Abstract
Hop progenies from the crosses between hop cv. Magnum, used as a source of high alpha acid content but showing sensitivity to hop powdery mildew, and four male plants partially resistant to this disease, were studied. The resistance to powdery mildew was assessed under natural infection pressure in two stages. The first stage included all plants from the studied progenies and it based on the estimation of disease symptoms on leaves and cones at the stage of technological maturity. The second stage only covered the plants that had been found healthy during the field estimation. A random sample of 250 cones from each plant was assessed for the presence of disease symptoms. The percentage of diseased cones and infection severity were determined. Differences between the studied progenies in the infection level were observed. The lowest percentage of infected plants was recorded for the progenies of the wild male hop found in Bieszczady. No plants fully resistant to hop powdery mildew were found in the progenies, although some of them expressed a high level of partial resistance to this disease. The percentage of plants with partial resistance to hop powdery mildew ranged from 12.8 to 21.1, depending on the progeny. Powdery mildew symptoms were more frequently observed on hop cones than on leaves.
