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.

Within a week, the Department of Communication and Brand Management at the University of the Free State brought home two gold awards. In April this year, the department was announced as winner in the Internal Communication Category of the African Excellence Awards for the B Safe Take Action campaign. They also received Gold at the 2016 PRISM Awards for the KovsieGear entry.

PRISM Award for the UFS KovsieGear shop

Martie Nortjé, Assistant Director: Branding and Merchandise, attended the PRISM Award function in Johannesburg where she received the Gold award for the UFS KovsieGear shop for the best entry in the corporate communication category. This is the second consecutive year that the department received Gold at the PRISM Awards. Last year, the department received Gold for the B Safe Take Action campaign.

The idea for a university-owned shop was initiated in 2013. Launched in January 2014, KovsieGear is used to strengthen the brand and creating a sense of ownership among all stakeholders. The KovsieGear team is grateful for the continuous support of staff and students, as well as alumni.

The PRISM awards of the Public Relations Institute of Southern Africa (PRISA) are Africa’s most sought-after award in the public relations industry, and are presented to public relations and communication professionals who have incorporated strategy, creativity, and professionalism successfully into public relations and communication programmes and strategies, showcasing a successful public relations campaign.

African Excellence Award for B Safe Take Action Campaign

The B Safe Take Action campaign also received an award recently at a gala event hosted by the African Excellence Awards in Cape Town. Leonie Bolleurs, Project Manager of the B Safe Take Action campaign, received the award on behalf of the university.

It is of cardinal importance for the university that its students, staff, and assets are safe. Once again, this award demonstrates that the university is serious about the safety of its staff and students. This is especially so, since it is the objective of the campaign to develop a culture of safety awareness in students and staff alike.

The hosts of the African Excellence Awards are The Communication Director, the magazine for Corporate Communications and Public Relations (PR) in Europe, which enjoys worldwide distribution. According to Rudolf Hetzel, Chairman of the jury and publisher of The Communication Director, the African Excellence Awards are an opportunity for all those working in the field of PR and communications throughout Africa to come together, and honour ground-breaking communication campaigns and projects.

Quality work

“I am extremely proud of the Communication and Brand Management team for performing excellently once again in national and continental awards programmes. The awards are a good benchmark for the quality and standard of the work we produce,” said Lacea Loader, Director of the Department of Communication and Brand Management.

In the past two years, the department also received other awards for their work. This include:
-   UFS #FaceOfFacebook campaign received a Gold Quill Excellence Award from the International Association for Business Communicators (IABC), both internationally and in the Africa region.
-   B Safe Take Action campaign received a Gold Quill Merit Award from the IABC, both internationally and in the Africa region.
-   UFS #FaceOfFacebook campaign received a Bronze Stevie Award from the International Business Awards (IBA).
-   B Safe Take Action campaign received a Bronze Stevie Award from the IBA.
-    #UFStoday Facebook campaign received a Merit Award from Marketing Advancement Communication in Education (MACE).
-   The NSFAS awareness campaign received a Merit Award from MACE.
