The article presents the material of forecasting for grape yield of next year and establishing the optimal loading if cutting of bushes. The material includes 14 varieties of grapes, 11 of them are technical and 3 are table ones. For each year of stable high yield of grapes, it is necessary to pre-set the optimum length of fruit cutting of shoots and optimum load on the bush healthy eyes. To do this for each variety on the eve of trimming bushes we perform optimum productivity analysis of wintering buds of fruit along the length of shoots, i.e. we implement forecasting of grape yield for next year. We have a plan of forecasting for yields of vineyards by microscopy of wintering buds on one-year shoots of fruit ripened grapes in order to establish the potential of embryonic establishment of inflorescences in the central holes of buds. Based on the analysis of buds, the indices were calculated for wintering fruiting buds and their degree of damage during the growing season. It was revealed, that the majority of grape varieties under study shows high tab embryonic inflorescences in central buds in overwintering buds for next year yield. Higher rates at a rate of fruiting buds were wintering in the varieties: Moldova (section 27). - 1.66; Bianca (section 6). - 1.83; Kunlean (section 15). - 1.71; Merlot (section 14). - 1.64; Saperavi (section 56). - 1.76. The lowest rates of fructification - the varieties Muscat Hamburg (section 21) and Augustine (section 11) and were respectively 1.20 and 1.24. As a planned productivity, we offered the optimal loading model of cutting bushes buds. As a result of productivity analyzes of buds along the length of the fruit shoots in 2016 we recommended to carry out pruning of fruit annual shoots 3-4 buds of the form of AZOS-1 and the form of cordon - 5-6 buds
