Abstract

Apple proliferation disease (ApPL) is economically important in Europe.
In the search for genetically mediated tolerance, the response of 16 apple rootstock clones was investigated.
Container-grown liners were artificially inoculated with ApPL and observed for three and two years, respectively, for symptom expression and disease incidence.
Shoot growth and specific leaf weight were determined.
Response to fire blight was tested by Richter, Aschersleben.
Incidence of woolly apple aphid and burr knots was observed. For twelve clones inoculation efficiency ranged between 10% and 50%. There was no impact of ApPL infection on shoot growth or specific leaf weight.
Therefore, it was not possible to quantify the disease response by means of growth.
Five rootstock clones, AP 4551, Geneva^® (G) 16, M.8, Supporter 2 and G.41 seem promising with regard to tolerance to ApPL since artificial inoculation with the pathogen failed or gave only 10% success.
Considering all the parameters under observation, with special regard to fire blight susceptibility, three clones, AP 4551, G.16 and G.41, are promising and worth further study.
