Description:	The development and evaluation of new cultivars of seedless grapes (Vitis spp.) with good yield and adapted to different edaphoclimatic conditions are essential to increase the competitiveness of the productive system. The present work had the objective to characterize the phenology and the yield of the new hybrid seedless grape ?BRS Melodia?, grown in an annual double cropping system in a subtropical region. The evaluations were carried out during the 2013 summer cropping period and the 2014 off-season cropping period in a commercial area located in Marialva, PR, Brazil. The ?BRS Melodia? scions were grafted onto ?IAC 766 Campinas? rootstocks, trained in an overhead trellis system spaced at 2.5 × 2.5 m. In both seasons, the duration in days of the main phenological phases of the vines, as well as their thermal demand and their physicochemical and productive characteristics were evaluated. The ?BRS Melodia? seedless grapevines presented a cycle of 138 days and yield of 23.85 tons.ha−1 in the summer season, and 121 days and yield of 19.4 tons.ha−1 in the off-season crop. The soluble solids, titratable acidity, and maturation index were 15.1 ◦Brix, 0.5% tartaric acid and 28.5, respectively, in the summer season and 15.4 ◦Brix, 0.6% tartaric acid and 25.6 in the off-season crop, indicating a possibility of cultivate this new hybrid seedless grape under an annual double cropping system in subtropical conditions.
