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.
Five mega projects to help reposition the UFS
2008-02-01
The University of the Free State (UFS) today announced that it will focus on five mega-projects to help reposition the UFS in the next five years as one of South Africa’s leading universities that is successfully managing excellence and diversity.
Speaking at the official opening of the university today, the Rector and Vice-Chancellor, Prof. Frederick Fourie, identified the five mega projects as:
-
The successful implementation of strategic academic clusters to focus the teaching and research expertise of the UFS.
-
The development and implementation of new models of teaching and learning.
-
Finding new sources of income (including third-stream income) to minimise dependence on government subsidies and tuition fees.
-
Creating a new institutional culture for the university by finalising the Institutional Charter.
-
The ongoing transformation of the UFS in all its dimensions.
According to Prof. Fourie, the strategic clusters – initiated in 2006 – are a very important initiative which is aimed at making the UFS a world leader in six broad areas. The focus of the six clusters has now been determined. These clusters are not just research based, but will include postgraduate programmes and filter down to undergraduate learning programmes and curricula.
He also indicated that other research at the UFS will continue to be supported and funded as before.
The second project, to establish a new teaching and learning model, is meant to address current success rates which indicate the need for this issue to receive a high priority.
New income streams to enable higher levels of financial sustainability is the third project, especially in view of dwindling government subsidies and limits on student numbers. This is necessary to fund sustained higher levels of investment in the quality of academic activities and in the necessary capacity and facilities.
Prof. Fourie said the fourth project regarding institutional culture is an ongoing effort to create a sense of belonging for all staff and students at the UFS through the adoption of an Institutional Charter for the university.
“What the draft Charter does – in addition to describing overarching values espoused by the institution and its people – is to describe the outlines and constitutive principles of the ‘post-redress’ UFS,” said Prof. Fourie.
The Charter – initially launched in 2007 – is and remains a critical element of guiding transformation effectively and speedily towards a widely-accepted goal. It is a critical element of the “social sustainability and robustness” of a new UFS, especially in tumultuous political times.
The fifth project is the Transformation Plan, launched in 2007. “We simply must pursue this plan diligently, given our commitment to comprehensive and deep transformation, and to best practice transformation. All universities will have to face up to the challenge of transformation and the UFS can break new ground, as it did in the past by managing transformation innovatively and creating a campus where all can find their rightful place,” said Prof. Fourie.
