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.
Accreditation status of the UFS School of Medicine
2016-06-14
This communication is a factual correction of the misinformation and accompanying hysteria that appeared in a local newspaper this past week on the accreditation status of programmes in the Faculty of Health Sciences’ School of Medicine. Here are the facts:
1. The flagship programme of the School of Medicine, the MB ChB, was fully accredited by the Health Professions Council of South Africa (HPCSA) through the year 2020. This is the maximum accreditation status that any programme can achieve, and the UFS leadership is extremely pleased with this outcome, as it expresses confidence in the work done by our academics in the School of Medicine. Not only was the basic medical training for new doctors fully accredited, the HPSCA approved an increase in the number of trainee doctors from 140 to 160, and also approved additional training sites in Trompsburg and Kimberley.
2. The honours programmes of the School of Medicine received full accreditation as well.
3. All the master’s degree programmes in the School of Medicine also received accreditation. The UFS is especially pleased with the significant improvements in the Department of Cardiology, which now has a full complement of staff under the leadership of the highly regarded cardiologist, Prof Makoali Makotoko.
4. Four master’s programmes received provisional accreditation, which means that (a) these programmes continue to be taught and (b) outstanding issues, such as inadequate staffing, must be fixed. It does not mean that these programmes will be or are likely to be discontinued.
5. It is a fact that staff retire or resign in all schools and departments of any university. It is also true that these departures offer opportunities to bring new academic and professional staff into the UFS. In fact, for the first time virtually every department in the School of Medicine now has a full-time Head of Department and 46 new staff were appointed since January 2015.
6. The main employer of academic staff in the School of Medicine is the provincial Department of Health (DoH), and the UFS works very closely and persistently with the Free State DoH to ensure that vacant posts are filled.
7. The attacks on the integrity of the outgoing Head of the School of Medicine were malicious. Prof Alan St Clair Gibson did not resign ‘overnight’; his departure has nothing to do with the accreditation status of the School – in fact, he can be proud of this achievement; and he effectively takes up a promotion post in New Zealand as academic Dean at the University of Waikato. Prof St Clair Gibson will be remembered for his leadership in transformation, especially regarding staff and student equity in the School of Medicine, and for securing our programme accreditation. For this, the university is deeply grateful.
