| The performance of 14 old apple varieties planted in three experimental plots was evaluated over four or five seasons. The yield and fruit size were recorded on conventionally grown trees. The level of disease and pests on trees and fruits was estimated in an organically grown unsprayed plot, and the eating quality was evaluated in an unsprayed experimental plot. Large differences in yield and fruit size were found between varieties. It was demonstrated that Holsteiner Cox was the only variety that combined high yield, good fruit size and good eating quality with an acceptably low susceptibility to disease. Most varieties had poor eating quality. ‘Holsteiner Cox’ had a medium susceptibility to canker and powdery mildew, while susceptibility to apple scab... |

| Twentyfive apple varieties were evaluated for Apple scab (Venturia inaqualis), Nectria canker (Nectria galligena) and Powdery mildew (Podosphaera leucotricha) for 4 to 7 years. The trees were grown unsprayed. The weather conditions at the experimental orchard normally results in high infections of apple scab and low infections of powdery mildew. Infections of Apple scab is often seen also in scab resistant varieties. Williams Pride, Katinka and Katrina (scabresistant varieties) were the only varieties not showing scab in the experimental period. The two scabresistant varieties Angold and Produkta (varieties having a poor fruit quality) was unsusceptible to Nectria canker. The reference variety Elstar/Elshof was in all plantings among the most... |
