Abstract: The data about agronomic characters of 19 flax clutivars were analysed with a statistical software SPSS 18.0.The results showed large aberrance coefficient of sub-stem per plant,capsules per plant and capsules weight of per plant.There were significant positive correlation between plant height and Length of craft,between sub-stem per plant and capsules per plant,between capsules weight of per plant and capsules per plant,and between capsules weight of per plant and sub-stem per plant.but 1000-seed weight had a significant negative correlation with plant height.The 19 flax cultivars were classified to 4 groups based on integrated characteristics.Group 1 and group 3 had excellent agronomic traits and were recommended for expansion.
