The objective of this research was to test for the existence of a xenia effect on seed P uptake in maize. Fifteen maize inbreds were crossed onto two hybrids, B73 x Mo17 and Oh43 x W64A, over three years. Seed weight and P concentration were measured and used to calculate seed P uptake. No xenia effect was found for P concentration or for P uptake. A xenia effect was found for seed weight. Although a difference for seed weight was found, it is concluded that open pollinated maize populations can be used for studies measuring seed P accumulation.Collection: CIMMYT Publications Collection
