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.
UFS staff get salary adjustment of 8,5%
2010-11-03
The University of the Free State’s (UFS) management and trade unions have agreed on a general salary adjustment of 8,5% for 2011. The negotiating parties agreed that adjustments could vary proportionally from a minimum of 7,5% to a maximum of 9,5%, depending on the government subsidy and the model forecasts.
The service benefits of staff will be adjusted to 10,66% for 2011. This is according to the estimated government subsidy that will be received in 2011.
The agreement was signed on Friday, 29 October 2010 by representatives of the UFS Management and the trade unions UVPERSU and NEHAWU.
An additional once-off, non-pensionable bonus of R3 000 will also be paid to staff with their December 2010 salary payment. The bonus will be paid to all staff members who were in the employment of the university on UFS conditions of service on 31 December 2010 and who assumed duties before 1 October 2010. The bonus is payable in recognition of the role played by staff during the year to promote the UFS as a university of excellence and as confirmation of the role and effectiveness of the remuneration model.
It is the intention to pass the maximum benefit possible on to staff without exceeding the limits of financial sustainability of the institution. For this reason, the negotiating parties reaffirmed their commitment to the Multiple-year, Income-related Remuneration Improvement Model used as a framework for negotiations. The model and its applications are unique and have as a point of departure that the UFS must be and remains financially sustainable.
Agreement was reached that 2% will be allocated for growth in capacity building to ensure that provision is made for the growth of the UFS over the last few years. A further 0,16% will be allocated to structural adjustments.
The implementation date for the salary adjustment is 1 January 2011. The adjustment will be calculated on the total remuneration package.
Prof. Johan Grobbelaar, Chairperson of the UVPERSU and NEHAWU mutual forum, is very pleased with the outcome and good spirit in which the negotiations, “that were concluded in a couple of hours”, took place. The 8,5% increase for 2011 means that for the past ten years the UFS staff has received a 38% increase above inflation in effect.
“Not only is this a major achievement in that the staff is much better off, but the salaries compare well with similar institutions in the country,” says Prof. Grobbelaar.
It is also with nostalgia that the negotiations took place this year, because Prof. Grobbelaar and Prof. Niel Viljoen, Vice-Rector: Operations, both retire in 2011. Prof. Viljoen was the chairperson of the UFS Council’s negotiation team for the past ten years.
