Leading the research in South Africa is Prof Linus Franke from the Department of Soil, Crop and Climate Sciences.
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 will increase its volume of quality research

The University of the Free State (UFS) is taking its research serious and is therefore going to increase its volume of quality research. This includes the production of quality scholarly books in the humanities and social sciences.
This was said by Prof. Jonathan Jansen, Rector and Vice-Chancellor, at the launch of the Strategic Academic Cluster initiative of the University on the Main Campus in Bloemfontein last night.
“We are going to produce the kind of research that is associated with scholarships. New models of training, new standards of performance and the introduction of an accelerated Vice-Chancellor’s Prestige Scholars’ Programme are among the initiatives that will be introduced. These are all aimed at boosting our university’s research performance,” said Prof. Jansen.
Another strategy to boost research performance at the UFS is the search for 25 leading professors to be appointed across the disciplines, but especially in the social sciences, education and the humanities. These positions have already been advertised and will be phased in with the goal of achieving equity and excellence in the academic and research profile of the UFS. “We’ve had an overwhelming response to the advertisements from local academics as well as those abroad,” said Prof. Jansen.
Each of the six Cluster Directors gave a short presentation of its aim and focus areas during last night’s dinner. These Clusters will in future direct the University’s research endeavours. It represents a move from a fragmented to a more focused approach to research development at the UFS.
The UFS also signed a memorandum of agreement with Cornell University (USA) last night. The guest speaker, Prof. Alice Pell, Vice-Provost: International Relations at Cornell University and member of the UFS’s International Advisory Board, said that, just as the cluster research teams need representatives from different disciplines, universities need diverse partners to recognise their potential fully. Collaborating with partners with ‘fresh eyes’ that have different cultural perspectives, access to different technologies and partners with different priorities can have important implications in the research and education provided by the UFS and Cornell,” she said.
“The interdisciplinary approach adopted by the UFS in developing the Strategic Academic Clusters seems likely to provide students with the intellectual frameworks and research tools that they need to address the problems in society,” she said.
“The most important issues facing the USA and South Africa are similar, namely how to effect the social transformation that will provide equal opportunities to all of our citizens. South Africa, Brazil, India and the USA share strong commitments to democracy, to overcoming our dark histories of religious and racial discrimination and to sustainable economic development without adverse impacts on our planet. We at Cornell are excited about the opportunity to work with the UFS on all of the clusters, but we are particularly looking forward to learning more about social transformation,” said Prof. Pell.
