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 University of the Free State (UFS) together withKagiso Trust, presented the first Beyers Naudé lecture for 2012 on its South Campus in Bloemfontein last week. Speakers like Dr Wilmot James, Member of Parliament, Mr Johann Naudé, son of Dr Beyers Naudé, Mr Sipho Hlongwane, writer and columnist for the Daily Maverick and Ms Bontle Senne, Managing Director for the PUKU Children’s Literature Foundation, all gave a lecture around this year’s theme: Collaborative partnerships for social cohesion: Building a nation with ethics.

Dr Beyers Naudé played a major role in the formation of Kagiso Trust. His contribution to the trust and the fight against oppression in South Africa, as well as his challenging of the establishment from which he came, makes him one of South Africa’s courageous heroes. Kagiso Trust thus saw it fit to celebrate the life of this clerical activist through a Memorial Lecture The Beyers Naudé Memorial Lecture is an effort by the Trust to engage South Africans into a dialogue about issues affecting our nation.

Mr Johann Naudé talked about the lessons they as children learnt from their parents as well as his father’s decision to respond to the needs of the people in South Africa. Even before the Sharpeville Massacre, Dr Naudé began a self-transformation that led to his rejection of apartheid. “Apartheid had no theological or scriptural grounds and my father decided to resign from the church. After that, he started to talk openly against apartheid and he also paid the price for that. For seven years he was under house arrest and we as his children also felt the effect of his decision. At the University of Pretoria in a residence where I stayed as a student I was called in and told that I would be treated as an outcast. Loans and jobs were also closed for us as children and as a result, we all started our own businesses,” Mr Naudé said.

“Furthermore, our parents taught us to believe in ourselves. He also said we have rights and we can only demand those rights if we take the responsibility that goes with it. My father also taught us to honour and to respect our fellow men, elderly people and the culture of people different from us. We were also taught to apologise for the wrongs to our fellow men and to acknowledge earnestly that we were wrong.”

Dr Wilmot James said that there were two things consistent in the life of Dr Beyers Naudé, namely justice and fairness. “There are many Nelson Mandelas and Beyers Naudés out there. It is the responsibility of political parties and institutions to motivate such leadership. We must ask ourselves: Are my actions and decisions ethical and will they have fair consequences?” Dr James said.

Mr Hlongwane focused his presentation on the ethics part of the theme. He said: “We in South Africa fall very short of ethics. We can start by respecting each other and taking care of one another. The Constitution will not mean a thing if we fail to respect and trust one another. We will have no cohesive society if we continue to treat those different from us like dirt. It is also our ethical duty to build up the disadvantaged.

In her discussion, Ms Senne emphasised the role of the youth in South Africa. “Our youth is failing our state because our state is failing our youth. Their role is to bring cohesion and acts of courageousness to the table. For them to contribute in a practical and sustainable manner, they need to start making the changes they want to see in society. They are young people and they can make it work because they do have access to the necessary means (social networks) to get things done. They must get involved,” she said.
