Advances in plant breeding and technology are reshaping grain production, but success will depend on how effectively innovation reaches farmers’ fields.
As a global agricultural science company with deep expertise in plant breeding and crop innovation, Corteva Agriscience continues to invest in technologies that strengthen productivity, resilience and sustainability in grain production.
Driaan Bresler AME seed product development lead at Corteva Agriscience, said, “Central to this commitment is ensuring that advanced research does not remain theoretical but is translated into practical solutions that deliver measurable value to farmers. Sustained progress in the grain sector will depend on how effectively innovation is integrated, scaled and aligned with on-farm realities.”
Maize yield gains reflect science in action
According to Bresler, South Africa’s maize yield trajectory reflects what is possible when science and production needs move in step. Over the past several decades, significant yield gains have been achieved through structured commercial breeding programmes, farmer collaboration and sustained research investment.
Early hybrid development laid the groundwork for improved performance and stability. As breeding methodologies advanced, genetic gain accelerated.

The introduction of biotechnology and molecular marker technologies in the 1990s marked a turning point. Genomics enabled breeders to understand plant performance at a deeper genetic level, allowing more precise selection decisions. The integration of global germplasm strengthened local breeding programmes by enabling international advances to be adapted to South African environments. These developments collectively contributed to steady productivity growth.
However, Bresler noted that production systems are becoming increasingly complex. Climate variability, evolving pest and disease pressures, and rising sustainability expectations are placing new demands on grain producers.
“Modern hybrid breeding operates within an immense universe of possible genetic combinations. Testing every combination in the field is not feasible. We understand our hybrids at a genetic level far better than ever before. The challenge is deciding which combinations to prioritise and advance,” he said.
How precision technology aids decision-making
Bresler explained that genome technologies, environmental modelling and predictive analytics now enable breeding teams to simulate crop performance across diverse and variable conditions. By combining historical field data with genomic prediction models, breeders are able to identify promising candidates earlier in the development process.
While field validation remains essential, decision-making is significantly accelerated. Technology enhances the speed of selection, but the field continues to serve as the ultimate reference point.
These tools are helping breeders refine their focus, reduce development timelines and improve the accuracy of selection, ultimately supporting more consistent on-farm performance.
One of the most promising advances lies in precision gene editing, Bresler noted.
He emphasised that technology alone will not secure the future of grain production. Integration across the value chain remains critical. Breeding strategies must align with enabling technologies, regulatory frameworks and market realities.
