Revolutionising wheat: Developing cultivars that maintain their quality in heat and drought

UFS PhD student and food scientist Schae-Lee Olckers’ research could contribute to a stable supply of good quality wheat and bread, even in the face of climate change.

Follow your passion in order to find your purpose. This is the mantra of food scientist and University of the Free State (UFS) PhD student Schae-Lee Olckers, whose research is set to improve wheat quality by identifying which types of wheat are better able to tolerate stress, and which proteins are most important for producing high-quality bread.

“By grasping this, it is possible to ensure that we continue to have a stable supply of good quality wheat and bread, even in the face of climate change,” says Olckers, who believes wheat is one of the most important food grains in the human diet, and one of the most important staple cereal crops in the world.

Her PhD study, ‘The influence of abiotic stress on gluten protein and baking quality in bread wheat’, under the supervision of Dr Angie van Biljon and Prof Maryke Labuschagne in the Department of Plant Sciences, and Prof Garry Osthoff in the Department of Microbiology and Biochemistry, is investigating how different levels of heat and drought stress – mostly due to climate change – affect the gluten protein composition of high-yield bread wheat.

Olckers is a food scientist at StartWell Foods (Pty) Ltd, a non-profit organisation that produces high-quality extrusion products for feeding schemes around the country. The products help to eliminate stunted growth among children.

Her research focuses on examining different types of wheat and investigating how proteins are affected by stressors like heat and drought, to understand how these stressors impact the quality of bread. She uses new proteomic methods to look at the different proteins in the wheat flour, to gain a better appreciation of how gluten proteins react to stress.

In this study Olckers is able to see how the proteins change in the various wheat cultivars, helping us to understand how the different types of wheat perform in baking, and how the proteins affect the final product.

She collaborates with the International Maize and Wheat Improvement Center (CIMMYT) in Mexico, that releases new wheat cultivars for developing countries. Their aim is to develop wheat cultivars that maintain their quality in different environments. To investigate the performance and characteristics of the seeds, both in the field and in the laboratory, CIMMYT did the field trials, quality assessment, and supplied the seeds for high-performance liquid chromatography (HPLC) and proteomics analysis.

Finding ways to adapt to climate change

She believes that understanding how these stressors impact the production of bread-baking quality in wheat will help scientists gain important insights into how climate change affects our food supply.

“Taking into consideration the current and projected intensifying heat and water deficit stresses, it is crucial to improve the understanding of these phenomena in order to implement new breeding strategies for sustainable wheat quality. This research could help us find ways to adapt to climate change and continue to produce high-quality wheat and bread for people around the world,” Olckers says.

UFS shines in MBA survey
According to a recent survey published in the Financial Mail, the MBA programme presented by the School of Management at the University of the Free State (UFS) was rated jointly second best in the country by its graduates in terms of quality and standard.
The UFS MBA Programme was also rated fourth best by its graduates in terms of relevance to their business.

“I am overwhelmed and very proud that the School of Management, although we are a young school and have only been in existence for 7 (seven) years, has been rated so high by our graduandi. The School contributes in a very special way to much-needed business training in central South Africa,” said Prof Helena van Zyl, Director of the UFS School of Management.

“According to the survey, we have the lowest acceptance rate of applicants for the MBA programme, with only 33 students being accepted out of every 100 who apply. In general, we do not compromise on quality – as stated by our slogan: Be worth more. Given the quality of the programme, our MBA is very affordable – it offers real value for money,” said Prof van Zyl.

According to Prof van Zyl, the School of Management has had an increase the past 6 (six) months in enquiries from prospective students from Gauteng who are interested in studying the MBA programme. “They are even prepared to travel to Bloemfontein to attend classes,” she said.

This year Financial Mail moved away from an overall MBA ranking to a detailed consideration of subject area strengths for each business school in South Africa. The subject Strategy offered at the UFS School of Management was rated second in the country while the subject Economics also received the same rating.

“The School of Management is the flagship of the Faculty of Economic and Management Sciences. It gives the UFS and this faculty a standing in corporate South Africa. This is largely due to Prof Helena van Zyl’s strategy to position the school and making it visible on a national level,” said Prof Tienie Crous, Dean: Faculty of Economic and Management Sciences at the UFS.

According to Prof Crous, the UFS School of Management provides students with opportunities to obtain first-hand experience of how big and successful companies are managed. “For instance, our MBA students undertake an overseas study tour every year. This year they visited amongst others the headquarters of Airbus in Toulouse, France and next year they will be visiting the headquarters of Toyota and Yamaha in Japan,” said Prof Crous.
