title: Analyse de la diversité de processus de développement racinaire chez les Prunus : aptitude au bouturage et réponses à la contrainte hydrique
abstract: In breeding programs of Prunus rootstocks the aim is to use the existing genetic variabilitywithin Prunus species in order to create new rootstock genotypes with excellent agronomic traits, andimproved resistance to biotic and abiotic stresses.Exploitation of the genetic variability is based on the evaluation of phenotypic variation amongindividuals within genetic collections for desirable traits. This make possible to select specificgenotypes to improve a given trait.This study consists of two
