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.

Pansalb’s Language Rights Monitor Project launched at the UFS
2007-01-25

 

 Attending the launch of the Language Rights Monitoring Project were, from the left: Mr Edward Sambo (acting head of Pansalb), Prof Engela Pretorius (Vice-Dean of the Faculty of the Humanities at the UFS), Prof Theo du Plessis (Director: Unit for Language Management at the UFS) and Mr Vusi Ntlakana (head of the Free State provincial office of Pansalb).

 
 Pansalb’s Language Rights Monitor Project launched at the UFS
 
The Unit for Language Management at the University of the Free State (UFS), in collaboration with the Pan-South African Language Board (Pansalb), today launched the Language Rights Monitor Project on the Main Campus in Bloemfontein.
 
In accordance with the Pansalb Act of 1995, Pansalb is responsible for the promotion and protection of language rights in South Africa, and is the chief funder of the project.          
 
The Language Rights Monitor Project was initiated in 2002 for a trial period of three years, with the aim of reporting to Pansalb, on an annual basis, on language-rights issues in South Africa, as reflected mainly in the printed media.
 
Since then, three reports have already appeared, covering various aspects relating to language rights, including, inter alia, language-rights complaints, language-rights issues, language litigation, as well as research on language rights in South Africa. Profs Johan Lubbe and Theo du Plessis, as well as Dr Elbie Truter, all associated to the UFS, were responsible for the compilation of the first three reports.
 
During 2006, Pansalb decided to establish the project for an unspecified period of time at the Unit for Language Management at the UFS. It is precisely for this reason that the project is being launched. The South African Language Rights Monitor will henceforth appear annually as a prestige publication of Pansalb, compiled by staff associated with the Unit.
 
However, Pansalb has also decided to further consolidate the project, as a result of the need for a more immediate report, as well as the need to include records drawn from newspapers published in the African languages. It was therefore decided that, as from September 2006, a monthly South African Language Rights Bulletin would also be launched. 
 
Such a bulletin would provide an overview, on a monthly basis, of developments in South Africa concerning language rights, and would enable Pansalb to become more actively involved in crisis situations in which mediation is urgently needed. Two monthly bulletins have already appeared, and were favourably received by Pansalb. During the launch of the project, this bulletin was also introduced to the public for the first time.
 
With the official launch of Pansalb’s Language Rights Monitor project in the Free State, emphasis will be placed on the leading role played by this province, and more specifically by the UFS, in the development and implementation of a multilingual policy.
 
In future, more information on the situation regarding language-rights issues in South Africa will be made available from Bloemfontein, for the benefit of South Africa’s language-rights watchdog, Pansalb, but also for the benefit of other institutions involved in language-rights issues.
 
A constructive contribution will thus be rendered to the cultivation of language justice, an important element of the democratisation process in South Africa.
