Abstract: Two green bean (Phaseolus vulgaris L.) germplasm evaluation trials were conducted during the spring of 1994. Cultivars evaluated in the first trial were 'Blue Lake 274', 'Contender', 'Green Crop', 'Top Crop' and 'Tenderpod'. Stem diameter of plants did not differ significantly among cultivars. 'Tenderpod' plants had a mean height of 33.7 cm and were significantly taller than 'Contender' plants (25.5 cm). The widest pods were produced by 'Top Crop' (0.83 cm), significantly wider than pods from the other cultivars. The longest pods were produced by 'Green Crop' (14.4 cm), and the mean pod weight was significantly superior to 'Tenderpod'. 'Green Crop' was also significantly superior in total yield (7.37 t/ha) to 'Top Crop' and 'Green Pod' with yields of 4.46 and 4.27 t/ha, respectively. Cultivars evaluated in the second trial were 'Contender', 'Derby', 'Dandy', 'Honey Gold', 'Kentucky Wonder' and 'McHarvest'. Plant height and stem diameter were similar for all cultivars. 'Contender' produced pods that were significantly longer (10.9 cm) than those obtained from all other cultivars. Pods from 'Contender' and 'McHarvest' had the highest mean weight (2.7 g), significantly heavier than 'Honey Gotd' (2.0 g) and 'Derby' (1.7 g). 'Dandy', 'McHarvest' and 'Contender' produced the largest quantity of pods. The highest yields were produced by 'Contender', McHarvest', and 'Dandy' with 2.3,2,3 and 2.0 t/ha, respectively.
