Abstract

This study was conducted to analyze the extent of phenotypic diversity of a collection consisting of 200 Moroccan barley landraces, conserved ex-situ in the INRA Genebank, on the basis of 12 morphological characters using diversity indices and multivariate analysis. The Shannon-Weaver index (H’) showed a strong variation for all the studied traits. The H’ mean for the entire collection was 0.63. In addition, the multiple component analysis (MCA) structured the observed diversity into two large groups according to the origin and geographic proximity of each accession. The first group consists mainly of barley accessions from the Atlas and Rif mountains and the other group is composed of accessions from other agro-ecological regions of Morocco. This diversity could be exploited for the development of varieties with multiple uses.

Keywords: Phenotypic diversity, landraces, ex-situ conservation, valorization, genebank, barley.
