Evaluation and Analysis of Major Agronomic Traits in 324 Flax Germplasm Resources
摘要
Abstract
This study used 324 flax germplasm resources as materials,and nine major agronomic traits were measured in a two-year,single-location experiment.Variation analysis,correlation analysis,and principal component analysis were conducted to comprehensively evaluate these traits,aiming to pro-vide germplasm materials and a theoretical basis for flax variety improvement.The results from the two-year experiment showed high consistency:the tested materials exhibited abundant variation and rich ge-netic diversity across all agronomic traits.Correlation analysis indicated that the effects of traits on stem yield ranked as technical length>plant height>stem diameter.Seed yield was positively correlated with thousand-grain weight and negatively correlated with technical length.Principal component analysis from both years revealed that the first three principal components cumulatively explained over 64％ of the total variance,effectively capturing the major genetic variation among the tested germplasms.关键词
