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.

The Council of the University of the Free State (UFS) elected Mr Willem Louw as the new Chairperson during a special meeting on Friday 20 January 2017. He was Vice-Chairperson of the Council since 13 March 2015. Dr Nthabeleng Rammile was elected Vice-Chairperson at the same meeting, making her the first woman in the history of the university elected to this position.
The election of Mr Louw comes after the announcement by Justice Ian van der Merwe at a Council meeting on 2 December 2016 that he will be stepping down as Chairperson on 31 December 2016.
Mr Louw has served on the Council since 11 September 2009 and was elected as member of the Executive Committee of the Council on 18 November 2011. He furthermore serves on the Council’s subcommittees for Audit and Risk Management, and Honorary Degrees.
In accepting his election as Chairperson, Mr Louw said that he appreciates the trust Council has bestowed on him. “It is a privilege and honour to lead Council and I look forward to the challenge. With the support of Dr Rammile and the rest of the Council, I endeavour to ensure that the university management is assisted in the governance of the university and that the Council plays its governance role fully at all times,” he said.
“The UFS is privileged to have Mr Louw and Dr Rammile leading its Council at such a crucial time in the South African higher-education sector. Their combined experience will be of great benefit to the university community,” said Prof Nicky Morgan, Acting Vice-Chancellor and Rector of the UFS.
Mr Louw is an Associate of the Transnet Centre for Business Management of Projects at the University of Stellenbosch Business School and a non-executive Director of Group Five Limited. He was previously Managing Director of the technology business unit and a member of Group Management at Sasol, where he worked from 1985 until 2011. He is a member of the South African Council for the Project and Construction Management Professions and a Fellow of the South African Academy of Engineering. Mr Louw received his Bachelor’s and Master’s degrees in Civil Engineering from Stellenbosch University and his MDP (Management Development Programme in Project Management) from UNISA. He is currently enrolled for a PhD in Business Management and Administration at the University of Stellenbosch Business School.
Dr Rammile has served on the Council as representative of the religious communities since 1 January 2016. She is also member of the Council subcommittees for Audit and Risk Management, and Naming. She obtained a PhD in Brand Management at the UFS, where she also lectured in the Department of Business Management from 2003 to 2014. She is a pastor at Global Reconciliation, where she is responsible for women’s ministry, community outreach projects, and multimedia.
Mr Louw will serve as Chairperson of Council until 31 December 2018, and Dr Rammile will serve as Vice-Chairperson until 12 March 2018.
