Abstract

Olive is known to be an allogamous species. The aim of this study was to estimate the magnitude of cross-pollination rate using microsatellite simple sequence repeats (SSR) and inter simple sequence repeats (ISSR) molecular markers in olive genotypes. The DNA from maternal plants and 23 progenies of two different accessions, Ascolano USA and MGS GRAP541 were extracted and screened with two microsatellite and ten ISSR markers. The outcrossing rate and other related parameters were analyzed using the MLTR application. The set of estimates, individually and collectively, support the hypothesis of frequent allogamy in both olive genotypes evaluated, with high rates of outcrossing in both markers.
