This research Project was carried out in the Santa Teresa Experimental Field at the Universidad Nacional Agraria La Molina, Lima, Peru, from September 6 to December 27, 2006. The main objective was to evaluate 16 selected genotypes of the cv. Centenary bean (Phaseolus vulgaris L) under two seeding densities for their quality and yields under the conditions of the central coast. Yields and other agronomic characteristics related to seeding densities were studied in two experiments, Density D1 (0.25m) and Density D2 (0.20m). The experimental design used was the “Randomized Complete Block Design” with 16 treatments and 3 replications yielding a total of 48 experimental units for D1 (150,000 pl/ha) and D2 (187,500 pl/ha), to test the selected genotypes of the Canary cv. Centenary bean by means of the variance analysis of each experiment. Then a combined analysis of both experiments was made. Highly significant differences were detected in the combined variance analysis for the following variables: length of pods, number of grains per pod, and grain yield (kg/ha). Finally, there were no statistically significant differences for the interaction (DDxGG) except in the yield/ha parameter with a statistical significance of 0.05. With respect to the average density of the plants D1 (150,000 pl/ha) and D2 (187,500 pl/ha), there were highly significant differences in the following variables: plant height, number of pods per plant, number of grains per pod and yield per hectare; significant differences in the pod length DxG interaction for the combined analysis o variance, and no statistically significant difference for the following variables: plant height and dry weight of 100 seeds. he maximum value for average yield of the Canary cv. Centenary bean (2307.77 kg/ha) was achieved with the T3 treatment. The results of the combined ANVA show that the treatments that achieved the highest average yields (D1 and D2) were T3 (with 2037.77 kg/ha), T13 (2201.00 kg/ha) and T8 (2162.27 kg/ha) respectively. These values were optimal for the area and quality of commercial grain and were much higher than the national average. It can be concluded that the tested genotypes T3 (2307.76kg/ha), T13 (2201.00 kg/ha) and T8 (2162.27kg/ha) in D1 and D2 are promising for their suitable agronomic characteristics, good physical quality of grain (color, brilliance, shape and size) and acceptable yields. Finally, in the economic analysis, the highest profit index was achieved by the T3 treatment (with 2,925.12 kg/ha) for D2 (187,500 pl/ha) with 118.06% due to higher plant density for 0.20m
