Origin of seed by region includes communities closest to the common garden (see Table 1). ANOVAs for bifactorial experiment (origin of seed × color of variety); color of grain was nonsignificant in all cases (data not reported). Mean differences by Tukey's test (letters beside yields) are reported by common garden.
