Mitigating the risk of pre harvest sprouting in canadian malting barley

Crop Types

Background

The need for rapid and uniform germination in malting barley has led to the development of commercial cultivars that have minimal dormancy, which is good, but these cultivars are therefore highly susceptible to Pre Harvest Sprouting (PHS). This along with occurrence of wet summer conditions at or near harvest has made PHS a concern in the production of high quality malting barley. This project is aimed at identifying germplasm lines and novel candidate genes/molecular markers that provide a unique opportunity for efficient and directed breeding of malting barley cultivars with optimum dormancy.

Objectives

  1. Identify and map genomic regions associated with resistance to preharvest sprouting
  2. Identify novel candidate genes for preharvest sprouting resistance in malting barley
  3. Investigate allelic variations and expression patterns of candidate genes controlling resistance to preharvest sprouting
  4. Examine variations in abscisic acid level among selected malting barley lines
