Crop Academy of Heilongjiang University / Sugar Beet Research Institute of Chinese Academy of Agricultural Sciences;Key Laboratory of Sugar Beet Genetic Breeding/Heilongjiang University;Key Laboratory of North Sugar Crop Resource and Utilization,Chinese Academy of Agricultural Sciences通过对来自12个国家的247份甜菜种质资源遗的16个描述性状及10个数量性状进行了遗传多样性进行了分析, 结果表明:16个描述型性状均表现出不同程度的遗传差异,多样性指数在0.4806与1.5230之间,平均值为0.8608,其中根肉色多样性指数最小,生长势的多样性指数最大;10个数值型性状的变异系数在1.29%~7.08%之间,平均为3.57%,a-N含量最小,叶片数最大;。对不同国家甜菜种质资源的表型遗传差异进行了分析遗传差异大小为中国>荷兰>美国>瑞典>日本>德国>匈牙利>波兰>俄罗斯>丹麦>法国>比利时。应用SPSS22.0对247份材料表型进行了的聚类分析表明,在阈值为7.5时把材料分为5类,每个国家在五个分类中所占的比例均不同。鉴定筛选出的15份丰产资源和15份高糖资源,可在育种中做为品种产量改良及提高含糖率的亲本材料。
A total of 247 accessions of sugar beet were collected from 12 countries and 26 traits including 16 descriptive and 10 numerical characteristics were tested. The results indicated that In the descriptive characteristics, 16 descriptive properties had showed the genetic differences and the genetic diversity index ranged from 0.4806to 1.5230 with the average of 0.8608.The smallest and the largest diversity index values were observed in root nude and growth vigor, respectively. The coefficient of variation of 10 numeric characters was between 1.29% and 7.08% with the average of 3.57%, the content of a-N was the smallest and the number of leaves was the largest. The phenotypes of genetic differences were analyzed between different countries.Thecountries. The genetic diversity and CV of phenotypic traits showed a tendency of China>Netherlands>America>Sweden>Japan>Germany>Hungary>Poland>Russia> Denmark>France>Belgium.247 sugar beet varieties were divided into 5 groups by cluster analysis of phenotype traits at 7.5 genetic distances by software SPSS22.0. Every country showed difference in the proportion of all of the five classifications. 15 high-yield resources and 15 high sugar resources were screened out, which could be used as the parent material for improving yield and sugar content in breeding.
