The holy grail of potatoes

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.

Ford foundation funds higher education redesign

2005-06-23

The Ford Foundation has pledged a grant of almost R280 000 for redesigning higher education delivery at three campuses in the Free State.

According to Prof Magda Fourie, Vice-Rector: Academic Planning at the University of the Free State (UFS), the three campuses that will be affected by the strategic reconfiguration of higher education delivery are the Qwaqwa campus at Phuthaditjhaba and the Vista campus of the UFS in Bloemfontein and the Welkom campus of the Central University of Technology (CUT).

Prof Fourie says the three campuses were all affected by the restructuring of higher education, in line with the National Plan for Higher Education.

The Qwaqwa campus of the UFS that was part of the former University of the North was incorporated into the UFS in January 2003. Likewise the Bloemfontein campus of the former Vista University was incorporated into the UFS in January 2004.

The Welkom campus of the CUT was also part of the former Vista University and was incorporated into the CUT in January 2004.

“These incorporations pose a challenge in that we have to think creatively about the best ways of using these three campuses to service the higher education, training, skills development and human resource needs of the Free State,” Prof Fourie said.

“The grant from the Ford Foundation will primarily be used to draw up strategic funding proposals for the three campuses. The Qwaqwa campus of the UFS is a priority to us given the poverty and unemployment in a largely rural area of the Free State,” said Prof Fourie.

“A detailed consultation process will be undertaken in the Qwaqwa campus sub-region which will hopefully result in a comprehensive and a coherent suite of higher education activities being established on this campus,” said Prof Fourie.

“It is envisaged that the Qwaqwa campus will become a centre of excellence in the area of rural development. This vision is based on a focused integration of the core functions of a university – teaching, research, and community service – around the issue of rural development,” said Prof Fourie.

Prof Fourie said that various educational offerings including among others short courses, bridging and foundation programmes, and degrees could be offered, with a particular focus on providing courses of relevance to students from the local rural community and students from elsewhere with an interest in focusing on rural development studies.

She said the redesign of the three affected campuses is being managed as a project of the Free State Higher Education Consortium (FSHEC) consisting of all the higher education institutions operating in the Free State.

“The aim of the project is to establish how the Qwaqwa and Vista campuses of the UFS and the Welkom campus of the CUT can be used effectively to meet regional education and training needs, to serve the strategic priorities of the two higher education institutions and contribute to the sustainable development and poverty alleviation of the region,” she said.

The planning for the Vista campus of the UFS is still in an early stage. “We are looking at the possibility of developing this campus into a hub of education and training opportunities for Bloemfontein and Free State region. Further plans will be communicated later in the year,” said Prof Fourie.
