Starches, of contrasted pasting properties from two bread wheat cultivars, were fractionated on the basis of granule size. Differences in starch hot‐pasting characteristics were observed mainly between large A‐granule fractions (diameter about 23 μm) of the two starches. Less pasting differences were seen between B‐granules (diameter < 10 μm) of the two starches. Examination of immature starches suggested that pasting differences between A‐granules were established during the period of A‐granule early growth, within about 15 days of fertilization, rather than during the later period of grain filling and desiccation. Granule size distribution itself did not determine the differences observed.
