The results from the evaluation of apricot seedlings for resistance to the plum pox potyvirus (sharka) are presented. The susceptibility of 291 seedlings from 19 different crosses, most of them between resistant and susceptible cultivars, was determined. The results obtained seem to indicate that the resistance to plum pox potyvirus in apricot is controlled by a single gene, where resistance would be a dominant trait and the resistant parents used would be heterozygous for this trait. Since the resistance appeared to behave as a quantitative trait during the evaluation process, the hypothesis of a monogenic control is discussed.
