To recognize carrot cultivars with high potential of cultivation, the present study was carried out to determine the productivity, adaptability and phenotypic stability of nine open-pollinated carrot cultivars (Alvorada, Tropical, Brasilia [1], Nova Brasilia, Carandai, Brasilia [2], Brazlandia, HT-2000 and Brasilia-RL). The research was done in Sao Jose do Rio Pardo, Sao Paulo State, Brazil, during October and November of 2002 and January and March of 2003, under single- and double-row spacing. A total of eight cultivation environments (OCT-S; OCT-D; NOV-S; NOV-D; JAN-S; JAN-D; MAR-S and MAR-D) were studied using a complete randomized blocks design with three replications. The data were submitted to individual and joint analysis variance and to analysis of adaptability and stability. The cultivars Alvorada, Nova Brasilia and Brazlandia presented favorable potential for cultivation in the studied seasons and spacings.
