The results of a comparative study of parameters of accumulation of phenolic compounds in fruits of early-, moderate- and late-maturing modelling species of highbush blueberry in austral, central and boreal agroclimatic areas of Belarus in field experiments with the identical 8-alternative scheme of addition N60,P60,K60 are given. It has been found that on the background of variety differences of plants response on the change of geographical position of the study area, with advance into boreal direction accumulation of anthocyan pigments in fruits increased by 17-21%, mainly at the expense of essentially anthocyanins, tanning agents by 19-37% and lignines by 26-69%, at the absence of interregional differences in the contents of catechins, and in early- and moderate-maturing species also flavonol, for which its decrease by 12% only in late-maturing species is shown. Thus the most significant variety differences in accumulation in fruits of blueberry of anthocyan pigments, bioflavonoids as a whole and tanning agents (in limens of 6-59%) is fixed in the central area of study, catechnis (up to 10%) - ib boreal, flavonoid (up to 7-9%) - in austral
