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 University of the Free State (UFS) was this week recognised by the United Nations (UN), as well as the national association for Marketing, Advancement and Communication in Education (MACE), for its communication and marketing publications and campaigns.
The UFS was named by representatives of the UN to receive a special United Nations Award for a leadership communication campaign called ‘Talk to me’. The award, which forms part of the Golden Awards of the International Public Relations Association (IPRA), is made annually to the campaign that best supports human development in line with the UN objectives.
The UFS also received seven awards from MACE during the Higher and Further Education Excellence Awards. The ‘Talk to me’ campaign was awarded an Excellence Award in the category integrated campaigns and projects; a television campaign on DSTV received an Excellence Award in the broadcasting category. The campaign also received an award as the overall winner in this category. The magazine Bult received a special Excellence Award in the category external publications (as the publication with the highest marks in the history of this award ceremony); the staff newsletter Dumela and a set of student recruitment publications each received a Merit Award in the categories internal newsletters and special publications respectively; and the Open Day campaign received a Merit Award in the category integrated campaigns and projects.
The Excellence Awards form part of the 2013 national MACE congress, which was hosted by the UFS on the Bloemfontein Campus from 18-20 November 2013 and attended by 139 delegates from 25 higher and further education institutions.
“I am extremely proud of the achievements of what is emerging as a truly world-class communications department at the UFS recognised increasingly for achievements nationally and abroad,” says Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.
‘Talk to me’, which was implemented in 2010, is a leadership communication campaign that creates a way for staff and students to engage with Prof Jansen. With the campaign, he regularly spends time physically sitting on the university’s three campuses in a predetermined area giving staff and students the opportunity to talk and interact with him. The success of the campaign stems from the fact that it gives him the opportunity to pick up on issues or concerns of the campus community.
“The ‘Talk to me’ campaign is one of the key campaigns of the university’s Human Project, as it projects the scholarship of service and transformation leadership. It is an exceptional honour to be recognised by the UN and to receive this award,” says Lacea Loader, Director: Strategic Communication at the UFS.
“The MACE Higher and Further Education Excellence Awards provide an excellent platform to showcase the many projects and campaigns of the sector, and to receive this kind of recognition from our peers is a tremendous honour for the UFS,” says Loader.
