Abstract

Breeding for pre-harvest sprouting resistance in bread wheat under rainfed conditions

Highlights

Pre-harvest sprouting in bread wheat (Triticum aestivum) is a problem that occurs all over the world to varying degrees
This study aimed to provide practical information about pre-harvest sprouting resistance in wheat cultivars and to develop white kernel wheat cultivars with innately better sprouting resistance
Significant divergence was observed between treatments (T) and genotypes (G) for both percent germination (PG) and germination index (GI)

Summary

Introduction

Pre-harvest sprouting in bread wheat (Triticum aestivum) is a problem that occurs all over the world to varying degrees. The problem occurs when high humidity accompanies rainfall on standing mature wheat crops before harvest, and seeds in the spike germinate. Many early wheat scientists reported that pre-harvest sprouting is negatively correlated with yield, seed viability, seedling vigor, flour yield and baking quality[1,2,3,4,5,6,7,8,9]. Total protein and composition of amino acids accompanied by enzymatic activities are the reasons for the degradation in quality and quantity. Α-Amylases degrade starch, producing quality of bread that is below the accepted standards of consumers[12] The key reason for this is higher α-amylase activity. α-Amylases degrade starch, producing quality of bread that is below the accepted standards of consumers[12]
