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.

Department of English changed to empower students

A new curriculum, exciting third-year seminars, and a transition to continuous assessment. These are some of the changes made by the Department of English at the University of the Free State (UFS) over the past few years. The department, which also boasts four National Research Foundation (NRF) researchers, did this to tailor the curriculum towards the needs of its students and to foster a better culture of engagement.

According to Prof Helene Strauss, Head of the Department, the advantages of these changes are clear. “Staff have noted a significant improvement in both the basic writing and critical deliberation skills of our students, and in the responsibility they are taking for their own learning.” The new curriculum empowers students to take a position in relation to the knowledge they encounter in the classroom, thereby strengthening their own critical voice.

Taking continuous responsibility

One of the most significant changes for students was the fact that they have to take responsibility all the time. Prof Strauss says continuous assessment changed “last-minute cramming to near-daily, student-centred activities of reading, writing, and critical discovery.”

Because students have to prepare for lectures and reflect on materials, they are in a better position to internalise difficult debates and critical concepts. “Rather than telling students what to think, we help them develop flexible, critical tools to make sense of a changing world.”

Third-year seminars are another way of including forms of instruction that concentrate on the links between education and democracy, but still improve students’ ability to speak and write English accurately. Every semester, students can choose seminars from a range of topics such as ‘Witchcraft’ (Prof Margaret Raftery) and ‘The Art of Dying’ (Dr Mariza Brooks).

Research and associates around the world

Dr Marthinus Conradie, Dr Rodwell Makombe, Prof Irikidzayi Manase, and Prof Strauss are all NRF-rated researchers in the department.

The department also has affiliated research associates from countries including Zimbabwe, the USA, and Canada. Dr Kudzayi Ngara currently holds a competitive NRF grant for a project on Southern African urbanity, and Dr Philip Aghoghovwia recently received the prestigious African Humanities Programme Fellowship.

Under the guidance of Dr Ngara, the department has been able to roll out a new Honours programme on the Qwaqwa Campus. The campus now also offers students the opportunity to pursue MA and PhD studies.

Other highlights:
• Hosted the international Institute of the Association for Cultural Studies in 2015.
• Books published: Dr Susan Brokensha (with Burgert Senekal). Surfers van die Tsunami: Navorsing en Inligtingstegnologie binne die Geesteswetenskappe (SUN MeDIA, 2014); Prof Iri Manase. White Narratives: The depiction of post-2000 land invasions in Zimbabwe (UNISA Press, 2016); as well as co-edited volumes with Cambridge Scholars Publishing (Dr Oliver Nyambi) and Routledge (Prof Helene Strauss).
• Publications include three special journal issues (of ISI journals Critical Arts: South-North Cultural and Media Studies; Safundi: The Journal of South African and American Studies; Interventions: International Journal of Postcolonial Studies).
