The holy grail of potatoes

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.

Centre for Human Rights at UFS geared to make impact in the region

After approval by the Rectorate, Senate and Council of the University of the Free State (UFS), the Free State Centre for Human Rights (FSCHR) began operations on 1 January 2016 on the Bloemfontein Campus, under the leadership of Prof Leon Wessels, founding member of the South African Human Rights Commission (SAHRC) as the Acting Director of the centre.

Human rights remain, undoubtedly, the dominant moral and political language of our times and thus demands multi-layered scholarly engagement as it influences national and international relations, and sets standards for political and democratic practice.

Establishment of centre fulfilment of court order
Top on the centre’s agenda will be to resolve the debate with the SAHRC relating to the February 2011 post-Reitz agreement of the UFS, which was subsequently made an order of the Equality Court. This order compelled the UFS to establish such a centre. The FSCHR presents new opportunities for cooperation between the FSCHR, the SAHRC and other stakeholders to the benefit of the UFS and the broader community.

Three divisions of the centre to achieve its mandate
The centre consists of three inter-related divisions with the potential to stimulate critical scholarship in the field of human rights through its postgraduate and research division. This is reflected in the centre’s mission to deepen the study of human rights and further its praxes by developing novel methodologies in which traditional human rights issues can be complemented by interdisciplinary and multi-disciplinary approaches.

The Advocacy division of the centre will promote human rights among UFS staff and students, and the surrounding community. The aim is to establish a vibrant human rights culture in and across all campuses in which rights of all are respected and protected.

The Legal Services division will provide trustworthy legal services to individuals and groups whose fundamental rights have been abused, to improve the professional capacity of paralegals, students, counsellors, social workers, candidate attorneys and attorneys, equipping them to deal with cases of infringement of constitutional and human rights and to increase access to justice to rural and indigent communities in the Free State.

Centre key in positioning UFS as a regional leader in human rights issues
The centre, with its inter- and multi-disciplinary approach, has the potential to become one of the flagship projects of the UFS, and will strengthen both the Academic and Human Projects. A UFS human rights centre not only makes sound scholarly and practical sense, it also has limitless symbolic value. The location of one of UFS’s campuses within the city of Bloemfontein (the judicial capital of South Africa) and having partnered with the National University of Lesotho (NUL), is historically and geographically significant. This has a great impact on the UFS, the Free State province as a whole, and the Kingdom of Lesotho.

The FSCHR will be officially launched on 14 March 2017 with Professor Bongani Majola, newly elected chairperson of the SAHRC, as guest speaker.
