Wilku Meyer is the co-recipient of the Junior Captain Scott Memorial Medal for Plant Sciences, awarded every second year by the South African Academy for Science and Arts for the best MSc dissertation awarded at a South African university.

In 2016, sunflower rust was very prominent, causing trouble in the agricultural industry. With the latest information on this topic published as far back as the 1990s, Wilku Meyer, PhD Botany student at the University of the Free State (UFS), saw the gap in research and decided to make sunflower rust the focus of his master’s dissertation. 

“After seeing the work researchers are doing in the Department of Plant Sciences at the UFS and how it can be applied, it was reassuring to know that the work you are doing can, in addition to broadening your own horizons, also help other people,” says Meyer. 

Not only will his research one day possibly make a positive difference in the agriculture sector, but he has also received acknowledgement for this work from the prestigious body, the South African Academy for Science and Arts

Best MSc dissertation in Plant Sciences

With his dissertation: ‘Phenotypic and genotypic variation of Puccinia helianthi in South Africa’, Meyer is the co-recipient of the Junior Captain Scott Memorial Medal for Plant Sciences, awarded every second year by the South African Academy for Science and Arts for the best MSc dissertation awarded at a South African university. Ruan van der Nest from the Stellenbosch University Department of Agronomy shared the award with him. 

The focus of his dissertation was to see how many different races of the Puccinia helianthi fungus are responsible for sunflower rust. He explains: “I followed two approaches to this, namely the phenotypic approach whereby specific sunflower lines are infected with spores of different Puccinia helianthi isolates collected from sunflower fields in South Africa. With the second approach, the genotypic approach, I looked at the DNA of collected rust samples and compared them with each other.” 

In the end, he was able to identify six races in total that were spread across four main genetic groups.

Meyer did not settle for subpar results and kept going, no matter how much work it was, or the time required. He put all his time and effort into this study. He believes that the guidance of his supervisors and the support of his family and friends also helped with this big achievement.

Hard-working, dependable, and mature researcher

Prof Botma Visser (Botany), one of Meyer’s supervisors during his master’s study, describes him as hard-working, dependable, and a mature researcher. According to Prof Visser, the one attribute that will benefit him with his PhD, is his computer skills, especially in the field of Bioinformatics. “This is becoming an important skill set for postgraduate students, whereby huge datasets generated with the newest DNA sequencing technologies are analysed to provide next-generation results and understanding the interactions between a plant and a pathogen.” 

“Finally, and maybe his best quality, is that he really loves what he is currently doing – from the practical hands-on work in the greenhouse, to the laboratory and computer-based molecular analyses of the plant pathogen,” adds Prof Visser. 

Meyer, in response to the award from the South African Academy for Science and Arts, says it is an honour. “I'm very grateful that all the time and effort is being recognised. It is a confirmation that I'm doing what I should be doing.”

He started his PhD study this year (2021), again under the supervision of Prof Botma Visser and Prof Willem Boshoff (Plant Pathology).

Inaugural lecture: World on verge of agricultural revolution
2008-05-19

A changing economic climate and new technology will see to a number of interesting changes in the livestock industry in the next few years. This is according to Prof. Frikkie Neser of the Department of Animal and Wildlife and Grassland Sciences, who delivered his inaugural lecture at the UFS on the subject: “The quest for a superior animal”.

Prof. Neser focused on the future of animal breeding in the next few decades.

He said the world, but especially South Africa, stand on the verge of a revolution in the agriculture sector. The whole production scenario will probably change. The high fuel and food prices are the two biggest factors that will play a role.

“Increasing fuel prices opened the door for the production of bio-fuel. The fuel industry is in direct competition with humans and the livestock industry for the same resource that result in unbelievable high prices for maize, sunflower and soya. These prices can further increase with the worldwide shortage of food,” he said.

More profitable breeds could take the place of existing breeds because of the big increase in input costs, he said. “Selection for more effective, and not maximum production, will became more important.

“There are also indications of pressure on feed lots. If this industry downsizes, it could lead to a total turnaround in the beef industry. The feed lots prefer a later maturing animal that can put on a lot of weight before fat is laid down. If this industry declines, early maturing breeds and some of the synthetic breeds, as well as crossbreeding with early maturing breeds, will play a more prominent role in the meat industry.

“This will also lead to a decline in the total number of animals in order to prevent overgrazing. This can result in an increase in imports from neighbouring countries and especially Brazil, where production costs are much lower.

“One way to increase the profitability of meat production is to utilise niche markets. There is world-wide a shift to more natural products. The demand for grass-fed beef drastically increased. According to research it is healthier than meat from feed lots and usually free of hormones and antibiotics. If factors such as traceability are put in place, this could be a very profitable niche mark for the South African meat industry,” he said.

Prof. Neser also said: “In order for breeding societies to survive they need to increase the number of members and the animals that are being registered. This they do by replacing the word stud with recorded animals. Hereby they open the door for excellent commercial animals to become part of the seed-stock industry. Another benefit is that especially in the smaller breeds more information becomes available, resulting in more accurate breeding values.”
