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.

Call for campus review and participation into renaming and renewal of statues, signs, and symbols on UFS campuses

2016-08-25

The leadership of the University of the Free State (UFS) is issuing a Call for the renaming and renewal of statues, signs, and symbols on the three campuses to staff, students, and alumni.

In line with the founding statement and guidelines of the Naming Committee of Council, The Call will seek to retain the best representations of the history and identity of the UFS over more than a century, while committing to the transformation imperatives of our new democracy so that the totality of statues, signs, and symbols give credence to both the past and the future, all in line with the values of the Constitution of the Republic of South Africa.

Submissions should be made to the
SSSC between 21 July 2016 and 31 August 2016.
Proposals can be delivered to the
office of the Director: Communication and
Brand Management at Room 49,
Main Building, Bloemfontein Campus, or
via email to sssc@ufs.ac.za.

The ‘Guiding Principles’ of the Naming Committee, approved by Council on 8 March 2013, are transformation, reconciliation, excellence, distinctiveness, leadership, comprehensiveness, balance and sensitivity. The Policy of the UFS on Naming and Renaming is available here: http://bit.ly/2aeTLUz; and the Remit of the Naming Committee of the UFS is available here: http://bit.ly/29NXESC.

The Call will give special attention to creative submissions from staff, students, and alumni, such as signs and symbols that reflect our entangled past and place rival memories in critical conversation. Whatever is proposed, our commitment to the Academic Project and the Human Project remain foundations on which inspirational proposals could be based. In the end, a campus that is richly diverse, inclusive, and just in its symbolic infrastructure, would give visible meaning to the university’s commitment to social justice and reconciliation.

All submissions should be made to the Statues, Signs, and Symbols Committee (SSSC) between 21 July 2016 and 31 August 2016. Proposals could be delivered in hard copy to the office of the Director: Communication and Brand Management at Room 49, Main Building, Bloemfontein Campus or via email to sssc@ufs.ac.za.

Proposals will be reviewed by the SSSC, which is a subcommittee of the Naming Committee.

Final proposals will be submitted to Council for consideration at its final meeting of the 2016 academic year. In other words, new statues, symbols and signs – those approved by Council – will be implemented from January 2017.

Submissions could include, but are not limited to, the following: the renaming of streets and buildings; the proposal of new statues and other symbols on campus; the renewal of artwork collections; the reconfiguration of existing statues and symbols; the introduction of memorial gardens; the instatement of new galleries, sculptures, and literary collections; the establishment of prominent academic chairs or annual academic lectures in the name of illustrious figures, etc. Particular attention should be given to new buildings in the process of being built, such as residences.

Finally, it is important that the views and recommendations of all staff, students, and alumni be considered in submissions and that every campus citizen, past and present, has a sense of being able to participate fully and freely in the process.
