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.

First-year students encouraged to attend UFS welcoming function

2006-01-12

The University of the Free State (UFS) will host a welcoming function for all new first-year students and their parents on Saturday 14 January 2006 in the Callie Human Centre on the Main Campus in Bloemfontein.

The function starts at 11:00 and will be addressed by the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie. UFS staff will also be available to provide vital information to first-year students on academic matters.

According to Mr Vernon Collett, Registrar: Academic Student Services at the UFS, Saturday’s welcoming function can assist students and parents by providing vital information on the many high quality academic learning programmes on offer at the UFS in six faculties.

“If students and parents have this information it will make the registration process, which starts next week Tuesday 17 January 2006, much smoother,” Mr Collett said.

The UFS has split the registration process into various categories of students and Mr Collett appealed to all students to adhere to the dates and times which apply to them as a one-stop service will be available so as to avoid unnecessary delays in the registration process.

The registration of first-time entering first-year students who applied before 30 November 2005 to study at the Bloemfontein Campus will take place from Tuesday 17 January 2006 at the Callie Human Centre.

Senior undergraduate students (that is, students entering their second or later year of study) may register from 23 January 2006.

Postgraduate students, first-time entering first-year students and other students who applied for admission to the main campus after 30 November 2005 must register at the Callie Human from 2 February 2006.

Late applications will be accepted until Wednesday 25 January 2006 at the Information Centre on the Main Campus’ Thakaneng Bridge. These applications will be regarded as pending and will be processed as places become available on the programme the student has applied for,” said Mr Collett.

Vista Campus:
The Vista Campus in Bloemfontein – which was incorporated into the UFS in January 2004 – no longer accepts applications from first-year students. Such prospective students had to apply to the UFS Main Campus. Students who had been registered on the Vista campus last year must register at the Vista Campus on the same dates as applicable on the Main Campus.

Qwaqwa Campus:
At the Qwaqwa Campus of the UFS, all first-time entering first-year students must report on Thursday 19 January 2006, after which the registration of these students will take place according to a specific programme. The official welcoming functioning for new first-years at the Qwaqwa campus of the UFS will take place on Saturday 11 February 2006 at 08:00 in the Rolihlahla Mandela Hall on the Qwaqwa Campus.

Mr Collett appealed to first-year students who have applied to study at the Qwaqwa Campus and their parents to attend this function which fulfils the same role as the one held on the Bloemfontein Main Campus.

Detailed information on the dates and times of registration for the various faculties and academic learning programmes is available on the UFS website at www.uovs.ac.za. Prospective students may also call the Main Campus in Bloemfontein on (051) 401-3000 or the Qwaqwa Campus on (058) 718-5000 for more information.
