摘要

甜瓜的主要品质参数与蔗糖积累量和可溶性固形物含量有关。了解这些性状的遗传控制是帮助育种者在选择过程中必不可少的。本研究旨在探讨甜瓜蔗糖积累和可溶性固形物含量的遗传特性。采用3个重复的随机区组设计，对AC-16和Vedrantais亲本以及F1、F2、BC1和BC2代进行评价。本研究证实，蔗糖是造成亲本间糖含量遗传变异和环境变异的主要因素。蔗糖含量的遗传涉及具有加性效应的主效基因和具有加性效应的显性基因。可溶性固溶体的遗传涉及一个具有加性和显性效应的主基因，与多基因、加性效应和上位性相关。

Inheritance of soluble solids content and sucrose in melon

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.
