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.

Dr Oprah Winfrey praises our university

“I came 8 000 miles to say, thank you, Vrystaat!” and “God bless South Africa,” were the words Dr Oprah Winfrey used yesterday to respectively open and close her address to an overflowing Callie Human Centre on our Bloemfontein Campus.

Our university awarded an honorary doctorate in Education to Dr Winfrey during a stately, yet warm and cheerful affair yesterday, which saw the 4 500 seater Callie Human Centre packed to the rafters with adoring fans, staff members and students. 

The honorary doctorate is in recognition of her unparalleled dedication to improving the lives and futures of so many by improving education and ensuring that it is accessible to all. Through her award-winning show, The Oprah Winfrey Show (which concluded this year after 25 years of entertainment and service), and the various charity organisations she has established, Dr Winfrey has harnessed the power of her iconic stature in the struggle to eradicate poverty and make education accessible to all.

The ceremony’s audience was entertained by South African music legend, Ms Sibongile Khumalo, the Bloemfontein Children’s Choir, Bartimea School for the Deaf and Blind’s Sign Language Choir, and several other musical performers as well as dancers.

Dr Winfrey could not hold back her tears when Mr John Samuel, interim Director of our International Institute for Studies in Race, Reconciliation and Social Justice, described her as an “honorary daughter of South Africa”. She proved just how much the country means to her when she joined in the singing of the South African national anthem, Nkosi Sikeleli, despite struggling with the words in some parts.

According to Dr Winfrey, her interest in our university began after she had read an article by Prof. Jonathan Jansen, Vice-Chancellor and Rector, in which he emphasised the need for South Africans to stop accepting mediocrity, if ever the country is to develop to its full potential.

She asked Mr Samuel to convey her message of support to Prof. Jansen and the wheels, which led to today’s great event, were set in motion. 

She also expressed her admiration of the transformation process at our university and our commitment to “reconciliation, peace and harmony”. “What has happened at the University of the Free State is nothing short of a miracle and this is truly what the New South Africa is about,” she said to loud cheers from the audience. 

To emphasise her point, she called the five workers from the Reitz video to the stage and used their forgiveness and acceptance of the students responsible for the video as an example of the healing achieved at the UFS. 

“Having seen this forgiveness has allowed me to expand my vision of what we can be.” She also delivered a message of encouragement and reminded students that anyone, despite their circumstances and background, could become successful and grow to overcome their obstacles, as she had done.

“Anyone can be successful if they put their mind to it, work hard and are diligent,” she said. “We must all strive for more than success, though, and fulfil the highest expression of ourselves as humans by realising who you are and what you are meant to be.”

Following her address, Dr Winfrey answered several questions from our students, giving them advice on, among other things, how to choose a career that is right for them, and good characteristics to look for in leaders and peers.

She also mentioned that several learners from the Oprah Winfrey Leadership Academy, which has its very first group of Grade 12 learners this year, would be visiting our university next month in order to help them select a university to attend next year.
