CairoWheat loses the most grain to early heat.
Timing, not peak heat, now decides harvests for Egypt and other major wheat importers.
Researchers in the Journal of Experimental Botany found early heat exposure primes wheat to survive later heat waves.
Sowing dates and cultivar choice could be tuned against the priming effect, at almost no cost.
