This project will reveal the underlying physiological processes responsible for variation in metabolic heat tolerance among 58 Corteva/Pioneer ERA hybrid lines of maize.
About
Goal: This project will reveal the underlying physiological processes responsible for variation in metabolic heat tolerance among 58 Corteva/Pioneer ERA hybrid lines of maize. Since 1930’s, hybridization has been shown to improve overall maize productivity through, for example, improved drought tolerance, nutrient uptake and use efficiency, beneficial changes in crop morphology and development, and biomass partitioning. However, no study to date has explicitly characterized the effects of the long-term breeder selection on physiological heat tolerance of key leaf carbon exchange processes among maize ERA hybrids.
Key Benefits
An enhanced understanding of the factors that drive variation in heat tolerance in maize ERA hybrids, with that knowledge informing Corteva’s future breeding efforts aimed at developing heat-tolerant varieties
Applications
Agriculture
