Phenotypic diversity of date palm cultivars (Phoenix dactylifera L.) from Algeria

The aim of this work is to evaluate the phenotypic diversity of date palm (Phoenix dactylifera L.). This study shows that Biskra region has an interesting biodiversity. This latest was conducted during the growing palm groves since 3 years (2010, 2011 and 2012) in Biskra, on 89 date palm varieties,...
