for the carrot cultivation it is important to understand the adaptation of cultivars according to the local weather conditions and consumer preference. the objective was to evaluate the performance and acceptance, thereby detecting the consumer's preference for different carrot cultivars in organic cropping system. the performance of the cultivars nantes, shin kuroda and danvers flaker was evaluated in the winter season and cultivars shin kuroda, kuronan, brasilia, esplanada and carandaí for cultivation of summer in dois vizinhos, paraná state, brazil. the experimental design was randomized blocks with five replications and four treatments for the winter season and five treatments for the summer season. we analyzed the resistance to leaf blight (alternaria dauci), incidence of green shoulder, total soluble solids, yield and acceptability through sensory analysis of fresh carrots and canned pickles type. on the winter crop, cultivar nantes resulted in higher yield (29.02 t ha-1) and on the summer crop cultivar esplanada productivity was higher (32.0 t ha-1) without statistical difference. the cv. esplanada was more resistant to leaf blight and presented the lowest percentage (5.6%) of green shoulder. for sensory analysis, the cvs presented good acceptability from the participating consumers.
