Conteúdo: | The Grape Germplasm Bank of Embrapa Semiarid is the only one present in the northeast of Brazil, in a semi-arid tropical climate, and represents a strategic resource for the sustainability of tropical viticulture. The first vines were planted in 1965, at the Mandacaru Experimental Station in Juazeiro, BA (9°24?S 40°26?W, 365.5 m altitude). The current collection is composed of 268 genotypes, with 54% table grapes and raisin cultivars, 34% grapes for wine and juice production, 5.2% rootstocks, 1.9% wild American species and 4.8% of unknown origin. In addition, 62.6% of the genotypes belong to the species Vitis vinifera L., interspecific hybrids being the second group, with 27.2% of genotypes. The Grape Germplasm Bank of Embrapa Semiarid has been used as the source of germplasm for grape breeding programs aimed at developing new seedless table-grape cultivars adapted to the semiarid tropical environment of northeast Brazil, in addition to being used in other studies such as genetic divergence, screening for disease-resistance genotypes, and characterization of bioactive compounds. The results from these various studies are important to strengthen and sustain the Brazilian viticulture industry.
