Abstract

Blossom blight caused by Monilia laxa (Ehr.) is the most important fungal disease in Hungarian apricot orchards. The cultivars traditionally grown in the country are susceptible to Monilia laxa (Ehr.) to various extents. In this study the shoots of one tree each of the varieties Zard and Korai Zamatos and 48 hybrids from their cross were artificially infected in vivo with Monilia laxa (Ehr.). The results indicated that when artificial infections are made to evaluate pathogen resistance, this should be carried out on one-year-old shoots, since this is the natural infection point of Monilia . It also appears that, due to the great variability in the size of destroyed tissues, the microscopic analysis of the infections could provide a more reliable evaluation of progeny resistance than comparing the sizes of destroyed shoot areas.
