果皮颜色是葡萄的一个重要品质性状，是葡萄育种中的一个重要选择指标。使葡萄果皮呈色的主要色素物质是花色苷。myb类调节基因对花色苷的生物合成以及葡萄果皮着色起着至关重要的作用。不同的myb类调节基因的基因型及其单倍型决定了极大多数葡萄品种的果皮色泽。本项目拟通过对大量重要的欧亚种和欧美杂种葡萄调控着色的myb类调节基因位点的类型，研究调控葡萄果皮着色myb基因位点单倍型与葡萄果皮着色之间的关系，从而更好的揭示葡萄果皮着色机理以及为葡萄果实色泽分子设计育种提供重要理论依据。

The skin color is one of the most important grape berry traits, which is always one of the important selection indexs in grape bredding. The skin color of grape berry is mainly determined by anthocyanins. Myb genes play important roles in anthocyanin biosynthesis and in the coloring of grape skin. In this project，we will analyze the myb-related regulatory genes'loci in a plenty of V.vinifera and V.×labruscana varieties,the haplotypes these genes compose, in order to understand the relationships between the haplotypes of the related myb genes and coloring of grape skin of the different varieties. The result can also provide some important theoretical basis for our better understanding of the coloring mechanism of the grape berry and for molecular design breeding of color or green color grape berry cultivars.
