Assessing Plant Genetic Resources for Climate- Change Adaptive Traits Heat Traits

The vulnerability of wheat is likely to increase due to an increase of heat stress
according to recent wheat-production simulation models combined with local
climate-change data. This is particularly an issue affecting dryland areas where global
climate models all converge in forecasting temperature increase in these areas (Girvetz
et al. 2009). The greenhouse gas emissions are causing the heating up of the atmosphere
(Mendelsohn and Dinar 2009), and the combination of high temperatures and
low humidity increases the risk of heat stress for crops (Gobin 2012). Recent model
simulations with greenhouse gas emissions factored in have shown that the occurrence
of recent extreme heat waves was likely due to climate change (Herring et al. 2014).
