effective panicles per plant,main branch panicle length,grain weight per plant,1 000-grain weight and spike color etc.The results showed that there were abundant variations in the agronomic characters of quinoa,and the coefficient of variation ranged from 4.59%to 62.59%;the grain weight per plant was significantly positively correlated with the main stem diameter and effective panicles per plant(P<0.01),and significantly positively correlated with the plant height(P<0.05);4 principal components were selected by principal component analysis,and the cumulative contribution rate was 78.518%.Q-type cluster analysis was carried out on 50 quinoa germplasm resources by class average method.When the distance between classes was 5,the tested quinoa germplasm resources were divided into 6 groups.Class Ⅰ germplasm was abundant,class Ⅱ could be used as landscape germplasm resources,class Ⅲ could develop high-quality forage resources.class Ⅳ could continue to be planted for screening tests,class Ⅴ was high-yielding quinoa germplasm,class Ⅵ was dwarf and small quinoa germplasm material.The research results provided theoretical basis and material support for quinoa high-quality germplasm breeding.关键词
