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 celebrates Kagiso Trust’s 30 years of commitment to the empowerment of impoverished communities

Future sustainable partnerships in education will survive only if all partners are committed, honest, and transparent.

This is the view expressed by the Free State MEC for Education and UFS Council member, Tate Makgoe, during the panel discussion at the Qwaqwa Campus of the University of the Free State celebrating Kagiso Trust’s 30 years of commitment to the empowerment of impoverished communities. The topic was “The future partnership models for education in Africa”.

“Over the years, the partnership between the Free State Department of Education, the UFS, and Kagiso Trust has helped to expose the potential in our mainly rural children in the Qwaqwa area of the Thabo Mofutsanyana district,” said Makgoe.

”When we started in 2009, the matric pass rate in the district was 64%, and this rose to 87% in 2014. In Qwaqwa alone, we have managed to build 51 computer and 26 physical sciences laboratories. It was these laboratories that enabled the Free State to be the best performing province in the Physical Sciences in 2013,” added Makgoe.

“None of these achievements would have been possible if all the partners had not been committed to the course. Partnerships built on honesty and transparency are the best model, which we hope to export to other provinces and, indeed, countries,” Makgoe said.

Representing the UFS on the panel was the Director of Community Engagement, Bishop Billy Ramahlele, who added that collaborations can be successful only if the leadership was exemplary.

“As the university, we have had many collaboration with various government departments, and great strides have been achieved only with the Department of Education under the leadership of MEC Makgoe,” said Ramahlele.

”With the MEC on board, the UFS ended up dedicating its South Campus in Bloemfontein to supporting Free State schools. We now have 70 schools that benefit from live television broadcasts of lessons by some of our outstanding academics. This also enables our best academics to make a valued contribution to empowering our teachers. It also allows the university to maximise scarce resources to attain social cohesion,” he said.

In his remarks, Kagiso Trust Trustee, Dean Zwo Nevhutalu, said that Kagiso Trust was looking forward to continue working with its partners to maximise outcomes through limited resources.

“Kagiso Trust will continue to work with the poor and the marginalised and there is no better partner than the government itself. The government provides basic services, and education is one of them. This allows us to be innovative and not just dump books and equipment at schools because we are forced to by our corporate social investment obligations. Therefore, we challenge the government also to be innovative in building a sustainable future partnership model in education,” he said.

Among the dignitaries attending the panel discussion were Kagiso Trust Chairman, Dr Frank Chikane, and the late Dr Beyers Naude’s family.
