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.

New guidelines to increase diversity in student residences at the UFS
2007-06-08

As from 2008, the University of the Free State (UFS) will implement new policy guidelines for student residences so as to increase diversity on the Main Campus of the UFS in Bloemfontein.

These new policy guidelines were approved by the Council of the UFS today (Friday 8 June 2007) after consultations with a range of stakeholders, especially students currently in residences, student leaders and student organisations, with inputs received from alumni and parents as well.

According to a statement by the Chairperson of the UFS Council, Judge Faan Hancke, and the Rector and Vice-Chancellor of the UFS, Prof. Frederick Fourie, the guidelines are based on an educational rationale with a definite educational objective.

“What the UFS seeks to do with these new policy guidelines, is to overcome the racial divides of the past and equip students in residences with the knowledge and skills to understand people from other cultures, appreciate other languages and to respect differences in religion but also economic background,” Judge Hancke and Prof. Fourie said in their statement.

“This will give students in UFS residences a distinct advantage over many other work seekers in South Africa, because the workplace today is a very diverse place with people of many backgrounds,” Judge Hancke and Prof. Fourie said in their statement.
They said the UFS wanted to establish a new model of residence life in which students will voluntarily embrace diversity and learn about diversity so as to add value to their educational experience in a residence.

In the late 1990s the UFS made the first attempt to integrate its residences which led to violent clashes between white and black students. A compromise agreement was reached based on freedom of association but this has over the years led to the current situation of largely white and largely black residences.

To support students during the implementation of the new policy guidelines, the management of the UFS will establish several mechanisms and programmes for students to empower them, to build their capacity and to facilitate a smooth transition to a new model of student life in the residences.

Judge Hancke and Prof. Fourie said the decision is another important milestone in the ongoing transformation of the UFS and in the provision of quality higher education for all UFS students, and that the decision had been taken in the best interests of the students.

“This is a very carefully managed transition to bring about a non-racial character to our student residences in line with the Constitution and the ethos of a democratic South Africa,” Judge Hancke and Prof. Fourie said.

How the new policy will work in practice

As from 2008, the new policy aims to bring about an important shift in the way first-years are placed in a residence. From 2008 first-year students are to be placed to achieve a minimum diversity level of 30% in each junior residence.

In senior residences a mix of approximately 50-50 will be the goal from 2008.
Residences will be responsible for placing 50% of first-years, which gives them the scope to increase diversity. The university’s accommodation service will place the other 50%. All these placements must occur in accordance with the educational rationale and the related diversity objective.

If a residence cannot reach the diversity objectives, the university will use the 50% of placements that it controls to achieve sufficient diversity in a particular residence.

Support mechanisms for students

According to Dr Ezekiel Moraka, Vice-Rector: Student Affairs, students in the residences will not be left on their own to deal with the issues of diversity. The management of the UFS has identified several important areas where the process may need support, especially in the early stages of implementation. Students and student leadership will be involved in the further design and finalisation of the implementation details.

These areas where support will be finalised are the following:

  • Providing properly trained and qualified personnel (such as live-in wardens, residence heads etc.) to supervise the implementation of the policy on a 24-hour basis;
  • Ongoing orientation workshops for all students in residences to deal with diversity in a mature way;
  • Support to deal with language issues, including interpreting services so that language rights of all students can be respected; and
  • Assistance with the review of residence governance, administrative and other procedures that have been used in residences up to now.

“There can therefore be no doubt that the management is committed to the well-supported and successful implementation of this new policy and to giving the best possible education to all our students,” Judge Hancke and Prof Fourie said.
