Within 2005-2010 years of the research the influence of crown formation methods of pear (Pyrus L.) trees on growth and fruiting of different varieties on the seed rootstock (varieties mixture) was studied in the orchard of 2005 planting year in the conditions of the Republic of Belarus. As a result, the variety reaction on different methods of pear tree crown formation was revealed. The method of crown formation by sprouts cutting and shortening reduced tress growth vigour of the variety 'Kudesnitsa' and hybrid 90-39/80. At trees of the variety 'Prosto Mariya' the growth vigour was lower at sprouts cutting crown formation. At all studied varieties on the average the yield was higher at crown formation by sprouts cutting. On the fifth year after planting at such a formation system the variety 'Prosto Mariya' produced 15.1 tons per hectare and the variety 'Kudesnitsa' produced 18.0 tons per hectare that ensured for higher profitability level and quicker recoupment.
