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.
Government supports the UFS's transformation push

The Minister of Higher Education and Training, Dr Blade Nzimande (pictured), has lauded the University of the Free State (UFS) for the progress it has made in increasing access for black students.
However, the minister also acknowledged that the UFS has failed in some respects to make important changes.
“The continued racial segregation of the hostels is something that is unacceptable 15 years after the introduction of a democratic order and has no doubt contributed to the kinds of attitudes that led to the notorious incident at the Reitz Hostel last year,” he said.
Dr Nzimande was delivering the JN Boshoff Commemorative Lecture on the Main Campus in Bloemfontein last night.
He said the Rector and Vice-Chancellor of the UFS, Prof Jonathan Jansen, has assured him that he will speed up this issue of residence integration and that he was confident he will do so successfully with the support of the overwhelming majority of the university community.
“He has my support in his new role and he will succeed in taking the university forward decisively along the path towards greater academic excellence and to serving its students and staff, the Free State province and South Africa as a whole, including its poorest and most disadvantaged citizens,” he said.
He said the UFS is an important national asset and “not an asset for some to the exclusion of others”.
“We will play our part as the Department of Higher Education and Training to support you in pursuing transformation, but we won’t keep quiet when we see that there are things that are developing that are actually undermining the realization of the UFS as a national asset,” he said.
Despite the fact that all our universities, he said, have policies in place to combat racism and discrimination, the Soudien Report shows that there is a disconnection between policy and actual discriminatory practice at universities.
“This is a serious problem because this disjuncture is not only because of the actions of maverick individuals on the ground, but includes the universities’ leadership, including even University Councils which are guilty of making policy in order to comply with legislation but expect that policy to be ignored in practice,” he said.
The Soudien Report is a Report of the Ministerial Committee on Transformation and Social Cohesion and the Elimination of Discrimination in Public Higher Education Institutions commissioned by the Department of Education last year.
Dr Nzimande also raised the fact that universities have neglected the Further Education and Training (FET) college sector in terms of research and teaching.
“There is not enough research by the universities on the FET college sector and yet this is the sector that we are prioritizing to absorb many of our young people who can’t make it to universities,” he said.
“We want to try and fight against this notion that in order to proceed in life university is the only place. We want to turn these FET colleges into colleges of choice and universities must help us, not only to research them but also to train FET colleges lecturers.”
He also announced that he will be calling a meeting of all the chairpersons of the Institutional Forums of the universities later this month as he feels that the role and status of these forums have been “eroded”.
