Abstract

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.

Key words: Chenopodium quinoa, germplasm resources, agronomic traits, comprehensive analysis

摘要：

为筛选适宜呼和浩特地区的优异藜麦种质，选用50份藜麦种质资源为试验材料，通过考察其生育期、株高、主茎直径、叶长、叶宽、单株有效穗数、主枝穗长、单株粒重、千粒重、穗色等农艺性状，采用相关性分析、主成分分析及聚类分析等对其农艺性状进行综合分析与评价。结果表明，藜麦农艺性状变异丰富，变异系数介于4.59%~62.59%；单株粒重与主茎直径、单株有效穗数呈极显著正相关（P<0.01），与株高呈显著正相关（P<0.05）；利用主成分分析共筛选出4个主成分，累计贡献率达78.518%。采用类平均法对50份试验材料进行Q型聚类分析，当类间距离为5时，将供试材料分为6个类群，第Ⅰ类种质数量较多，第Ⅱ类可作为景观种质资源，第Ⅲ类可发展优质牧草资源，第Ⅳ类可继续进行种植筛选试验，第Ⅴ类为高产型藜麦种质，第Ⅵ类为植株矮小型藜麦种质材料。研究结果为藜麦优异种质选育提供了理论依据及材料支持。
