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 in partnership with USA ’s Council on Economic Education 

A group of 50 teachers in Economics, learning facilitators and lecturers from eight countries attended a ‘train the trainers’ workshop this past week in Bloemfontein.  The workshop forms part of the outreach programme of the National Council on Economic Education (NCEE) in the United States of America’s (USA) effort to improve the quality of the training in Economics of teachers and lecturers across the world. 

The UFS and the Free State Department of Education are the NCEE’s first partners in Africa.  “The initiative started in the Free State because of the connection that existed between the UFS and the NCEE,” said Prof Klopper Oosthuizen, from the UFS Department of Agricultural Economics and initiator of the cooperative agreement with the NCEE.

Three faculties at the UFS are involved in the cooperative agreement namely the Faculty of Natural and Agricultural Sciences, the Faculty of the Humanities and the Faculty of Economic and Management Sciences.

A group of 84 teachers and learning facilitators in the Free State attended the ‘train the teacher’ workshop at the UFS in December 2005 in an effort to improve the quality of Economics classes at schools in the Free State.  The last national workshop will take place in June 2006 in Bloemfontein.  During this workshop a group of 40 teachers and learning facilitators in the Free State will be trained by the NCEE.    

“Because of the success with the programme in the Free State Dr Patty Elder, Vice-President of the NCEE’s national programme, announced during last week’s workshop that the initiative will now be extended to the other provinces in the country,” said Prof Oosthuizen.  According to Prof Oosthuizen discussions around a strategy to get the other provinces on board of the programme also took place between Dr Elder and Prof Herman van Schalkwyk, Dean of the UFS Faculty of Natural and Agricultural Sciences.  Prof van Schalkwyk will take the lead in this regard.  

“The presence of Dr Elder and the executive directors of similar education networks in the Ukraine and Indonesia is an indication of the NCEE’s seriousness with the programme in Africa,” said Prof Oosthuizen.

Prof Oosthuizen explained that South Africa is competing to obtain funds from the NCEE to have a total South African representation in the workshops in the following one-year training period. 

South Africa has a good chance of establishing the network quickly because of the presentation of the last national workshop in Bloemfontein in June 2006.  “We are going to try to have as much South African representation as possible at this workshop,” said Prof Oosthuizen.

Concurrent with the workshop in June 2006, a programme will be developed that will be attended by at least five other provincial education departments and representatives of five other universities.  These representatives will then be able to observe on a first-hand basis how this action learning takes place and how the participating countries plan to establish and expand their networks,” said Prof Oosthuizen.

“The NCEE has been working together with international partners since 1992 to strengthen their Economics teaching systems.  They have already succeeded in increasing literacy in Economics of schools in the USA and more than 20 East Block countries.  More than 1,5 million learners in the East Block countries have already been served by this initiative,” said Prof Oosthuizen.

According to Prof Oosthuizen the focus of the NCEE has since 2004 moved away from the East Block countries to Africa, Asia, Latin America and the Middle East.  The representatives that attended last week’s workshop were from South Africa, Egypt, Jordan, Palestine, Indonesia, Mexico, Paraguay and Uruguay.  Countries such as Egypt, who was also present at last week’s workshop, are eager to start a similar network.
