Wheat varieties differ in response to natural heat events during the early reproductive stage locations
Aims

The study determined whether genetic differences in tolerance can be idenified in field grown wheat exposed to natural heat events at the early reproductive stage of development.

Key messages
  • The most intense of three heat events avegarged 35.5 degrees celcius and reduced grain numbers per spikelet by 21%.
  • Significant genetic variation was observed for floret sterility induced by natural heat events. The variety Halberd was identified as most heat tolerant and Westonia as most heat sensitive.
  • The results indicate a genetic variation that could be exploited to improve wheat crop resilience under heat stress.
