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 Rector gets reappointed
2007-06-08
The Council of the University of the Free State (UFS) today unanimously (Friday 8 June 2007) extended the term of Prof. Frederick Fourie, Rector and Vice-Chancellor of the UFS, for a further five years.
Prof. Fourie was appointed on 1 January 2003 in this position and his current term appointment will expire on 31 December 2007. The extension of his five-year term as Rector and Vice-Chancellor will come into effect on 1 January 2008. .
“During the course of his term Prof. Fourie clearly demonstrated that he has the competencies and abilities to manage the recent strong growth phase of the UFS and to further develop the UFS to be a modern university,” said Judge Faan Hancke, Chairperson of the UFS Council.
“His commitment to quality, integrity, justice, non-racialism and non-sexism are qualities that will be crucial to addressing the strategic objectives and priorities of the UFS,” said Judge Hancke.
According to Judge Hancke, Prof. Fourie’s confrontation of and commitment to two of the most important challenges facing the UFS also played a role in the Council’s decision to extend his term. These challenges are:
-
The institutional charter as key to successful, high-quality transformation and social robustness in the context of diversity; and
-
The strategic clusters as key to a word-class research and teaching profile, academic quality and robustness.
A diversely compiled committee with a balanced representivity made a unanimous decision to submit the extension of Prof. Fourie’s term to Council today for approval. The evaluation committee comprised of among others the chairperson of Council as the presiding officer, the vice-chairperson of Council, other Council members who are not employees of the UFS and representatives of Senate.
The process comprised of the evaluation of Prof. Fourie’s work performance and competencies within a broad framework of the strategic aims of the UFS.
According to Judge Hancke the evaluation committee considered aspects such as the staff profile of the UFS; the vision, mission, values and strategic priorities of the UFS and Prof. Fourie’s vision for the UFS; the inherent post requirements of Rector and Vice-Chancellor; the outcome of the evaluation discussion with regard to Prof. Fourie’s successes during his term as Rector and the future challenges for a rector before the recommendation was made to Council.
“On behalf of Council I wish to congratulate Prof. Fourie with his appointment and wish him all of the best with his task to take the UFS to new heights,” said Judge Hancke.
