Abstract
It is often observed in dry beans ( Phaseolus vulgaris L.) that the number of pods per plant is the most sensitive yield component under high planting densities. Our objectives in this study were to determine the components of pod formation that are most sensitive to density and to examine the relationships among the components. Seven varieties were grown at effective densities of 17, 21, 34, and 63 plants/m 2 and analyzed at maturity for branching, number of racemes, pods, and nodes. Pods per plant were partitioned into pods per raceme (P), racemes per node (R), nodes per branch (N) and branches per plant (B). Only R and B were significantly reduced by higher planting density. Although both these components are positively correlated with pods per plant, they are negatively correlated with each other. We conclude that a bean ideotype for temperate zone monoculture should have a high number of nodes per branch and three to five branches per plant.
