果实成熟及品质调控遗传研究进展

Genetic Research Progress of Fruit Ripening and Quality Control

果实的成熟涉及许多生物化学变化过程,主要包括香气、糖的产生以及果实软化等,这与果实在成熟过程中所发生的一系列代谢路径密不可分。因此,研究并了解果实成熟过程及品质调控遗传学机理,对于果实品质改良具有重大意义。本综述将结合近年来国内外果实成熟及品质改良遗传研究现状,对果实成熟变化遗传分析研究中的代谢路径、果实品质改良遗传规律、品质QTL等进行综述,旨在为果树品质育种研究提供技术参考。

Fruit ripening involves many biochemical processes, mainly including aroma, sugar production, fruit softening and so on, which is closely related with a series of metabolic pathways in the process of fruit ripening. Therefore, studying and understanding the fruit ripening process and genetic mechanism of quality control is of great importance to the improvement of fruit quality. Combined with the genetic studies of fruit ripening and quality improvement at home and abroad in recent years, this study summarized metabolic pathways in genetic analysis of fruit ripening, genetic law of fruit quality improvement, and quality QTL, aiming to provide technical reference for quality breeding of fruit plants.
