Screening Soybean Genotypes for High-Temperature Tolerance by Maximin-Minimax Method Based on Yield Potential and Loss

Temperature rise between 2.6 and 4.8 °C will impact the productivity of soybean at turn twenty-first century. To predict differences in genotypes to high temperatures, twelve were grown greenhouses maintained a mean temperature 26, 29, 32, 35 °C, respectively, with one set natural conditions. The leaf area, total biomass, photosynthesis, Fv/Fm, pollen germination, reproductive efficiency significantly under conditions, further increase resulted decline these parameters. average seed yield 12 was 13.2 g/plant ambient there mild reduction 8% 14% when 26 29 respectively. Severe by 51% 65% observed 32 stress response index ranged from −1068 (JS 95-60) −333 (EC 538828). NRC7 EC 538828 performed comparatively better than other genotypes. Screening for high-temperature tolerance is very constrained breeding programs. This genetic variability among elevated reveals that heat can be improved through plant Additionally, it emphasizes significance identifying efficient selection strategies improving future climate scenarios.
