The following ways to obtain seedlings with interstems of dwarf rootstocks are presented: growing via budding, via double simultaneous winter grafting, via using both winter grafting and budding, via using both budding and spring grafting, via using both winter and spring grafting. The data of research from CIS and other foreign countries are presented. Use of intercalare insert at seedlings receiving of apple-trees is rather effective technological method raising both efficiency, and productivity of orchards, and also commodity qualities of fruits. However and now questions of influence of intercalare insert on growth and development of a fruit tree is studied not enough, and also questions of perfection of technologies of apple seedling receiving with intercalare insert are demand further research. As a result of cultivation of annual seedlings in a film greenhouse with an intermediate insert dwarfish and semidwarf high winter hardiness stocks of selection allows to reduce sharply terms of their cultivation and to receive in 4-6 times more standard seedlings, than in field conditions. Profit at apple-trees seedlings with an insert of clonal stocks in a hothouse has made 213 thousand roubles at profitability of 210 % in account upon 1 ha of film greenhouses. It is established, that on a complex of studied attributes for the western part of Byelorus the traditional four-year-old know-how apple-trees seedlings with intercalare insert, including seed stock grafting in late summer period with repeated grafting of inserted component in late summer period of next year is the most preferable
