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.

The first study book with the title Theology and the Post(Apartheid) Condition, which is part of a new academic series by the Faculty of Theology and Religion at the University of the Free State, is now available. Volume 1, compiled by Professor Rian Venter as editor, is the first book in the ‘UFS Theological Exploration’ academic series, which the faculty plans to release.

Transformation
Professor Venter says the transformation of processes and practices in communicating and creating knowledge has become an urgent task for public universities in a democratic South Africa. Much reflection has already gone into the methods and scope of transformation in higher education.

Although the faculty has done work on the implications of this for theology, there is one area of investigation that has not received much attention. It concerns the role of theological disciplines such as Old and New Testament, Missiology and Systematic Theology and Practical Theology, and specifically the relationship between academic disciplines and societal growth. The book focuses on these challenges and contains the intellectual undertakings of the contributors who are all lecturers, research fellows and post-graduate students linked to the faculty.

The questions
The key questions addressed are: what are the contours of the (post)apartheid condition and what are the implications for responsible discipline practices in theology. Professor Venter says the chapters in the book are logically arranged and moves from wider to more specific concerns. The first three chapters suggest broad perspectives on the challenges for theology in higher education, chart the changes, and make some suggestions for the future.

A dynamic field of study
The book states that theology has already experienced profound and radical changes over the past decade, which is known to us. All the chapters demonstrate these fundamental shifts, which have taken place in all theological sub-disciplines. Professor Venter says the contributions in the book illustrate that theology is a dynamic field of study, and is pursued with enthusiasm and commitment. Not all disciplines in theology are investigated for the book. However, the studies reflect the interests of the theologians in the Faculty of Theology at the UFS. Professor Venter hopes that the volume might stimulate further reflection of a similar nature by other theologians.

New insights
Through the ‘UFS Theological Exploration’ research series, the faculty hopes to stimulate new insights and new developments in academic progress and overall human growth. Series editor Professor Francois Tolmie says it is a fact that strong university research is necessary to achieve academic progress and advance human prospering. He says the faculty's research series will make a valuable contribution to these causes. Professor Tolmie says the ‘UFS Theological Explorations’ contains research of the highest academic standard which has been peer-reviewed to make significant educational contributions to core theological issues in South Africa and overseas.
