European stone fruit yellows (ESFY) is the most destructive phytoplasmas disease of apricot and Japanese plum in Europe. All conventional preventive defence strategies have been ineffective in the past, however it has been demonstrated that individual plants can recover from the disease, behaving as completely tolerant to ESFY. The status of tolerance seems transmissible by grafting, so investigations about the possibility to transmit this status from visually recovered apricot to Japanese plums in the field, under high ESFY-infection pressure were carried out.
