Phosphorus is a vital nonrenewable natural resource that is essential for plant and animal growth. Grass swards and buffer strips can be used to reduce P losses that occur by soil erosion, surface runoff, or leaching. The objective of this study was to conduct one cycle of divergent selection for P concentration in reed canarygrass (Phalaris arundinacea L.) and to evaluate the effects of selection on P concentration, forage yield, and P uptake (the product of P concentration and forage yield). Divergent selections and original populations were evaluated in sward plots, harvested three times per year for 2 yr at three locations. Selection responses indicated that P concentration is a heritable trait in reed canarygrass; that genetic gains were highly repeatable across harvests, locations, and years; and that there is a negative genetic correlation between P concentration and sward-plot forage yield. Future selection efforts must be based on genotypic selection methods, in which half-sib families are evaluated for forage yield, P concentration, and P uptake in sward plots.
