  • a One orange/yellow endosperm line, Ames 24575, and one white endosperm line, PI595547, were excluded because of missing data.

  • b 0.001 < P < 0.01.

  • c Two orange/yellow endosperm lines, Y-4 and PI595559, were excluded from analysis because of excessive missing data.

  • π, nucleotide diversity/site; θw, Watterson's estimator (calculated using the no-recombination assumption); NS, not significant (P > 0.10). Estimates are based on all nucleotide sites. Dashes indicate that the measure of diversity for that particular set of lines cannot be calculated.
