Wheat physiology: a review of recent developments (2011, background): “…at a susceptible (Karl 92) and a tolerant cultivar (Halberd) grown at 20/188C, exposed to 1–2 days of heat (38/258C) at 10 days after pollination, Hays et al. (2007) found 25% grain abortion and 10% GW reduction in cultivar Karl, but no response whatsoever in Halberd, responses which were…”

QTL associated with heat susceptibility index in wheat (Triticum aestivum L.) under short-term reproductive stage heat stress (2010, background): “High temperature stress during reproductive development is particularly detrimental, with post-anthesis heat stress resulting in a reduction in both individual kernel weight and kernel number ( Hays et al. 2007a; Plaut et al. 2004; Randall and Moss 1990; Tashiro and Wardlaw 1990; Wardlaw and Wrigle”
Heat stress effects and management in wheat. A review (2017, background): “…(Farooq et al. 2011) and changes of hormones (Krasensky and Jonak 2012), production of oxidative reactive species (Wang et al. 2011), promotion of ethylene production (Hays et al. 2007), reduction of pollen tube development, and increases of pollen mortality (Oshino et al. 2011) in wheat.”
Genetic loci linking improved heat tolerance in wheat (Triticum aestivum L.) to lower leaf and spike temperatures under controlled conditions (2011, result): “Previous studies have shown similar levels of heat tolerance for Halberd ( Hays et al. 2007a; Mason et al. 2010) and susceptibility for Cutter (Mason et al. 2010) and Karl92 (Yang et al. 2002a), with the phytohormone ethylene appearing to play a biological role in regulating kernel abortion and see”
