Summary
Monilinia laxa causes important pre- and post-harvest losses in stonefruit. In order to initiate a breeding programme for increased resistance toM. laxa, two screening tests were used. In the “uninjured fruit inoculation” test, 30 mature fruits of each variety were inoculated on their surface by depositing 20 μl of conidial suspension. In the “artificially injured fruit inoculation” test, 10 mature fruits were inoculated on both sides by injecting 20 μl of conidial suspension. Genotypic differences were found in both tests, within the three species studied. Marked differences were observed in the uninjured fruit inoculation test. Differences between genotypes were slighter in the artificially injured fruit inoculation test. Within each species, the rankings of the genotypes according to the two tests were not correlated. Both testing procedures would be usefully applied in a breeding programme to obtain genotypes with combined resistance toMonilinia laxa.
