Description Genetic diversity in a set of 20 improved bread wheat cultivars released in Morocco since 1980s, along
with 8 exotic bread wheat cultivars, were characterized by employing 14 polymorphic microsatellite markers. A
total of 59 alleles (Mean=4.21) in Moroccan cultivars and 53 alleles (Mean=3.78) in exotic cultivars were
detected. Genetic diversity at 14 microsatellite loci varied from 0 to 0.895 (Mean=0.576) for 20 Moroccan
cultivars and from 0.25 to 0.928 (Mean=0.683) for the exotic cultivars. The genetic distance among the cultivars
ranged from 0.143 to 1.00. Using the 14 microsatellite markers, all the bread wheat cultivars could be
distinguished for reliable identification, characterization, and diversity analysis. Total number of alleles
decreased in the cultivars developed during 1990s (8.3%) compared with that of 1980s. The AMOVA results
suggest that change in the cultivar genetic diversity among different decadal groups of bread wheat was very
small and non-significant, indicating no significant reduction in over all genetic diversity due to breeding in
recent times.
