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 awarded R3,6-million to train court interpreters
A contract to the value of R3,6-million has been awarded to the University of the Free State (UFS) to train court interpreters throughout South Africa.
The contract was awarded to the Department of Afro-asiatic Studies, Sign Language and Language Practice at the UFS by the Safety and Security Sector Education and Training Authority (SASSETA).
“We are the only tertiary institution in the country that offers a national diploma in court interpreting. It provides a unique opportunity to court interpreters to be trained by a group of eight lecturers who are experts in the field,” says Prof. Annelie Lotriet, associate professor at the Department of Afro-asiatic Studies, Sign Language and Language Practice.
Prof. Lotriet is an internationally renowned interpreting expert who was also responsible for the training of interpreters for the former Truth and Reconciliation Commission.
According to Prof. Lotriet no co-ordinated training programmes for court interpreters existed and there was also no control over the training processes. The programme, initiated by the Department of Justice and Constitutional Development, is managed by the SASSETA. “It is the first time that the Department of Justice and Constitutional Development initiates such an extensive training programme for court interpreters,” says Prof. Lotriet.
The group of 100 court interpreters on the programme are from all over the country. Of the group, ten are unemployed learners who interpret for the Department of Justice and Constitutional Development on an ad-hoc basis.
The programme, which stretches over two years, comprises of theoretical and service training. Contact sessions take place in Bloemfontein, Pretoria and Cape Town, four times a year for two weeks at a time. The second contact session for Bloemfontein was recently completed.
“Learners are nominated by their regional offices. The programme consists of interpreting theory, interpreting practice and basic law subjects. The training material is developed and written by the SASSETA and facilitated and presented by the UFS. The learners interpret in all the 11 languages. Some of them can speak a couple of languages each,” says Prof. Lotriet.
“Everything is going very well with the programme and we are receiving a lot of positive feedback from the learners. This first group is an experiment and it depends on their success whether the Department of Justice and Constitutional Development will expand the programme,” says Prof. Lotriet.
