A rootstock trial of peach cv. Catherina has been performed over a range of almond x peach hybrids: Adafuel, Adarcias and INRA GF 677. Harvest time, growth, yield, fruits size and productivity characteristics were recorded over 10 years. While there are not productivity differences in Catherina grafted on different rootstocks the tenth year, Catherina grafted on Adarcias showed the least vigour.Trabajo financiado sucesivamente por CAICYT, 79/3119 y 84/0180; CSIC, 61142/02; CICYT, AGR 88/0074 y AGR 91/0434, y por CONAI-DGA.Peer reviewed
