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.  aGermplasm  aGrapes  aMelhoramento Genético Vegetal  aRecurso Genético  aUva  aVitis Vinifera  aViticultura tropical  tActa Horticulturaegn. 1248, p. 81-86, 2019.
