Current frost phenotyping methods used within the Australian National Frost Program (ANFP) are based on frost induced sterility at flowering... This estimation of varietal response to frost assumes the reduction in grain number is the main yield component affected... There has been limited work evaluating the effect of frost induced sterility on yield components (grains per m2, spikes per m2 and grain weight) and final grain yield or for variation in this under frost...

Catalogue: GRDC Final Reports
The aim of this project was to develop standardised frost screening protocol that could then support future frost research for the Australian grains industry... The results showed that following a discriminatory frost event, the developed methods were able to reliably rank the frost tolerance of wheat and barley varieties... QTL mapping results from the current GRDC project UA00114 have identified that the QTL controlling frost tolerance on the group 2 chromosomes of barley and wheat are most likely related...
