Abstract :

The characterization of the available genetic resources is of first importance to manage and optimize their preservation and/ or their potential use in breeding programs. Genotypic diversity of 92 apricot germplasms, issued from prospection were characterized with 21 microsatellite markers previously chosen for covering the whole genome and diversity indices, molecular variance analysis, principal component, and cluster analysis were applied to analyze the genetic diversity. The genetic variance explained 3% of the three ecogeographic zones, 10% among the 14 groups and 87% within each genotype group. The structure tests (neighbor-joining tree analysis and PCoA) indicated that the accessions issued from the collection could be separated into two populations (K = 2). The self-compatibility trait could be the main reason for the separation between apricot genotypes. Most of the cultivars issued from cluster I are located in the middle temperate zone (atlas valleys and mountains) of middle and northern of Morocco, while most of the cultivars of subcluster II (47 genotypes) are located in the warm temperate area of south-eastern Morocco highlighting the differential impact in light, and temperature between the two regions on the natural selection process. Information obtained in this study may be useful for apricot breeding improvement programs and it could enable the enlargement of the apricot genotype in the Mediterranean basin scale.
