The adaptability and phenotypic stability of ten carrot genotypes, nine of open polinization [Alvorada (FELTRIN); Tropical (ISLA); Brasilia (ISLA); Nova Brasilia (ISLA); Carandai (SVS); Brasilia (SVS); Brazlandia (HORTEC); HT-2000 (HORTEC), and Brasilia-RL (SAKATA)] and the hybrid AF-845 (SAKATA), were evaluated under different sowing dates and places. In January and March in Sao Jose do Rio Pardo, January and February in Ponta Grossa and in the first and last week of February in Sao Gotardo and Carandai MG, totalizing eight experiments (SJRP-JAN; SJRP-MAR; PG-JAN; PG-FEV; SG-FEV'; SG-FEV''; C-FEV', and C-FEV''), in complete randomized blocks with four replications. The data were submitted to individual and joined analysis ANOVA and also to the analysis of adaptability and stability. Of the eight environments evaluated, only C-FEV'', PG-JAN and SG-FEV'' were considered favorable to the sowing of carrots, specially the C-FEV". Among genotypes, in the greater number of environments, 'Brazlandia' stood out in total production and commercial roots. In the adaptability analysis, 'Brazlandia' and 'Brasilia-RL' presented a more than proportional behavior, under environment improvement, being indicated for sowing in favorable environments. The hybrid AF-845 showed little response to environmental variations, not being indicated for the studied environments. In general, the genotypes presented a stable behavior in the tested environments.
