The result of variation analysis of 81 introduced flax germplasm resources of main agronomic characters showed that there was significant genetic diversity. Through the factor analysis,we classified three factors,yield factor,seeds per capsule factor and plant shape factor,which could represent the 7 characters. The correlation analysis determined the relationship among the characters. By cluster analysis,the 81 materials could be classified into 3 groups,which provided the basis for the different breeding ...
