Contribution to testing the resistance of apple genotypes to witches' broom

Archiv fur Phytopathologie und Pflanzenschutz 23(3): 199-210

Contribution to testing the resistance of apple genotypes to witches' broom

Two mycoplasma isolates were tested on a number of genotypes using 3 methods of inoculation. Differences between isolates in symptom development were observed on susceptible varieties but not on tolerant or resistant ones. Grafting the material to be tested onto infected young trees of the Undine was the best inoculation method. No symptoms were observed on most of the breeding clones tested, on Lord Lambourne or on Malus theifera and M.
