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.
Council on Higher Education LLB qualification review not yet complete
2017-05-16
The reaction from various stakeholders following the ‘Outcomes of the National Review of the LLB Qualification’ by the Council on Higher Education (CHE) on 12 April 2017 requires the CHE to clarify that the national review process has not been completed and is ongoing.
The peer-review process conducted under the auspices of the CHE is based on the LLB Standards Document which was developed in 2014-2015 with input from higher-education institutions and the organised legal profession. Following self-review and site visits by peers, the process is now at the point where commendations and shortcomings have been identified, and the statement of 12 April reflects those findings. All law faculties and schools have been asked to improve their LLB programmes to meet the LLB Standard, and no LLB programme has been de-accredited. All institutions retain the accreditation they had before the Review process began and all institutions are working towards retaining their accreditation and improving their LLB programmes.
The South African Law Deans’ Association (SALDA) has issued a set of responses regarding the LLB programme review. The following questions and answers were published to give more clarity on the questions raised.
1. What is the effect of a finding of conditional accreditation?
The programme remains accredited.
(“Accreditation refers to a recognition status granted to a programme for a stipulated period of time after an HEQC evaluation indicates that it meets minimum standards of quality.”)
The institution must submit a progress report by 6 October 2017 that indicates how short-term aspects raised in the HEQC reports have been addressed and an improvement plan to indicate how longer-term aspects will be addressed.
2. What is the effect of a finding of notice of withdrawal of accreditation?
The programme remains accredited.
The institution must submit an improvement plan by 6 October 2017 to indicate how the issues raised in the HEQC report will be addressed, including time frames.
3. How does the finding of notice of withdrawal affect current students?
Students currently enrolled for the LLB programme at any institution are not affected at all. They will graduate with an accredited qualification.
4. How does the finding of notice of withdrawal affect new applicants?
The programmes remain accredited and institutions may enrol new students as usual. This also includes students completing BA/BCom (Law) programmes who wish to continue with the LLB programme.
5. How does the finding of notice of withdrawal affect prior graduates?
Degrees previously conferred are not affected.
6. What happens when the improvement plans are submitted in October 2017?
The CHE will evaluate the plans when they are submitted, and the programmes remain accredited until a decision is taken whether the improvement plan is sufficient and has been fully given effect to or not. The institutions will have to submit progress reports to the CHE indicating implementation of measures contained in the improvement plan.
Should a decision at some stage be taken that a programme’s accreditation must be withdrawn, a teaching-out plan would be implemented so that all enrolled students would have the opportunity to graduate with an accredited degree.
