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.

“I am one step closer to entering the corporate world as a young woman. My dream is to work for a large firm and now it is possible,” said Melody Motaung, a B Accounting first-year student. She is one of the first recipients of the Old Mutual Investment Group’s Imfundo Trust scholarship, which was launched at the university recently.

Melody is one of seven Kovsies and 91 students countrywide to benefit from the R20 million trust, aimed at empowering black professional people in the financial sector. Kovsies is now one of eight universities whose students benefit from the trust. It already empowers students from the University of Johannesburg, UNISA, Nelson Mandela Metropolitan University, University of the Western Cape, University of Fort Hare, Stellenbosch University and Rhodes University.

”The UFS embodies the excellence and innovation we are looking for in tertiary institutions,“ Mr Muhammad Brey, trustee of the trust, said during the launch. He conveyed that the main aim of the trust is to address the shortage of black professional investors in South Africa and to expand the source of suitably qualified individuals in the asset management industry.

The seven recipients, all of them female first-year students, were encouraged by the speakers to do their part in addressing South Africa’s skills shortage in the financial sector.

Prof Hendri Kroukamp, Dean of the Faculty of Economic and Management Sciences, said with the assistance of the Old Mutual Investment Group, the students – four of them B Accounting students – will help to address the shortage of chartered accountants in the country. “As qualified financial experts, they can make a big contribution.”
