Grapevine cultivation has been gaining commercial popularity in many parts of the world due to the high yield and versatility of this horticultural crop.A recent survey from the International Organization of Vine and Wine (OIV) estimated that the global area under vine cultivation in 2018 was about 7.4 million hectares and that the world production of grapes was about 77.8 million tons in total (OIV, 2019).The majority of the global grape yield is used for producing wines, fresh fruit, and raisins, bringing in annual revenue of billions of US dollars (Alston and Sambucci, 2019).In addition to its economic value, the grapevine is also a useful model for the study of the genetic basis of clonality, fruit development, sex determination, grafting, evolution, and domestication (This et al., 2006).Furthermore, for many countries in the world traditional viniculture and viticulture are important emblems of cultural identity.All these factors have made grapevine one of the most heavily invested plants in horticultural research.
