Elucidating Diversity of Linseed (Linum usitatissimum) Germplasms by Applying DUS Guideline to Examine Morphological Features

Flax, or Linum usitatissimum, is a multipurpose crop that may be produced in a variety of climates for use in industry, feed, fibre, and food. It is crucial to characterize and assess an array of genotypes to comprehend the potential of linseed in agriculture. The present investigation focused on agro-morphological characteristics to identify the best germplasm that may be utilized as future donors for linseed breeding. The goal of this study was to find the best germplasm to be used as future donors for linseed breeding by focusing on agro-morphological traits. In the current study, an expanded design was used to test 92 genotypes in total, both alien and native, throughout the course of two seasons, Rabi 2022-23 and Rabi 2023-24. The ninety-two genotypes were found to be organized into seven primary clusters by cluster analysis. Cluster I consist of twenty-four genotypes. Whereas cluster II and cluster III each encompass one genotype i.e., IC394118 and IC0599415 respectively. While cluster IV consists of seventeen genotypes, cluster V contain thirty-one genotypes. Cluster VI consist of seven genotypes. Whereas cluster VII which is the last cluster included eleven genotypes. A broad variation of genetic diversity was found using cluster analysis. The findings of this study open the door for focused breeding initiatives and environmentally friendly farming methods by offering insightful information about the genetic diversity and phenotypic variability of linseed.
