Heterosis schemes of breed linear crossing of Belarusian black-motley breed of boars with sows of Belarusian great white breed are developed. They allow to increase sows' multiple pregnancy rate at 0,35-0,4 heads, litter weanling weight - at 3,5-4,0 kg. Use of estimation technique of breeds compatibility at natively-linear level allows objectively and quickly spend an estimation and selection of initial parental pairs and combined lines for increase of sows efficiency and receptions of highly pedigree posterity
