Dr Cornel Bender
Dr Cornel Bender received her PhD qualification at the virtual graduation ceremonies in October. The title of her thesis is: Stem rust resistance in South African wheat and triticale.

The rapid distribution of disease-causing organisms such as Ug99, a wheat stem-rust pathotype, pointed out just how vulnerable global cereal production is to disease outbreaks.

These cereals include wheat, barley, rye, oats, triticale, rice, maize, and millet and are one of the most important food sources for human consumption.

According to Dr Cornel Bender, the projected world population of 10 billion in 2057 requires a growth of more than 40% in cereal production. Wheat is grown on more hectares than any other cereal and is one of the most important sources of calories for humans. However, the growth rate of wheat yields has declined from the 1960s to the 1990s. Therefore, it is essential to increase global wheat production.

“With the regular appearance of more aggressive stem rust pathotypes in South Africa, there is a constant need to discover new sources of resistance, understand the genetic base of presently deployed sources in wheat, triticale and barley cultivars, and to manipulate the deployment of resistant sources through a more sustainable approach,” says Dr Bender.

Her PhD thesis, titled: Stem rust resistance in South African wheat and triticale, includes various fundamental aspects for the effective management of stem rust in South Africa.

Dr Bender is a Professional Officer in the Division of Plant Pathology in the Department of Plant Sciences, who received her PhD at the virtual graduation ceremonies in October.

Innovative and cost effective

Her promotors, Prof Zakkie Pretorius, Research Fellow, and Dr Willem Boshoff, Senior Lecturer in the Department of Plant Sciences, believe that she used an innovative approach to develop a cost-effective phenotyping method to select for more durable resistance types in a controlled greenhouse environment.

“In the past, results obtained from field trials used to assess adult plants for stem-rust resistance, were often influenced by abiotic factors, were seasonable in nature, expensive, and time consuming; therefore, the development of a dependable greenhouse screening system provides an important additional instrument for rust research,” says Dr Bender.

She adds that the greenhouse technique is used worldwide to screen for adult plant resistance and contribute to save time and money.

Broadening our knowledge

“Inheritance studies were undertaken to determine the genetic base of stem-rust resistance in selected South African wheat and triticale cultivars (developed from wheat/rye crosses) through seedling analysis as well as greenhouse and fieldwork,” she says.

Dr Bender believes the use and development of different resistance screening methods, the elucidation of host genetics, as well as the use of histological and microscopic methods to study early resistance responses, broaden our knowledge and understanding of stem-rust resistance in South African wheat and triticale cultivars.

Ultimately, rust researchers, grain producers, and also the general public – through access to their daily bread – will benefit from her study.

Translation Day Seminar
2007-10-22

Subverting the West? Engaging language practice as African interpretation.

With the above-mentioned title in mind, about 30 people gathered at the Main Campus of the University of the Free State (FS) in Bloemfontein for a Translation Day Seminar. The day was attended by academics, language practitioners, government departments, students, and other stakeholders in language practice.

Prof. Jackie Naudé, the Programme Director for the Programme in Language Practice at the UFS, gave a short historical overview of developments in research and training in language practice of the past decade. He argued in favour of a socio-constructivist approach to teaching and research in language practice. His point was that students need to be given the opportunity to engage with the complexities of real-life problems, specifically the complexities of the African context.

Dr Kobus Marais, Senior Lecturer in Translation Studies at the UFS, gave an overview of the state of the art of translation research. This meant that language practitioners are agents in communication, not mere conduits of meaning. He argued that translators’ agency implied that they have to make informed choices, the most important of which is whether to indigenise or foreignise when translating. He developed wisdom as a notion in translation, indicating that translators need to be wise to interpret their context and translate in such a way that (Western) ideology does not ride piggy-back on their translations into the African target culture.

Prof. Joan Connoly, Associate Professor in the Centre for Higher Education Development at Durban University of Technology (DUT), took the audience on a breathtaking journey on the topic of oral knowledge. Her presentation showed examples, both European and African oral knowledge and had a clear message for language practitioners: What can Africans learn from the Western mind? Her answer: "Africans can learn how easy it is to loose one’s oral knowledge base. Africans can look at the West and see what the consequences are when a culture loses its oral-based knowledge. Language practitioners have it in their power to consider this possible loss and do something about it."

Lastly, Ms Lolie Makhubu, Head of the Department of Language and Translation at DUT, spoke about enticement in interpreting to use loan words to impress either the audience or peers or clients. Her argument boils down to the interpreter’s attitude towards African culture and language. If Western culture is regarded as higher than African culture, interpreters will be tempted to boast their knowledge of Western culture by means of their choice of words. However, if interpreters are “Proudly South African”, as she put it, they have not need for showing off by using loan words.
