Abstract
A field experiment was conducted at Kulumsa Agricultural Research Center in order to estimate the extent of genetic variation in Ethiopian mustard (Brassica carinata A. Braun). In this study, genetic diversity in 60 Ethiopian mustard genotypes, collected from 16 regions of Ethiopia, were assessed using the techniques of cluster and principal component analyses based on 16 traits. All traits were significantly (P and 19% of the variations, respectively. Days to flowering, days to maturity, seed yield/plot, oil yield/plot and biomass/plot were the most important traits contributing to the total variation of the first principal component, implying the existence of great potential to improve these traits through selection.

为了估计埃塞俄比亚芥菜(Brassica carinata A. Braun)遗传变异的程度,在Kulumsa农业研究中心进行了一项田间试验。本研究采用聚类分析和主成分分析技术,对来自埃塞俄比亚16个地区的60个芥菜基因型的遗传多样性进行了分析。所有性状的变异率分别为显著(P)和显著(19%)。花期、成熟期、产子量/畦、产油量/畦和生物量/畦是影响第一主成分总变异的最重要性状,表明这些性状存在很大的选择潜力。关键词:芸苔;聚类分析;埃塞俄比亚芥;遗传多样性
