The objective of this study was to characterize the phenology and determine harvest points snap bean varieties related degree-day accumulation. experiments were conducted in Teaching Garden Federal University Ceará, evaluating five genotypes. A randomized block design with three replications used for 1 2, respectively. Each experimental unit consisted a 9.6 m seedbed. In first experiment, spacing adopted 0.1 x 0.4 (24 plants per plot). For second 0.3 (32 Phenological characterization carried out, estimating thermal requirement pod growth curve. evaluated genotypes presented requirements ranging between 1,282 2,111 °C day. Habichuela genotype shorter cycle length, lower accumulation higher initial compared others. It is recommended Feijão Vagem do Panamá (FVP), De Metro 10th 15th day after fruiting.
