comparative assessment of genetic diversity of 122 durum wheat genotypes (triticum turgidum l. var. durum) was performed using 73 ssap polymorphic fragments, 123 aflp polymorphic loci and 104 ssr alleles. ssap and aflp data showed a clear demarcation between the cultivars and landraces and ssr data classified cultivars and landraces according to their origin. furthermore, the estimated genetic ...
