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 Council elects a new Chairperson

The Council of the University of the Free State (UFS) elected Judge Ian van der Merwe as its new Chairperson at its last meeting for this year on Friday, 20 November 2009.
Judge Van der Merwe is an alumnus of the UFS and has been a member of the Council since 9 March 2007. In accepting his appointment, Judge Van der Merwe said that he was honoured and humbled to lead a Council of this calibre. “I will always do what is in the best interest of the UFS and, together with the Council, I will work towards making it an autonomous institution of academic excellence that is non-racial, non-sexist, and where diversity is cherished,” he said.
The election of a new Chairperson and the term of the Chancellor were among the matters discussed during yesterday’s meeting.
Dr Franklin Sonn will retire as Chancellor on 31 December 2009 and the term of office of the current Chairperson of Council, Judge Faan Hancke, will also expire on 31 December 2009. Dr Sonn has been Chancellor since 7 February 2003 and Judge Hancke has been Chairperson of the Council since 1 June 2001.
“I am elated that someone of Judge Van der Merwe’s stature has been elected as Chairperson and will provide him with my full support,” said Prof. Jonathan Jansen, Rector and Vice-Chancellor.
The Council paid tribute to Judge Hancke for the time he dedicated to the UFS, as well as for his leadership, guidance and wisdom to take the institution to where it stands in the current phase of its history. The Council also recognised Judge Hancke for, amongst others, his decision to appoint Prof. Jansen as the first black Rector and Vice-Chancellor, for his role in the implementation of the Transformation Plan and the policy to increase diversity in residences at the UFS, as well as his contribution to the growth of black students.
Judge Hancke thanked the Council for their support and assistance during his term and congratulated Judge van der Merwe on his appointment. “I wish Prof. Jansen and his management team well and hope that they will have the wisdom to solve the problems the institution is facing so that they can focus on the core business of the UFS namely its academia. I know the University can make a tremendous contribution to the country,” he said.
The Council also welcomed the following new members who were present at the meeting: Mr Pule Makgoe, MEC for Education in the Free State; Mr Ndaba Ntsele, Chief Executive Officer of the Pamodzi Group and Mr Willem Louw, Managing Director of Sasol Technology.
The new Chancellor will be elected as soon as the proposed statute is approved by the Council in 2010 and published in the Government Gazette. Prof. Jansen will act as Chancellor for the interim period from 1 January 2010.
