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 Alumni of the University of the Free State (UFS) have named Heinrich Brüssow as the Kovsie Alumnus of the Year for 2009.
At the same time, Ms Jackie Ntshingila, the Provincial Manager of the Small Enterprise Development Agency (SEDA), will receive the Kovsie Alumni Cum Laude Award, while the Executive Management Award will be awarded to Prof. Teuns Verschoor, acting Senior Vice-Rector at the UFS, and Prof. Benito Khotseng. These awards, which are made annually to honour alumni of the UFS for their exceptional achievements and contributions to the university, will be awarded on Friday, 3 September 2010.
Heinrich is currently one of the most formidable Free State Cheetahs players. During the international Super 14 Competition he was a pillar of strength for his team in many respects. He was one of the outstanding players in the match between the Springboks and the Lions. He has established himself in the triumphant Springbok team as one of the definite choices. He received the Man-of-the-Match award in the Springboks’ victory over the All Blacks on 25 July 2009, as well as the awards as the Provincial Player of the Castle SA 2009 Tournament, the SA Rugby Young Player of the Year 2009 and the 2009 Sports24 Performer of the Month.
Ms Ntshingila will receive the Kovsie Alumni Cum Laude Award for her role in the business development sector in the Free State and particularly the empowerment of women in the business sector. Her constructive inputs on various committees have lead to the outstanding role that she has played to expand SEDA in the Free State from 1 to 56 members and five branches during a relatively short period.
Prof. Verschoor will receive an Executive Management Award for the tremendous role he has played in many student matters, research, transformation and other university matters. Recognition is also given to the role that he fulfilled as acting Rector of the university during 2008-2009. In this he has emphasised his passion and commitment towards the university. In 2004 he received a Centenary Medal for management, diversity and student transformation.
Prof. Khotseng will receive an Executive Management Award for his influential and leading role during the 1990s, when the UFS was established as an outstanding institution. Prof. Khotseng played a leading and influential role as Vice-Rector: Student Affairs. He has served on the UFS Council from 1993 and in 1994 he accepted the position as Senior Manager: Strategic Programmes at Kovsies. He managed transformation and the marketing of the university in the black community with distinction. In 1995 he helped to diffuse the conflict in residences and to create a culture of learning. With the help of the Multicultural and Transformation Committees he taught persons to respect and understand one another. In 2004 he also received a Centenary Medal.
The coveted Kovsie Alumni Awards will be handed over at a Kovsie Alumni breakfast. All alumni are welcome at the breakfast which will take place in the Reitz Hall of the UFS Centenary Complex. The cost is R50 per person and includes a delicious breakfast. If you are interested in attending, please contact Annanda Calitz at 051 401 3382 or ficka@ufs.ac.za
