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

Abstract

Flax (Linum usitatissimum L.) is an important crop for source of with the different uses of oil and ber. In addition, ax, 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 agromorphological traits as well as, assessed genetic diversity through 16 loci strong amplicons SSR markers. According to the ndings agronomic parameters; quality analyzes were performed to for promising varieties. The quality characteristics of the related ber varieties were determined with the help of Scanning Electron Microscopy (SEM) and strength devices. As a result; It has been observed that the Eckendor 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 ndings 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 ax germplasm.

How growing conditions are influential on the agronomic attributes and fiber-related quality parameters of flax (Linum usitatissimum L.) fibers: A seismomorphogenesis approach

“…Its also an important cultivated plant grown for its fiber and oil-rich seeds (Choudhary et al, 2017;Saroha et al, 2022). Mechanical conditioning is the deliberate application of physical stimulation and stress to control the growth and quality of plants (Koçak et al, 2023). Flax fiber has always been used for textile production.…”

“…Seismomorphogenesis causes changes in plant characteristics such as stem diameter, fiber quality or chlorophyll content, with different responses to observations made between species. In addition to causing morphological and mechanical changes in plants, seismomorphogenesis has generally been reported to result in a significant increase in crop yield when plants are grown in the greenhouse under optimum conditions (Koçak et al, 2023). Flax is an industrial crop usually grown in the field and changes in morphology and fiber yield are expected when grown under much milder windy conditions.…”
