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.
Team on the way to SIFE world cup

A team of students from the University of the Free State (UFS) has won a national competition in business skills and entrepreneurship, and will be representing South Africa at the Students in Free Enterprise (SIFE) World Cup in New York later this year.
The SIFE World Cup will be held in New York from 10 to 12 October, and will feature student teams from 40 countries.
Antonia Gumede, a UFS student, says the competition involves students developing sustainable business models based in the community, which are evaluated in terms of entrepreneurship, financial literacy, business ethics, market economics and success skills.
Gumede says the UFS entry won first prize in all five categories at this year’s national competition.
The UFS team consisted of seven students and two faculty advisers, and included a diverse group of students studying in fields such as accounting, psychology, social science and actuarial science.
The UFS won the national SIFE competition for three years in a row – 2002, 2003 and 2004. This year (2007), the UFS team emerged as the winner for the fourth time.
The Co-ordinator of Community Service in the Faculty of Economic and Management Sciences, Tessa Ndlovu, attributes the success of the team to the university’s policy of community service learning, which she says motivates students to get involved in academically grounded projects that contribute to the well-being of the community.
“The financial, academic and emotional support from the Faculty of Economic and Management Sciences, as well as the faculty’s contribution to community service learning on the campus, contributes to the success of the team,” added Ndlovu.
The UFS SIFE team has been sweeping the board nationally. They first won the competition in 2002 and went on to represent the country at the SIFE World Cup in Amsterdam (the Netherlands), where they came fourth out of 33 countries.
In the following year (2003), the SIFE UFS team was once again crowned the national champion and went on to represent South Africa internationally, coming second in Mainz, Germany.
SIFE teams spend the academic year conducting projects that specifically meet the communities’ unique needs. These efforts assist aspiring entrepreneurs, struggling business owners, low-income families and children by teaching them how to succeed in a global market economy.
“Teams have the tremendous asset of learning from business experts who serve on their Business Advisory Boards. These people not only provide mentorship and guidance to them in terms of their projects, but also introduce them to other leaders in the community and give them access to needed resources,” said Nldovu.
“It is an unparalleled feeling to know that the contribution we as students make in our communities actually matters,” added Gumede.
