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.
State of our campuses: UFS Qwaqwa Campus temporarily closed until 18 April 2017
2017-04-03
The senior leadership of the University of the Free State (UFS) has decided to close the Qwaqwa Campus on Tuesday 28 March 2017 due to student protests regarding provisional registrations. Academic activities will resume on 18 April 2017.
The protests were preceded by a meeting of the campus management with the Student Representative Council (SRC) on 22 March 2017 to discuss issues pertaining to students who are provisionally registered – especially those students who are provisionally registered and awaiting the outcome of their appeals to the National Student Financial Aid Scheme (NSFAS).
On 27 March 2017, the SRC handed a memorandum to the campus management, requesting assistance in cases that are on appeal with NSFAS. The students also demanded extension of the provisional registration deadline of 31 March 2017, and that a fundraising plan should be implemented for financially needy students. The campus management made a commitment to respond within the deadline stipulated in the memorandum.
After the meeting, violence erupted when a group of students started intimidating students, barricading the entrance to the campus, and damaging university property. An interdict was served by the Sheriff later the same afternoon and additional security was deployed. On 28 March 2017, the violent protests and barricades spilled onto the provincial road to Phuthaditjhaba and several cars were damaged. This led to the arrest of a number of students by members of the South African Police Service for the contravention of the High Court order and for public violence. The students have since been released.
Due to the imminent threat to the safety of staff and students on the campus, the senior leadership decided on 28 March 2017 to evacuate the residences and to close the campus temporarily until 18 April 2017.
“It is unfortunate that the students resorted to violence without waiting for the campus management’s response to the memorandum of 27 March 2017. What makes the situation difficult is the fact that students on provisional registration who are waiting for the outcome of their NSFAS appeals, are dealing directly with NSFAS. This makes it difficult for the university to intervene,” says Mr Teboho Manchu, acting Principal of the Qwaqwa Campus.
The senior leadership of the UFS is aware of the video clip on social media this week, where a student is allegedly beaten by security guards on the Qwaqwa Campus. The senior leadership condemns this deplorable incident. An investigation is underway to determine the nature and cause of the incident. Appropriate steps will be taken once the outcome of the investigation is available.
