Diversity Analysis of Agronomic Traits in Different Varieties of Coriander
摘要
Abstract
[Objective]Germplasm resources are an important basis for biological research and genetic breeding of coriander,to reveal the diversity of agronomic traits in various coriander varieties,and screen specific germplasm to lay the foundation for the selection and breeding of new coriander varieties.[Method]In this study,a total of 18 relevant traits of phenotypic traits and physiological indexes of 16 different coriander varieties were studied and evaluated systematically and comprehensively by combin-ing the methods of correlation,principal component and cluster analysis.[Result]The 16 coriander va-rieties showed a high degree of genetic variation,with coefficients of variation ranging f rom 8.52%to 80.29%for the 18 traits.Fresh weight exhibited the highest coefficient of variation,while plant height showed the lowest.Correlation analysis indicated strong interrelationships among the traits,fresh weight had highly significant correlation with plant width(0.945),plant height had a significant negative corre-lation with soluble sugar(-0.578)and negative correlation with soluble protein(-0.367).The principal component analysis showed that the cumulative contribution of the four principal components was 83.401%,which could better reflect the majority of the information of coriander traits.[Conclusion]The 16 corian-der varieties were classified into three groups.Class Ⅰ contained five coriander varieties characterized by strong flavor,small plant size and high internal quality.Class Ⅱ contains ten varieties,which are strong in flavor,medium in size and can be used for essential oil extraction.Class Ⅲ contains one coriander va-riety,characterized by non-fragrant plants,high plant size and high vitamin C content,making it suit-able for further cultivation of high-yield and high-quality coriander.In conclusion,the participating cori-ander varieties have rich diversity in agronomic traits,which can provide an abundant resource for the in-novation of coriander germplasm and the selection and breeding of new varieties.关键词
