Abstract

[Introduction]: Extreme temperatures can cause severe reductions in wheat yield, including in Australia where temperatures are highly variable within and across growing seasons. A single post head-emergence frost (PHEF) event has the potential to devastate individual wheat crop by damaging stems and killing whole head.

Management of crop phenology to avoid PHEF is very important in many parts of the world where frost risk is high. Breeding for improved reproductive frost tolerance could allow greater yield and economic benefits to be achieved, by (i) reducing direct frost damage and (ii) allowing earlier sowing to reduce risks of late-season drought and/or heat stresses (Fig. 1). This study aims to provides insights into the frost impact and economic benefits of different improved frost tolerance levels across the Australian wheatbelt.
