Evaluation of resistance of apricot cultivars to a Spanish isolate of plum pox potyvirus (PPV)

The resistance of 12 apricot cultivars to the Dideron type Spanish isolate RB3.30 of plum pox potyvirus was evaluated in controlled conditions in an insect-proof greenhouse. The results of the evaluation demonstrated the resistance of the cultivars ‘Stella’, ‘Stark Early Orange’, ‘Goldrich’, ‘Harcot’, ‘NJA2’, ‘Pandora’ and ‘Avilara’ to the isolate, and the susceptibility of the cultivars ‘A1453’, ‘Bulida’,‘Currot’, ‘Real Fino’ and ‘Canino’
