Experiments were conducted to evaluate the screening honeycomb design of Fasoulas (1973, 1977) as a tool in the evaluation of yield potential in early generations. The design failed to improve correlations of yields of spaced plants in the honeycomb with yields of randomized complete blocks with yields were compared. Yields of individual plants modified as a percentage of surrounding hexagon were generally slightly better than yields modified as a percentage of surrounding control triangle, but neither modification justified the effort involved. Correlations were so low that plants spaced 0.70 m. or above cannot be recommended in any evaluation of beans. Correlations between mutually exclusive sets of 2 randomized complete blocks ranged from 0.72** to 0,93**, suggesting that 2 randomized complete blocks were a more reliable measure of yield potential than 8 individual spaced plants in the honeycomb design.
