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.

Always good to be honoured at home, says Justice Richard Goldstone

The University of the Free State (UFS) is determined to make a success of its academic and human projects, and is not prepared to compromise on standards in the process.

This was the message of Prof. Jonathan Jansen, Vice-Chancellor and Rector, at our universities official opening on Friday 3 February 2012. These projects, said Prof. Jansen, are the foundation of the institution.

The official opening coincided with an honorary doctorate in Law conferred on Justice Richard Goldstone.

The UFS has enrolled the “smartest and most diverse class since 1904,” Prof. Jansen said.
Top learners with six A’s, and more learners from top schools inside and outside South Africa, have made the UFS their university of choice. “We are determined that the best students must study at Kovsies.”

Prof. Jansen also referred to learners in the school system who sit and wait while teachers fight amongst themselves at the education departments. “What are we going to do with those students?” The UFS provides an opportunity for these students to enter higher education with its University Preparation Programme on its South Campus in Bloemfontein. “The fastest growth at our university is on this campus. It is set aside for children who cannot be taken up in the mainstream.”

Some of the students who were part of this programme are doctors, lawyers and teachers today.

“We set a high standard in our academic project to make sure our students are the best available.”

In its Schools Project, the UFS has 23 schools under its wing and the net is broadening. Pass rates in these schools improved dramatically; in some from 13% to 100% in one year.

The human project sets standards for good behaviour. “I was astounded to see how young people get together to find other people as human beings,” Jansen said. “I have enormous hope for this country.

Some of the other projects he mentioned were the provision of more space for students to study, a refocus on the Qwaqwa Campus in the Eastern Free State, the placement of new academics, and agreements with universities abroad on the placement of young scholars.

After receiving his honorary doctorate, Justice Goldstone congratulated the university on the fact that transformation did not lead to standards being compromised.

“The university now takes its place as a leading university on our continent. The leaders of the university can hold their heads up high about their achievements.”

Judge Goldstone, the bearer of 26 honorary doctorates from various countries around the world, said: “It is always good to be honored at home”.

The official opening was attended by staff, students, guests and community leaders.
