QTL mapping and genome-wide association study reveal two novel loci associated with green flesh color in cucumber.

ABSTRACT:

Background

Green flesh color, resulting from the accumulation of chlorophyll, is one of the most important commercial traits for the fruits. The genetic network regulating green flesh formation has been studied in tomato, melon and watermelon. However, little is known about the inheritance and molecular basis of green flesh in cucumber. This study sought to determine the main genomic regions associated with green flesh. Three F₂ and two BC₁ populations derived from the 9110Gt (cultivated cucumber, green flesh color) and PI183967 (wild cucumber, white flesh color) were used for the green flesh genetic analysis. Two F₂ populations of them were further employed to do the map construction and quantitative trait loci (QTL) study. Also, a core cucumber ge
