Inheritance of resistance to Plum pox virus in apricot progeny from crossing of 'Harlayne' x 'Betinka'
Original language description
Inheritance of resistance to Plum pox virus (PPV, Sharka) is studied in 201 apricot hybrids resulting from a controlled pollination between the immune cultivar 'Harlayne' and the resistant cultivar 'Betinka'. Each hybrid was inoculated at the base, with a bud from a plum tree infected with PPV (D and Rec strains), by a chip-budding method. Five symptom observations per year were made on the leaves of the hybrids during four growth periods. Leaves of hybrids were used to confirm the presence or absence of the virus by an enzyme-linked immunosorbent assay (ELISA) method. On the basis of these observations the hybrids were assigned to one of six groups according to evaluation of their response to PPV infection: immune, resistant, medium resistant, tolerant, susceptible, and very susceptible. About 75 % of the F1 hybrids were resistant and 15 % were tolerant. This is probably caused by two dominant loci with epistatic interaction of resistance to PPV.
