Abstract


Understanding the genetic diversity of linseed (Linum usitatissimum L.) is important for the continued improvement of this crop as well as for its development in the agricultural system. Therefore, to generate adequate information on genetic diversity of linseed, 49 sample accessions collected from five regions of Ethiopia along with 15 cultivars were used in this study with the objectives of investigating the morphological diversity between and within germplasm. Experiment was conducted at Sinana Agricultural Research Center, South Eastern Ethiopia. Treatments were arranged in 8 x 8 simple lattice square design with two replications. The Agro-morphological data were subjected to the analysis of variance. Highly significant variation for all the characters except for number of seeds per capsule and biomass. Clustering pattern and correlation matrix among and within Ethiopian linseed landraces and non-native cultivars were discussed. Furthermore, there were ample variations between and within Ethiopian linseed landraces and non-native cultivars, implying high chances for current and future genetic improvements in which desirable traits could be incorporated to new cultivars.
