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 to accredit providers of Off-Campus Accommodation to students in Bloemfontein
2017-06-30

The University of the Free State (UFS) has embarked on a process to accredit off-campus accommodation service providers in Bloemfontein who provide accommodation to its students.

“The decision to accredit off-campus accommodation service providers comes from a concern from the university management about the safety of students and the conditions under which some of our students live in off-campus accommodation. Student accommodation is a significant aspect of the success of the UFS and consequently good quality accommodation is important for each individual student to be successful in his/her studies,” says Mr Quintin Koetaan, Senior Director: Housing and Residence Affairs at the UFS.

The accreditation process entails a list of primary requirements, drafted with the cognisance of the Mangaung Metropolitan Municipality, in terms of off-campus accommodation to which private providers must adhere in order to be accredited by the university. The requirements are in line with the Policy on the Minimum Norms and Standards for Student Housing at Public Universities (Government Gazette 39238, dated 29 September 2015).

According to Koetaan, the norms and standards as set out in the policy establish the foundation and assessment criteria for such accreditation of service providers by the UFS. “It has become necessary for the UFS to have a policy on off-campus accommodation, in order to protect the rights and interests of our students and that of the university,” says Koetaan.

Some of the primary requirements for accreditation by the UFS include the number of students that may be accommodated in each room, the quality of kitchens and kitchenettes, the number of ablution facilities, the existence of common rooms and house rules, general maintenance and cleaning, compliance with  relevant national, regional, and municipal legislative requirements regulating health and safety, provision for adequate access to the facility/establishment in case of medical and/or psychological emergency assistance being required by students, and the provision for access to emergency electricity and water facilities. Off-campus private accommodation service providers must also be in possession of approved Municipal building plans of their student accommodation facilities, as well as evidence confirming their compliance with these plans.

“Landlords and agents are also advised to become more involved in their student homes and to ensure that their properties are in good condition and secure enough for students to live in,” says Koetaan.

Off-campus private accommodation service providers have until 31 July 2017 to apply for accreditation. More information and application documentation for accreditation can be obtained by sending an email to housing@ufs.ac.za
