In the conditions of the Republic of Belarus there were presented the results of estimation of a field resistance to a scab within five research years of apple (Malus) hybrid fund. This fund has passed the selection for a scab resistance on an artificial infection background of the pathogen V. inaequalis. The results of comparative efficiency use of apple introduced cultivars as initial forms – donors of various monoresistant to the disease genes such as Rvi4, Rvi6, Rvi10 are introduced. In each family there were singled out the genotypes which affect was not exceeded 2 points in the conditions of an annual rigid infection background of the causal organism of a scab. Use of the cultivars Reka (gene Rvi4) and Redkroft (gene Rvi6) in a breeding work appeared to be the most productive. In their hybrid offspring there were singled out 74 and 58 % respectively of high resistant and resistant to the disease genotypes of a new generation possessing scab resistance stable in time.
