多头切花菊品质性状遗传多样性分析
Genetic diversity analysis in spray cut chrysanthemum based on quality character
摘要
Abstract
Based on quality character analysis,genetic diversity among 15 cultivars of spray cut chrysanthemum were analyzed.12 quality traits showed different degrees of diversity.The variation coefficient of layer of ray floret,ray floret length and branch length was larger,and variation coefficient of leaf length was minimum.Principal component analysis showed that flower characters such as layer of ray floret,flower diameter and ray floret length contributed mainly to the principal components,with stem characters (internode length,stem diameter,and plant height) as a secondary contribution.There were significant and extremely significant correlations between quality characters of spray cut chrysanthemum,and significant positive correlation existed between inflorescence diameter and flower diameter,and ray floret length,between flowering branch number and inflorescence height,and between flower diameter and ray floret length.UPGMA clustering analysis showed that 15 spray cut chrysanthemum cultivars could be classified into 5 major groups by genetic distance at 4.21.关键词
