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.
Student Transformation Forum kicks off

The establishment of a Broad Student Transformation Forum (BSTF) at the University of the Free State (UFS) was initiated yesterday with a student consultative forum called to determine the agenda and delegations to the BSTF.
The establishment of the BSTF follows the suspension of the functioning of the Student Representative Council (SRC) recently and aims to provide students broadly with the opportunity to reach consensus regarding student governance at the Main Campus in Bloemfontein.
The meeting was chaired by student affairs specialist Prof. Cecil Bodibe and was attended by representatives from student associations from all faculties, representatives of non-faculty student associations and representatives from residences. Commuter students were represented through private student associations.
“The meeting clearly expressed agreement that decisions taken by the BSTF should ensure that the student body and student-life programmes truly reflect our constitutional commitment to building a non-racial, non-sexist and democratic society, and that collaboration between students and management in affecting the decisions of the BSTF to achieve this should be prioritised,” Mr Rudi Buys, Dean of Student Affairs, said.
The forum agreed that apart from addressing specific questions pertaining to student governance, the BSTF should also address transformation issues broadly. The forum also agreed that the delegations to the BSTF should ensure that the forum is truly representative of the diverse student population and is inclusive of all stakeholder groups, including international students and students with disability. A proper process to determine the credentials of participating association was requested and will be implemented.
The meeting furthermore expressed the wish that the BSTF should exist only to determine the key changes that should be made to student governance now, so that the postponed SRC elections may continue as soon as possible. The BSTF will thus have a temporary role to enable the student body to reach consensus regarding changes to the SRC constitution.
Meanwhile, an Interim Student Committee (ISC) was appointed, which has the role to ensure the continuation of daily student life programmes and to ensure student representation in management and governance of the university continues during the deliberations of the BSTF. The ISC serves as an interim structure that will dissolve when a new SRC takes office following the outcome of the BSTF and the continuation of the SRC election.
The ISC consists of 15 members who were appointed through a process of nomination of four (4) members each from the faculty-student associations, non-faculty student associations and from residences, and three (3) members from the student executive committees of Kovsie Community Service, the Irawa student newspaper and the Kovsie Rag executive committee.
The ISC elected Ms Modieyi Mothole and Ms Nida Jooste as its chairperson and deputy-chairperson, respectively.
“I’m encouraged with the initiative and response of students to ensure student governance continues, which bears witness to the depth of leadership our student body holds, while the level of engagement by students in the BSTF indicates that the student body seriously consider issues of transformation,” said Mr Buys.
