Flax (. Linum usitatissimum L) is an important oil seed crop with multiple applications including human food, industrial uses and animal feed. Flax improvement requires information on genetic diversity of different traits. In the present study, seed characteristics of flax genotypes were studied in the filed using a simple lattice square design with two replication. The results showed significant differences among the genotypes for the measured characteristics. Seed yield per plant ranged from 0.22 to 1.87 gr. This trait and 1000- seed weight showed a high coefficient of phenotypic and genetic variation. Cluster analysis Keywords : Flax, Genetic variation, Broad-sense heritability, Seed traits
