Grapevine is a highly valuable crop worldwide, both from cultural as well as commercial point of view.One major advantage this crop has is that it is well adapted to scarce water conditions.Grapes are also a valuable source of health-promoting compounds such as polyphenols.The main object of grapevine breeding is to develop varieties of high quality, that are resistant to pathogens and at the same time well adapted to a changing environment.Since the beginning of the XXI century, there has been a concerted effort by the international scientific community to develop genomic tools and resources for grapevine culminating in its complete genome sequence.These efforts and their usefulness for grapevine breeding or viticulture improvement are reviewed and discussed in this book by globally reputed scientists in the field.
