  • Description: 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. RESUMO Os principais parâmetros de qualidade do fruto de melão relacionam-se com o acúmulo de sacarose e o teor de sólidos solúveis. O conhecimento do controle genético desses caracteres é fundamental para auxiliar o melhorista no processo seletivo. Objetivou-se com este trabalho estudar a herança do acúmulo de sacarose e do teor de sólidos solúveis em melão. Utilizou-se o delineamento em blocos casualizados com três repetições para avaliar os genitores AC-16 e Vedrantais, e as gerações F1, F2, RC1 e RC2. Verificou-se que a sacarose é o principal fator que confere a variabilidade genética e ambiental observada no teor de açúcar entre os genitores. A herança do teor de sacarose envolve um gene de efeito maior com efeitos aditivos e de dominância associado aos poligenes com efeitos aditivos. A herança de sólidos solúveis envolve um gene maior com efeitos aditivos e de dominância associado aos poligenes com efeitos aditivos e a presença de epistasia.
