Abstract
In order to investigate genetic diversity of two flax species, 50 genotypes were evaluated. The results showed that there was significant difference between two subspecies and also among different regions in subspecies for some seed yield components and Us subspecies was superior than Md for number of capsules/plant but Md subspecies had more 1000 seed weight. Genetic variation in each region was different depending on the trait. Genetic variation ranged for number of capsules/plant from13.9 to 81.7, for number of seed/capsules from 5.4 to 9.22 and for 1000seed weight from 2.5 to 6.4 gram. Seed yield/plant varied from 0.3 to 9.06 gram and seed yield ranged from 188.7to 1453 kg/ha in Norway1005 and Lybia1686 genotypes, respectively, indicating the existence of genetic potential to improve important traits in flax. Cluster analysis classified genotypes into six groups. Genotypes within group one having highest capsule/plant along with genotypes within group two and three had high seed yield/plant. Number of capsules/plant showed highest genetic correlation due to high direct effects along with negative indirect effect through 1000 seed weight on seed yield/plant
