Technical Abstract: At harvest maturity of pome fruit it is a critical component of orchard management decisions, especially with regard to postharvest outcomes. This is because the risk for many postharvest physiological disorders changes as fruit maturity advances. Therefore, highly accurate maturity indices are important for producers to predict postharvest performance with regard to maintenance of fruit quality. Towards expanding the postharvest toolbox, we aim to discover genetic factors that influence postharvest fruit quality by exploring how the production environment, cultivar genetics, and fruit maturity interact to produce outcomes after extended storage. Using functional genomics combined with classic horticultural research approaches we studied a tractable physiological postharvest disorder, Superficial Scald in ‘Granny Smith.’ Risk for this disorder is maturity dependent, and there are many ways to modulate disorder risk – we therefore explore these contrasts to learn about the genetic factors that influence Superficial Scald development.
