Major goal in the selection for scab-resistance is early diagnostics of resistance of breeding material, which is performed by mandatory application of artificial media. The article concerns the results of evaluation on scab-resistance apple seedlings in the artificial infection media. At research carrying out it is established the low germination of seeds received as a result of crossings of varieties and hybrids of interspecific origin, because of the incomplete fertilization shown at incompatibility of parental forms, and also low temperature of air during flowering. Efficiency of selection on stability to scab at early stages of development seedlings on an artificial infectious background depends on inoculum type. For creation of an artificial background at estimation of selection material of an apple-tree on stability to scab the best result is received in case of use of fresh leaves and preserved. The greatest output of steady seedlings is received in hybrid families in which both parental forms are sources of immunity to scab: Imant, Pospekh, Darunak, Belorusskoe sladkoe, Start, 86-54/133, 86-56/121, 86-54/137, 86-55/53 and 88-24/6
