Description This work evaluated a collection of hundred groundnut (Arachis hypogaea L.) varieties from different
origin using twenty four (24) agro-morphological traits that can help to enhance selection efficiency in
crop improvement. The experiment was carried out at the experimental station of INRAN-Tarna, in the
region of Maradi (Niger) during the rainy season of 2010. Analysis of variance showed a large variability
among varieties for the agro-morphological traits. Principal Component Analysis (PCA), Agglomerative
Hierarchical Clustering (AHC) and Fisher Discriminant Analysis (FDA) revealed that this variability is
structured into four distinct groups. Groups I and II consisted of early varieties that have a high
emergence rate and high pods and seed weight. These groups included mainly local varieties and those
introduced in Niger through seed dissemination. Groups III and IV are composed of late varieties with
large pods while group III had mostly varieties with long leaflets. Understanding the genetic control of
the most discriminating among the studied traits would bring significant contribution to the genetic
improvement of this important crop.
