Full description Post-flowering heatwaves adversely affect wheat individual grain weight (IGW) and grain quality. Their effects on IGW, yield, and grain protein content (GPC) were assessed in 25 wheat genotypes grown under irrigated field conditions across multiple locations, seasons, and sowing dates. The photoperiod-extension method (PEM) was used to synchronize flowering among genotypes, enabling heat stress to be imposed at comparable developmental stages. Genotype were also grown in adjacent machine-harvested plots to assess their crop performance under conventional field conditions. Experimental details and analyses are reported in Ullah et al. (2023, 2024) and Yahya et al. (2026).
