Abstract:
Starch properties were measured on the doubled haploid progeny of 2 crosses, one between Cranbrook and Halberd and the other between CD87 and Katepwa. Properties studied included starch peak and final viscosity measured by Rapid Visco Analyser, starch granule size distribution measured by laser light scattering, starch gelatinisation temperature by differential scanning calorimetry, and flour swelling volume. In the Cranbrook Halberd cross (samples from 2 environments), a highly significant quantitative trait locus (QTL) was located on chromosome 4A for both starch peak viscosity and starch/flour swelling volume, centred around the
