The research was carried out in the period 2016-2018, in an experimental plantation established in 2015, with the Pinova variety in several graft combinations, directly on the B9, M9, MM 106 and Pi 80 rootstocks, and with B9 as intermediary on the A2 and MM106 rootstocks. The soil was maintained worked along the row for most variants, for 2 variants with grafting intermediary the soil was kept grassed, and for other 2 variants the intermediary was buried at planting. The rootstock influenced fruit production and fruit quality differently. The highest average production in the first years of fructification, of over 26 t/ha, were obtained for the rootstocks B9, M9 and combinations with intermediary of B9/MM106. The largest fruit were obtained from trees grafted with intermediary on A2 and worked soil, over 169 g and about 78 mm in diameter. A higher amount of soluble dry matter was recorded for the fruit obtained from grafted trees from variants V2, V5 and V8, while higher carbohydrate content was recorded for the variants V2, V8 and V1. The best firmness had the fruit of the V8 variant, while higher content in anthocyanins had the fruit of the V8 and V7 variants.
