Characterization of Nepalese Bread Wheat Landraces Based on Morpho-Phenological and Agronomic Traits

Due to the presence of valuable genes that contribute a variety functional traits, landraces kept in Genebank can be extremely important wheat breeding. A study was conducted based on agro-morphological traits Nepalese bread explore genetic diversity among them. Using replicated rod row design, 200 were evaluated during winter season 2018 and 2019 at Khumaltar, Lalitpur, Nepal. The degree variations determined using univariate multivariate statistical tools. Shannon-Weaver index (H’) showed wide range studied landraces, ranging from 0.55 0.91 quantitative 0.63 0.85 qualitative traits.Principal component (PC) analysis with an eigenvalue greater than 1 reveals 68% variability for is contributed by first five principal components whereas 67% governed four components. UPGMA (Unweighted pair-groups methods through arithmetic average) clustered 202 into groups according charterers.Identified advantageous adaptive within accessions, will used breeders crosses breeding or directly farmers.
