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.

UFS Council unanimously approves two senior appointments
2014-11-24

The Council of the University of the Free State (UFS) unanimously approved the appointment of Dr Lis Lange as Vice-Rector: Academic and Prof Sechaba Mahlomaholo as Dean: Education during its meeting on Friday 21 November 2014.

Dr Lis Lange is currently Acting Vice-Rector: Academic at the University of the Free State, where she holds a substantive position as Senior Director heading the Directorate for Institutional Research and Academic Planning (DIRAP). Prof Mahlomaholo is Head of the School of Mathematics, Natural Sciences and Technology Education at the UFS.

“These are two exceptional and trusted academics with international stature and I am delighted to welcome them as part of the senior leadership of the UFS. Dr Lange’s skills set pertaining to academic management and quality assurance make her one of only a few people with similar skills in the country, while Prof Mahlomaholo is a leading expert in community-based education,” says Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

Dr Lange joined the UFS in 2011. Before this, she was the Executive Director (2006-2010) of the Higher Education Quality Committee of the Council of Higher Education (CHE), and Acting CEO of the same organisation between August 2007 and April 2008. She has been involved in the development and implementation of science and technology and higher education policy in South Africa for a decade and a half, working in different capacities in the Human Sciences Research Council, the National Research Foundation and the Council on Higher Education. Dr Lange has served as a member of the board of the International Network of Quality Assurance Agencies in Higher Education (INQAAHE) and has participated in several international initiatives on quality assurance. She is the editor of an academic journal focused on the humanities, Acta Academica.

She has undertaken research and published in the fields of history, higher education and quality assurance. Her major concern in both research and practice is the role of higher education in the development of democratic societies, based on social justice. Dr Lange studied in Argentina, Mexico and South Africa, where she obtained a PhD in South African history from the University of the Witwatersrand.

Prof Mahlomaholo is a graduate of the Universities of the North, Western Cape and Harvard University in the United States. He is a National Research Foundation (NRF)-rated Professor of Education.

Before joining the UFS, he worked at six other universities where he was Deputy Dean in the Faculty of Education (UNIN-QwaQwa), Head of Professional Education (Vista University), Professor and Director of Research and Postgraduate Studies (MEDUNSA), Professor and Director of Curriculum Development (Central University of Technology), and Research Professor (North-West University).

His research interests lie in designing strategies mounted on Bricolage, Participatory Action Research and Critical Emancipatory Research as theoretical bases. He leads the NRF-sponsored project on the creation of Sustainable Learning Environments in schools. In this Participatory Action Research project, 28 PhD and 22 MEd students participate under the guidance of 15 academics. The project has relationships with the Global Network project (St Petersburg University), the Post-Colonial Education project (West Indies University) and the Discourse, Power, Resistance project (Plymouth University and now University of London). He has served as guest editor in the following ISI-indexed, peer-reviewed and accredited journals: the South African Journal of Higher Education (2010 and 2014), the South African Journal of Education (2011), Communitas (2012), the Journal of New Generation Sciences (2012), the Journal for Transdisciplinary Research in Southern Africa (2013) and the Journal of Education Studies (2013).
