The developed in the conditions of the Republic of Belarus method of rapid assessment apple (Malus) hybrids by parameters of their fruiting and harvest quality allows in course of the primary cultivar evaluation to select more precisely the investigated hybrids of apple by the realization of the genetic potential of productivity and fruit quality. The presented technique provides a shortening testing of promising hybrids for selection into the elite and state evaluation in average of 4-5 years, as well as initial testing of new introduced varieties and hybrids of apple. Based on the data for the primary study of apple varieties and hybrids it was efficient to use rootstock 62-396 with planting schemes 4.5 x 2.5 m - for strong-growing varieties, 4.0 x 2.0 m – for average height ones, 4.0 x 1 5 m – low height varieties. Rootstock PB-4 can be used with a planting scheme: 3.0 x 1.5 m - for high- and medium-height varieties, 3.0 x 1.0 m- low height varieties, but in this case it is necessary to consider the support structures in the form of a trellis and irrigation, as well as special techniques of crown formation.
