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.

This week Dr Anna de Jager received her doctoral degree in Religious Studies: Biblical and Religious Studies, during the Spring graduation ceremony of the University of the Free State (UFS) that took place in the Callie Human Centre on the Main Campus in Bloemfontein. Dr De Jager was the star of the day because she was the oldest person (93) who received her qualification during this graduation ceremony. The theme of her thesis is: Die belewing van geloofsekerheid by die Gereformeerde Afrikaanssprekende adolessente leerder.

| UFS honours an acclaimed educational researcher |
 |
|
The University of the Free State (UFS) conferred an Honorary Doctorate to Prof. Andries Hermanus (Kalie) Strydom during the Spring graduation ceremony held at the Callie Human Centre on the Main Campus today. Prof. Strydom is an alumnus and former academic of the UFS. His academic career can best be described as a lifetime of dedication to accountable research aimed at the advancement of higher education in South Africa. He is an acclaimed researcher in the field of higher education – nationally and internationally. His work over the last 30 years has not only been about supporting transformation in the education sector and specifically higher education, but also about capacity building of staff and supporting equity expectations without compromising quality.

The University of the Free State (UFS) conferred another Honorary Doctorate today, this time on Dr Monty Jones (pictured), a Sierra Leonean who spent the last 32 years of his career in Africa working in international agricultural research for development institutions. Dr Jones is the Executive Director of the Forum for Agricultural Research in Africa (FARA) and co-winner of the prestigious 2004 World Food Prize. The UFS also awarded 300 degrees and 21 doctorates to students from the Faculties of Economic and Management Sciences and Natural and Agricultural Sciences; and 274 diplomas were conferred on students from all the faculties during the Spring graduation and diploma ceremonies on the Main Campus.

| UFS reaches another milestone in Sign Language |
 |
|
The University of the Free State (UFS) has become the first university in South Africa to award a Ph.D. in South African Sign Language. This honour was bestowed upon Dr Philemon Akach (pictured), Head of the Department of South African Sign Language at the UFS, during the Spring graduation and diploma ceremonies on the Main Campus. The UFS is also the first university in the country to have a fully-fledged and dedicated Department of South African Sign Language and it was the first university on the continent to offer Sign Language as an academic course in 1999.

The Department of Chemistry at the University of the Free State (UFS) bore witness to a special event on Thursday, 16 September 2010 when another Conradie of the department received her doctoral degree. Marianne Conradie, daughter of Prof. Jeanet Conradie of the department, obtained her doctoral degree during the UFS’s 2010 Spring graduation ceremony. Adding to the already tight family connections, Prof. Conradie also acted as the promoter for Marianne’s thesis titled Rhodium and Iron complexes and transition states: A computational spectroscopic and electrochemical study.
