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.

2011 Leadership group meets for the first time
2011-08-01

The long application process, panel interviews and nail-biting wait finally came to an end the past week, when the cream of our first-year class of 2011 gathered in the Scaena Theatre on our Bloemfontein Campus, for their first group meeting as the selected Leadership for Change cohort.

These 150 students, from all our faculties, will over the following year be groomed to be leaders, not only at the university, but also in their respective fields and chosen careers.
The first group of students will depart for their respective universities in America and Europe on 22 September 2011, where they will spend two weeks. The second group of students will depart for universities in Japan in January 2012.

Although they have all passed a gruelling selection process, the real hard work is only starting now for these bright young students.

The programme will take place in four phases. During the preparation phase, which has now kicked off, students are prepared for the experience ahead, while being made aware of exactly what to expect from the programme.

In the study-abroad phase, students will be placed at 15 partner institutions in various countries, and will be divided into groups of six to twelve people. According to Prof. Aldo Stroebel, Director of International Academic Programmes, the groups will be diverse, in that there will be a mix of races, genders and study fields, which should guarantee dynamic interaction.

During the group’s first meeting this week, they were informed of the important goals of the Leadership for Change Programme, by Mr Rudi Buys, Dean of Student Affairs.

He imparted the gravity of their selection on the students by saying, “You may not get it yet, but I understand the reason we are all here. I understand that by looking at what you achieve after this programme, we can tell what the country could possibly achieve in the future. It is immensely moving to see the way you all carry yourselves, since I can see something special and unique in each of you.”
“You are all here, not because of which school you went to, or your race, or who your parents are, but because you all show potential to be something great.”

Prof. Stroebel reminded the group that despite the excitement that they all have about visiting universities in America, Europe and Asia, these visits should be seen as study trips.

“You may have three days to acquaint yourselves with the surroundings, but after that there will be very little sightseeing and a lot of hard work.”

They will participate in programmes designed by their respective host institutions, aimed at exposing them to different cultures, lifestyles and beliefs.

They will be accompanied by our staff, who Prof. Stroebel says will grow with the students, as they will be expected to guide the students through their tasks and assignments and interact with them on a daily basis.

Upon their return, there will be a debriefing phase, during which they will be expected to provide feedback on their experiences, as well as submit assignments which they will be assigned at their respective institutions.

The final phase is known as the impact phase, as this will see the students apply what they have learned in a positive manner and help drive the university to the future and to becoming a world-leading tertiary institution.
