Abstract: Genetic diversity is an essential component of selection and conservation.Morphological descriptors are the primary tools for germplasm management.The aim of this study was to determine the morphological variability of a collection of genotypes of Tiger Nuts (Cyperus esculentus L.) in Burkina Faso.A total of 44 genotypes were evaluated using an apha lattice block design with three replications.Each replication consisted of two blocks with 22 genotypes per block.Data were collected on 5 qualitative and 11 quantitative variables.The data collected were subjected to descriptive, variance, bivariate and multivariate analyses.The results of the study revealed morphological variability between genotypes.Ten morphological descriptors (tuber shape, tuber colour, inflorescence, leaf width, number and weight of tubers per plant, tuber yield, weight of 100 tubers, length and diameter tubers) discriminate the genotypes studied.The genotypes were divided into five distinct groups, irrespective of geographical origin.This structuring has enabled to distinguish groups I and II, constitute of genotypes of average agronomic performance.Group III has grouped genotypes with broad leaves.Group IV is composed of genotypes producing a large number of tubers per plant and of small size.Group V contains genotypes with large tubers and higher yields.The results of this study could be used to improve Tiger Nuts varieties in Burkina Faso.
