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 implements paperless meeting system
2004-08-20

 

The Management Committee of the University of the Free State ’s (UFS) Executive Management recently entered the electronic environment of more effective and centralised meeting and decision-making administration by implementing ‘n computerised meeting system.

With this the UFS became the first higher education institution in the world to use the PARNASSUS-meeting management system. PARNASSUS , which refers to a mountain in the Greek mythology, is a licensed system from CIPAL in Belguim – a developer of software for a variety of applications.

“In stead of coming to a weekly management meeting with a file of documentation, each member now walks in with his/her laptop and the whole meeting procedure takes place electronically,” says Prof Sakkie Steyn, Registrar: General at the UFS.

At the same time the secretary registers the minutes point by point on the PARNASSUS programme. At the end of the meeting, after certain technical finishes are done, the minutes are distributed to members of the meeting and their secretaries/office managers. The draft minutes is also distributed to those who must implement decisions and prepare implementation steps. These staff members are given security clearance beforehand.

“The system is unique due to the fact that a translation engine has been built into the agenda and minute system. Agenda items can be submitted in Afrikaans and then automatically be translated in English by means of the interactive translation engine, or vice versa. The same principle applies to the minutes,” says Prof Steyn.

According to Prof Steyn the translation engine was develop with the expert assistance of the UFS’s Unit for Language Facilitation and Empowerment (ULFE). Word strings from previous minutes are now being added to the corpus of the translation engine.

“The system enables the secretary to continuously monitor which points are submitted for the agenda and if these points comply with the set standards namely clear recommendations, background and proposed implementation steps. The agenda is closed at a certain moment and no new points can then be added. The secretary does certain technical finished by means of a final classification of point and annexures. The draft agenda is then sent to the chairperson for approval, after which the agenda is electronically sent to members of the meeting and their secretaries/office managers for preparation,” says Prof Steyn.

“After the minutes have been approved at the next meeting, it is saved on the PARNASSUS decisions data base. The tracing of decisions made during previous meetings can be done by any person with the necessary security clearance. This is different from the past where stacks of documents had to be searched to find a decision,” says Prof Steyn.

According to Prof Steyn the secretariat and meeting administration services at the UFS has now entered a fully virtual and electronic environment. This will enhance effective decision making tremendously. “The PARNASSUS system saves us costs and time and the decentralisation of submissions to meetings lessens the work at centralised points,” says Prof Steyn.
