Dendrogram of 26 inbred lines that have the best favourable alleles of crtRB1-5′TE and crtRB-3′TE marker. The pedigrees refer to the sources from which the inbred lines were derived. The numbers after the pedigrees are inbred line entry numbers. Numbers in parenthesis are mean β-carotene concentration in μg-1 DW. Entry 99 is the line used in  for developing segregating populations. Twenty of the inbred lines contained the favourable alleles of both markers except for those marked with *.
