Commercial pear varieties worldwide are grafted on rootstocks of Pyrus and Cydonia. Quinces rootstocks have been widely used due to two beneficial characteristics provided to the scion tree as size reduction and yield precocity. However, most pear cultivars exhibit graft incompatibility when grafted on quince rootstocks due to physiologic and biochemical factors. Aiming to compare compatibility levels, 41 five-year-old scion/rootstocks combinations trained in medium/high density (2000 trees/ha)
