| Abstract:
Apple cultivars with scab resistance of monogenic or polygenic control have been assessed for fruit quality since 1972. So far, the cultivars with monogenic control and complete resistance have not approached the same level of eating quality as the cultivars with polygenic control and partial resistance. New cultivars with complete resistance will be included in the cultivar testing program, and the level of eating quality will hopefully be improved. At the Dept of Horticulture, Section Pomology (formerly Dept of Pomology), the breeding for scab resistance began in 1981 with crosses including Prima. In later years several other scab resistant parent cultivars have also been used, for example A 347–6 from East Malling, BM 41497 from Balsgaard, NY 18491 and NY 55140–9 from Geneva, and Priam, Florina and x3183 from Angers. The scab resistant offspring were flowering for the first time in 1988, and the evaluation of fruit properties will start in 1989. | |
