Genetic variability of hull-less barley accessions based on molecular and quantitative data

Abstract: -The objective of this work was to characterize and quantify the genetic, molecular, and agronomic variability of hull-less barley genotypes, for the selection of parents and identification of genotypes adapted to the irrigated production system in the Brazilian Cerrado. Eighteen hull-less barley accessions were evaluated, and three covered barley accessions served as reference. The characterization was based on 157 RAPD molecular markers and ten agronomic traits. Genetic distance matrices were obtained based … Show more

“…These studies are important for obtaining a wider knowledge of elite and promising barley in irrigated cultivation in the Cerrado. For the characteristics TSE, Height and DH, the CEV values were close to those obtained by Sayd et al (2017) and Sayd, Amabile, Faleiro, and Bellon (2015), who only collected the parameters at different sites.…”

“…In another study, eight genotypes from various regions of the world showed 0.61 mean genetic dissimilarity (Drine et al, 2016). An evaluation using RAPD markers, in the Brazilian Cerrado, showed 0.28 mean genetic dissimilarity for 21 naked barley genotypes from different continents (Sayd et al, 2015). In this scenario, the genetic dissimilarity values obtained in the present study show that the genotypes have a considerable degree of variability, although most of them are of Colombian origin and have been selected for the same agronomic characteristics.…”

“…Characterization of large numbers of test samples is restricted by labour costs, the area required, financial resources and the number of seeds. Molecular markers have been used to characterize barley accessions however these tools cannot replace morpho‐agronomic characterization. The use of cost‐effective elaborate designs to reduce experimental error for morpho‐agronomic characterization has been limited.…”
