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 unveils portrait of Ms Winkie Direko

UFS unveils portrait of Ms Winkie Direko
A portrait of Ms Winkie Direko, former Chancellor of the University of the Free State (UFS) and Premier of the Free State Province and currently a Member of Parliament, was unveiled today during the last session of the UFS Council for this year on the Main Campus in Bloemfontein.

The portrait, painted by the gifted artist Ms Reshada Crouse, now hangs in the Council Chambers of the UFS.

Ms Direko was sworn in as Chancellor of the UFS in August 1999. She was the first black person and first woman in this position at the UFS. She was succeeded by Dr Franklin Sonn.

“Ms Direko had an exceptional legitimacy in the black community because of her role in black education in the Free State (as principal) and community leader in the difficult ‘struggle’ period. This former principal’s simultaneous insistence on transformation as well as discipline and order at an educational institution was exactly what the UFS needed at that stage,” said Prof Frederick Fourie, Rector and Vice-Chancellor, during the unveiling ceremony.

“She also played a special role to bring the UFS and the Free State Provincial Government closer to each other. Her comprehension for the own nature of a university helped in times when difficult decisions had to be made. She also realised the value of the university’s expertise for her government. The Premier’s Economic Advisory Council, with the UFS rector and academics like Lucius Botes and James Moses in leading roles, was formed to undertake important research on economic development strategies in the Free State,” said Prof Fourie.

In her speech Ms Direko said that it is an unique experience for her to be catalogued in the history of the UFS. “I am humbled and proud to be associated with the UFS,” she said.

Ms Direko said that the UFS is on the right track with its transformation process. “I will continue to convince people that the UFS is for everyone and will fight for that until the end. But, it is important to see a visible change concerning transformation. The UFS must bring its side and speed up the transformation process. I know that it is a difficult road, but we cannot hide from the realities of our time,” she said.
