Puroindoline genotype, starch granule size distribution and milling quality of wheat
چکیده انگلیسی

Genetically-diverse wheat samples from the Australian Winter Cereals Collection propagated in two environments were sequenced to identify puroindoline genotypes then the relationships between flour yield, genotype, starch granule size distribution and starch-bound puroindoline protein content were investigated. The Pina-D1a, Pinb-D1b genotype resulted in a higher average flour yield than either the Pina-D1b, Pinb-D1a or the Pina-D1a, Pinb-D1a but the ranges of flour yields for the three genotypes showed considerable overlap. For both hard wheat genotypes (Pina-D1a, Pinb-D1b or Pina-D1b, Pinb-D1a), a higher proportion of type A to type C starch granules was associated with higher flour yield and this relationship accounted for between 31% and 33% of the variation in flour yield. This result is consistent with previously reported findings for soft wheat. For the Pina-D1a, Pinb-D1b genotype, increased flour yield was also associated with a decrease in starch granule-bound puroindoline protein, which accounted for 31–35% of the variation in flour yield across the two environments. The combined effect of starch granule type and associated puroindoline content accounted for 68% of the variation in flour yield within the Pina-D1a, Pinb-D1b genotype.
