Susceptibility of fruit from diverse apple and crabapple germplasm to attack from apple maggot (Diptera: Tephritidae).
Apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), is a pest of major concern to apple, Malus x domestica (Borkh.) production in eastern North America. Host plant resistance to apple maggot among apple germplasm has been previously evaluated among a small number of exotic Malus accessions and domestic hybrid selections. However, a large number of exotic accessions housed in USDA...
متن کاملSusceptibility of fruit from diverse apple and crabapple germplasm to attack by plum curculio (Coleoptera: Curculionidae).
Plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), is an important apple, Malus domestica Borkh., pest that significantly hinders sustainable apple production in eastern North America. The potential for host plant resistance to plum curculio among apple germplasm has never been rigorously evaluated. Thus, studies were conducted to assess the susceptibility of a number o...
متن کاملAn Assessment of the Durability and Susceptibility of Scab Resistance in Apple Cultivars
Durable resistance to scab (Venturia inaequalis) of newly introduced cultivars is needed to achieve a considerable reduction of pesticide use. However, the assessment in the field on the level and durability of scab resistance is time and space consuming. A proper and fast indoor test should be a convenient tool to discard cultivars with a limited level of resistance at an early stage. As a res...
متن کاملApple Scab Management Options for High-Inoculum Orchards
Apple scab emerged as an expensive problem in apple orchards throughout the Northeastern United States in 2009. Experienced growers who had managed scab effectively for many years found themselves spray ing throughout summer to control scab that kept appearing on new leaves. Th e effort required to protect fruit from scab during summer increased production costs and represents a “loss” to apple...
متن کاملMetabolic and gene expression analysis of apple (Malus × domestica) carotenogenesis
Carotenoid accumulation confers distinct colouration to plant tissues, with effects on plant response to light and as well as health benefits for consumers of plant products. The carotenoid pathway is controlled by flux of metabolites, rate-limiting enzyme steps, feed-back inhibition, and the strength of sink organelles, the plastids, in the cell. In apple (Malus × domestica Borkh), fruit carot...
