Pioneer South Africa hosted its 2026 Canola Grower Days near Swellendam and Riebeek-Kasteel in the Swartland as part of the company’s centenary celebrations. The event brought together canola growers, agricultural stakeholders, producers, trading partners, and Pioneer/Corteva representatives from South Africa and abroad.
Plaas Media attended the event at Joubertsdal Country Estate, where discussions focussed on the future of South Africa’s canola production, seed technology, genetic progress, practical agronomy, integrated crop management, and the challenges producers face. In addition to celebrating a century of plant breeding innovation, the event also provided an opportunity to look ahead and consider how the next generation of canola genetics, combined with stronger producer partnerships, can support improved yields, resilience, and long-term farm profitability.
Pioneer used its 100-year milestone to highlight how global breeding programmes, combined with local agronomic expertise, can help develop canola genetics suited for increasingly demanding production environments. Caria Grobler, marketing manager at Pioneer SA, showed a video tracing Pioneer’s humble beginnings in 1926.
A century built on genetics
Pioneer’s story began in 1926, when Henry Wallace planted the seed that would ultimately grow into a global agricultural business. He was an early advocate of improving crops through genetics, establishing a foundation that continues to influence Pioneer’s breeding approach today. The company’s long-term philosophy, known as the ‘Long Look’, remains centred on four core principles: developing high-quality products, conducting business honestly and fairly, communicating product performance accurately, and helping producers achieve greater profitability.
That philosophy has evolved into a ‘farmer first’ approach, with product development and agronomic support aimed at practical challenges in the field. This includes insect and weed pressure, disease, drought, heat stress, changing weather patterns, and the rising demand for food, feed, and renewable resources.
The significant increase in crop productivity over the past century illustrates the importance of genetics. Pioneer speakers referred to maize as an example of what sustained genetic improvement can achieve. The average US maize yields have increased substantially since the early days of hybrid breeding; however, record yields show that genetic potential remains considerably higher than average commercial yields. The same principle applies to canola.
Open-pollinated varieties to hybrid canola
Pioneer’s global canola breeding programme began in Europe in 1989, expanding to North America in 1990 and Australia in 1995. It launched its first hybrid canola products in 2003, marking a shift from open-pollinated varieties to hybrid genetics. Pioneer canola entered South Africa around 2010 and shifted its portfolio towards hybrids in 2013. According to Adam Anderson, supply chain director at Corteva Agriscience, the company combines global breeding expertise with regional testing to ensure products perform under local conditions.
Breeding and production environments in Canada, Europe, and Australia contribute to the global programme, with genetics tested in markets such as South Africa. The strategy has also expanded into new markets, including Uruguay, with Argentina planned for the future. This global network enables Pioneer to combine genetic resources from diverse environments while maintaining a focus on local performance. Anderson noted that hybrid canola remains relatively young compared with crops such as maize, leaving significant scope for further genetic improvement.
Rather than setting a fixed yield ceiling, Pioneer aims to close the gap between genetic potential and actual field performance. Drought, heat, disease, insects, and other environmental stresses progressively reduce yield potential after planting. The company is therefore pursuing sustained genetic gain through new technologies and breeding approaches. Anderson stressed that genetics alone will not close the yield gap. Improved management and better in-season decision-making will also be essential to realise the potential of new hybrids.
A major disease challenge
During the grower day in Swellendam, Piet Lombard highlighted blackleg as a major challenge in South African canola production. Because blackleg can overcome resistance, it remains a long-term management issue requiring an integrated approach. Drawing on Australian research, supported by Canadian data, he stressed the importance of understanding the different types of genetic resistance available in canola. Major resistance genes can provide strong protection, but pathogens may adapt and overcome individual resistance mechanisms.
Quantitative resistance, which is controlled by multiple genetic factors, offers another layer of more durable, partial resistance. “The greater the level of quantitative resistance in a cultivar, the greater its potential contribution to disease management,” Lombard said. Genetics should be combined with crop rotation, cultivar selection, strategic planting dates, and fungicides where economically justified. Rotation allows infected residues to break down, while strategic planting dates can reduce disease risk. Fungicide resistance further reinforces the need to avoid relying on a single control method.
The goal is not to achieve a disease-free crop, but rather to implement economically effective disease management strategies that protect yield and maximise returns. Repeatedly planting susceptible or genetically similar cultivars, continuous canola production and reliance on the same fungicide chemistry can increase selection pressure on pathogens. The long-term solution is to manage the entire production system instead of relying on only one tool to manage diseases.
Seed availability
During the event, producers raised questions regarding the availability and production of Pioneer canola seed in South Africa. Although the local market is growing rapidly, it remains relatively small compared to some of the company’s major international markets. Pioneer expects its production and supply strategy to evolve, as demand increases. Hybrid seed production introduces unique challenges, requiring suitable isolation and reliable production conditions. Pioneer has consequently invested in changes to its production systems and inventory strategy to improve supply reliability across South Africa.
At present, Australia remains an important seed supplier for the South African market. Pioneer’s global production scale allows the company to respond quickly to local supply requirements and evaluate opportunities to develop its supply network. Reliable seed availability will remain essential as the South African canola market expands.
Looking at the next 100 years
Pioneer’s breeding strategy extends far beyond yield. The company’s development pipeline targets traits designed to improve crop stability and profitability under increasingly variable conditions. These include:
- Improved resistance to diseases such as blackleg, Sclerotinia, Verticillium, and clubroot, together with enhanced insect protection and new approaches to manage weeds.
- Herbicide resistance. Pioneer is investigating different methods and genetic approaches to help producers manage resistant weeds.
- Improved tolerance to extreme weather. Heat stress, drought, and winterkill can significantly affect yield. This makes stability and resilience a priority, alongside maximum yield potential.
Pioneer’s research pipeline combines conventional breeding, native genetics, transgenic technologies, and emerging gene-editing tools, depending on market needs and regulatory environments. Research is also looking beyond oil yield to improve the value of canola meal by increasing protein concentration and reducing indigestible fibre. The goal is to enhance its nutritional value for it to be used in poultry, pork and aquaculture industries, alongside traditional ruminant feed markets.
Pioneer’s centenary highlighted continuous genetic gain as a powerful tool for producers. For South African canola producers, the opportunity lies in combining improved genetics with sound agronomy, disease management, responsible chemical use, and reliable seed supply to narrow the gap between genetic potential and commercial yield.
The challenge is to translate breeding advances into practical, locally adapted products that perform consistently under real farming conditions, with the ultimate goal of better genetics, better management, and more profitable, sustainable farming systems.
