“…The superiority of the temporary environmental variance (V te ) in relation to the permanent phenotypic variance estimated between plants (V pp ) (Table 2) indicate that these characteristics are highly influenced by environmental conditions. Results similar to these were reported by Carvalho et al (2023) for yield, number of bunches, bunch traits, soluble solids content, titratable acidity and ratio; Sanchéz et al (2017) for fruit production; and Sales et al (2019) for all the variables evaluated by them (yield, bunch weight, soluble solids content, and ratio), with the exception of the number of bunches, in which the V pp values were greater than the V te values. In contrast, Leão et al (2018) detected higher V pp…”

The absence of seeds has been one of the most valued traits in grapes (Vitis spp.) for fresh consumption. However, the simultaneous selection of superior genotypes for multiple traits is complex. The objective of this study was to select genotypes of superior seedless table grapes in semiarid regions of Brazil. Multiple traits were considered by using the factor analysis and genotype–ideotype best linear unbiased prediction (FAI‐BLUP) selection index. A total of 110 grape progenies from 24 crosses were evaluated for traits of agronomic interest. Each hybrid was represented by a single vine plant, without experimental design or repetition. The mixed‐model methodology was used to predict the breeding values. The FAI‐BLUP index was used to select superior genotypes based on factor analysis and the genotype–ideotype distance. Four factors explained the 11 characteristics studied, with a variability of 81.84%. Desirable gains were observed for 10 of the 11 traits evaluated. The FAI‐BLUP index allowed the selection of superior seedless table grape hybrids, which can be used in the genetic improvement of grapevines. In conclusion, we report the selection of seedless table grape hybrids for our study to advance in the table grape breeding program in Brazilian semiarid regions.
