Abstract

This review serves as a critical framework for guiding future research into the causes of russeting and the development of effective control strategies to enhance fruit quality. Russeting is a condition characterized by the formation of brown, corky patches on fruit skin which significantly impairs both the quality and market value of apples. This phenomenon arises from a complex interplay of various biotic and abiotic factors. Among the abiotic factors, environmental conditions, such as light, temperature, and relative humidity, as well as nutrient imbalances and the application of agrochemicals are important, whereas biotic factors include the influence of yeasts, fungi, viruses, and bacteria. The susceptibility of apple cultivars to russeting varies with yellow-fleshed varieties generally exhibiting higher incidences compared to red-fleshed ones. While russeting is partly determined by varietal and genetic factors, it can be mitigated through the implementation of effective cultural practices, nutrient management, plant growth regulators, biological agents, and pesticides. Understanding these dynamics provides valuable insights for developing future research strategies aimed at improving fruit quality and production.
