Intra-Cultivaral Variation in Hard Red Winter Wheat1

  1. E. G. Heyne and
  2. Mohamed Ahmed Siddig2



Selections were made from 31 wheat breeding lines and cultivars that were phenotypically similar to the original. One to 15 lines were compared with the original and with the bulk of all the selected lines. On the average, the original and bulks gave more consistent performances than the individual selections, suggesting that a cultivar in hard red winter wheat need not consist of a single genotype but of several phenotypically similar lines. Fifteen to 85 lines adequately represented the original.
