    Crop simulation models help in the development of production strategies for future crops and in making tactical decisions during the life cycle of the crop. It is necessary, however, to collect field data to validate the model for a specific production location. In December 2003 and January 2004, two bean (Phaseolus vulgaris L.) populations were planted at the Isabela Substation of the Agricultural Experiment Station of the University of Puerto Rico to validate the CROPGRO model. One hundred and eighteen F8 lines from the ICA Pijao x Montcalm cross and seventy six F10 lines from the Jamapa x Calima cross were evaluated. Randomized complete blocks designs with four replication for the ICA Pijao x Montcalm population and three replication for the Jamapa x Calima population were employed. The phenological and agronomic characteristics were determined and the yield components were estimated. The genetic coefficients were calculated using phenology stages to validate the crop simulation model CROPGRO in Puerto Rico. Temperature, rainfall and soil data were also collected to validate the model in the northwest region of Puerto Rico. Significant differences were observed among lines for all variables evaluated in the experiment. The narrow sense heritability estimates were intermediate for all yield components, except for individual seed weight and number of seeds per pod, which were high. Indeterminate lines had mean seed yields that ranged from 874 kg/ha to 3395 kg/ha. The mean for indeterminate lines was 1903 kg/ha. Determinate lines had maximum and minimum mean seed yields of 1325 kg/ha and 3280 kg/ha, respectively. The mean for the determinate lines was 2174 kg/ha. The lines from Jamapa x Calima cross had mean seed yields ranging from 168 kg/ha to 2047 kg/ha. The mean seed yield of this population was 890 kg/ha.
