| Abstract:
Varieties of apricots resistant to plum pox virus (PPV) and their resistant hybrids with susceptible varieties of apricots that are donors of fruit quality were grafted in spring onto the variety Vegama, which is susceptible to PPV, had been infected with and shown symptoms of PPV. Growing grafts showing no leaf symptoms were evaluated during the following winter and spring by enzyme immunosorbent assay (ELISA) and immunosorbent electron microscopy (ISEM) for the presence of PPV. This was done on the green bark, leaf and flower tissue of 39 varieties and hybrids of apricot. Varieties Harcot, Veecot, Goldrich, Da Ju Bada, Zhang Gong Juan, Krymskij Amur, Mari de Cenad, and Vestar showed symptoms of PPV already in the year of grafting. PPV was detected by ELISA and ISEM in the next year in the varieties Stark Early Orange, San Castrese, Mai Chua Sin, Harval, Chuang Zhi Hong, Stella and in 21 hybrids of apricot. PPV was not detected by ELISA and ISEM in the varieties Harlayne, Leronda and in 10 hybrids of apricot. | |
