Abstract
ABSTRACT The main quality parameters of melon are related to sucrose accumulation and soluble solids content. Understanding the genetic control of these traits is essential to help breeders in the selection process. The aim of this study was to evaluate the inheritance of sucrose accumulation and soluble solids content in melon. A randomized block design with three replicates was used to evaluate AC-16 and Vedrantais parents, and F1, F2, BC1 and BC2 generations. We verified that sucrose is the main factor which is related to genetic and environmental variability observed in sugar content between parents. The inheritance of sucrose content involves a major effect gene with additive and dominance effects associated with polygenes with additive effects. The inheritance of soluble solids involves a major gene with additive and dominance effects associated with polygenes, with additive effects, and the presence of epistasis.
