Genome-wide association study of berry-related traits in grape [Vitis vinifera L.] based on genotyping-by-sequencing markers

Abstract

Grapes: The genetic basis of fruit traits Genetic analysis of 179 types of vine has revealed regions of the genome and associated genes and proteins that control many of the key traits in the grapes. These traits are crucial for determining fruit quality and yield, in addition to conferring flavors that are highly valued by consumers and wine makers. Researchers in China, led by Da-Long Guo at Henan University of Science and Technology, used DNA sequencing to analyze genetic markers in a mixture of ancient, traditionally cultivated and modern grape varieties. The analysis identified specific regions of the genome linked to grape fruit development, weight, texture, skin color and flavor. The molecular basis of the effects of the identified genetic regions were also explored. The findings will help generate new varieties of grapes for the food and wine industries.
