Morphological and molecular characterization of flax (Linum usitatissimum L.) accessions obtained from different locations in Turkey

Flax ( Linum usitatissimum L.) is an important crop for source of with the different uses of oil and fiber. In addition, flax, which has an important place in the world and our country, has a multi-purpose use area. The objectives of the current research were to assess genetic diversity and patterns of relationships among the relative cultivar/genotypes through morphological traits and microsatellite (SSR) markers. The present study evaluated genetic diversity and association patterns among 63 cultivar/genotypes through 19 morphological traits, oil yield (18.033%) and fatty acid compositions. The relative agro-morphological traits as well as, assessed genetic diversity through 16 loci strong amplicons SSR markers. According to the findings agronomic parameters; quality analyzes were performed to for promising varieties. The quality characteristics of the related fiber varieties were determined with the help of Scanning Electron Microscopy (SEM) and strength devices. As a result; It has been observed that the Eckendorfi can be promising. Principal Component Analysis (PCA) (JAMOVI 2022) performed to relevant parameters. Additionally, UPGMA (Arithmetic Mean Unweighted Double Group Method) is an individual marker system used to create the dendrogram. The average Polymorphic Information Content (PIC) values were recorded as (0.689), while the least and largest loci with allele dimensions were Lu9 (2) and Lu19-Lua613(6) respectively. These findings of the present study were supported by the results of the principal coordinate analysis. Morphological markers made use of in the study were found to be complementary to microsatellite-based markers in decoding, the genetic diversity and population structure of the flax germplasm.
