Effectiveness and biochemical basis of wholemeal GlutoPeak test in predicting water absorption and gluten strength of Canadian hard red spring wheat

Abstract

Background and objectives: To further improve the efficiency of GlutoPeak test for selecting water absorption and gluten strength in wheat breeding programs, this study was conducted to investigate the suitability and effectiveness of wholemeal as testing material by eliminating flour milling process which is often the bottleneck of quality evaluation throughput. Findings: By analyzing forty-four advanced wheat lines, strong correlations were found for wholemeal GlutoPeak parameters with conventional flour-based farinograph absorption (r =.82, p.76, p.90, p
