The holy grail of potatoes

Scientists are actively pursuing the successful breeding of diploid hybrid potatoes from inbred lines. This is expected to revolutionise potato breeding as it holds the key to rapid genetic progress. It will introduce new varieties for commercialisation through seed. Currently, existing potato variants have a gene that renders self-pollinated seeds infertile.

Prof Linus Franke, an academic in the Department of Soil, Crop and Climate Sciences at the UFS, is leading the research in South Africa. “This technology allows the production of genetically uniform potato seed that is easy to transport and largely disease-free.” He says this differs from conventional breeding whereby only vegetative propagation is possible due to tetraploid varieties in potatoes. It also risks carrying pests and diseases from one generation to the next – leading to the accumulation of pests and diseases with each round of multiplication.

Seed innovation

Prof Franke explains that Solynta BV, a seed company based in the Netherlands that produces potato varieties that can be grown from seed, has included South Africa in their research efforts because it is one of Africa’s largest producers and exporters. Through his academic relationship with Wageningen University and Research, a Dutch institution renowned for its agricultural endeavours and food production, the UFS became involved in researching hybrid potatoes grown from seed.

Diploid seeds containing two sets of chromosomes allow easier gene manipulation to increase predictability and speedier genetic progress. The breeding approach enables the incorporation of tolerance to pests, diseases, abiotic stresses (cold, heat, drought) and other desired genetic traits.

Although Prof Franke is optimistic about this research, he is not blind to disadvantages. “Potato seeds are tiny and have little energy reserves, making it harder to grow potatoes from seed than from tubers.” He says potatoes from seed will take longer to cultivate than tubers, as farmers need to grow plantlets from seeds first, adding six weeks to the growing period. “It is possible that commercial farmers can grow potatoes directly from seed. Alternatively, perhaps more likely, specialised growers will produce tubers of potatoes from seed; these tubers are then sold as seed tubers to other potato farmers, who then continue their normal practices of producing potatoes for the market from tubers.”

Financial benefits

Prof Franke says farmers have reason to get excited. “Seed potatoes will reduce input costs, as varieties with enhanced tolerance to pests and diseases require less pesticides. Planting one hectare of potatoes requires three to four tonnes of potato tubers, but only one 25 g packet of potato seeds.” Since potatoes are a more valuable commodity than maize, this technology might also increase farmers’ income potential.

UFS students excel at FPI awards

Two top achievers from the Centre for Financial Planning Law at the University of the Free State (UFS) were crowned nationally as top students by the Financial Planning Institute of Southern Africa (FPI) at a gala ceremony at Emperor’s Palace, Johannesburg, on Tuesday night.

Annemarie Trinder-Smith, a financial planner at Christo Saayman Financial Planners, was the best student in the Postgraduate Diploma in Financial Planning, while Renier de Bruyn, financial advisor at PSG Consult (George) was the best student in the Advanced Postgraduate Diploma in Financial Planning.

They were among 461 students of the Centre for Financial Planning Law at the University of the Free State (UFS) who earlier received their postgraduate diplomas at a ceremony that formed part of the annual FPI convention.

The Centre for Financial Planning Law, which was established in 2001, was the first and for five years the only academic centre in South Africa to present a Postgraduate Diploma in Financial Planning. Today the UFS is still the only institution to present this course through distance learning. The UFS is currently the only institution that offers the Advanced Postgraduate Diploma in Financial Planning.

At the diploma ceremony hosted earlier by the UFS, the following students were named as top achievers in various modules of the Postgraduate Diploma in Financial Planning:
• Mylie Archibald (Financial Planning Environment, Corporate Financial Planning)
• Shaun Matthews (Personal Financial Planning)
• Nicolette van der Linde (Financial Planning Case Study). She also received an FPI prize as top student.

In the Advanced Postgraduate Diploma in Financial Planning, the following students were named as top achievers in various modules by the UFS. They also received FPI prizes in these modules:
• Megan Joan Anika (Fund Governance and Maintenance)
• Sarah Lynn James (Fund Design and Financing)
• Melanie Louw (Personal Risk Management)
• Renier de Bruyn (Estate Planning, Asset Types and Investment Planning)
• Jan Willem Wessels (Principles of Portfolio Planning and Management)

According to Adv Wessel Oosthuizen, Director of the Centre for Financial Planning at the UFS, large companies, banks, insurers and investment managers enroll their staff for these qualifications.

“The two diplomas form the basis for financial planners, brokers, lawyers and bankers to be recognized as certified financial planners - the CFP® status - as well as obtaining membership of the FPI.”

“A qualified financial planner, especially a CFP®, is one of the most sought-after titles in the financial planning sector worldwide. With about 3 700 CFP’s, South Africa has the fifth highest number of certified financial planners in the world,” Adv Oosthuizen said.

Adv. Oosthuizen is well-known nationally and internationally for his contribution to the advancement of financial planning law and financial planning education.

He was recently invited by the Financial Planning Standards Board to serve on an international committee that will evaluate the quality of education in financial planning. He was also the chairperson of a working group that developed guidelines for a standardised international curriculum for financial planners.
