Conteúdo:	This study estimated genetic gains obtained with different selection indices to select superior genotypes for multiple traits in table grape progenies from controlled hybridizations using the REML/BLUP methodology. Seventy-six table grape hybrids (F1) were evaluated for yield, number of clusters, cluster weight, berry length, berry diameter, and berry weight in Juazeiro, Bahia, Brazil, over four to nine growing seasons. Repeatability coefficients ranged from 0.12 to 0.53, with accuracy estimates higher than 79% for all evaluated variables. The factor analysis and genotype-ideotype and multi-trait genotype-ideotype distance indices showed more balanced genetic gains across traits, which were proportional to the gains obtained through direct selection. Multi-trait selection led to selection of nine promising table grape genotypes exhibiting favorable performance for traits related to yield, cluster, and berry physical traits. These genotypes should advance to subsequent evaluation and selection stages for development of new table grape cultivars adapted to the semi-arid conditions of the São Francisco Valley in Brazil
