| Abstract:
Culture of seedlings in different locations in Spain has resulted in the existence of genetically distinct local populations. A description of the characteristics of six selected clones from two Spanish native populations (Gorga and Cofrentes) located in Valencia, Spain is presented. The selected clones were non-melting type, fruits were highly colored yellow, clingstone, with high solids content and low acidity. The fruit development period ranged between 162 for the earliest clone to 228 days for the latest. SSR molecular markers have been tested for identification of clones belonging to the same population. Ten flanking microsatellite sequences showed polymorphism in the set of cultivars studied. The polymorphic loci allowed to identify all the clones studied, except two. SSR markers resulted an efficient tool in terms of germplasm identification of species with low genetic variability such as peach. | |
