Performance of Geneva & REG; series apple rootstocks grafted with 'Gala Select' in four different replanting soil at Southern Brazil

The objective of this study was to evaluate the agronomic performance of the Geneva & REG; series apple rootstocks G.202, G.213, G.210 and G.814. The rootstock G.202 and G.213 proved to be the less vigorous, being considered dwarfs. For replanting soil, 'G.210' was considered an efficient alternative. The 'G.213' was the most efficient, in a general point of view, demonstrating that it does not change its yield efficiency and stability characteristics, even under replanting conditions. All rootstocks reached the goal of 120 accumulated tons.ha-1 in Caxias do Sul-RS, highlighting the faster financial return to the growers. 'G.213' has higher soluble solids content, indicating the possibility of an earlier harvesting. It is concluded that the G.210 and G. 213 rootstocks are good options for the areas evaluated, under replanting conditions, mainly G.213 for more dense systems and G.210 for areas under extreme replanting conditions.
