Prof Liezel Herselman, Academic Head of the Department of Plant Sciences at the University of the Free State (UFS),) delivered her inaugural lecture on the Bloemfontein Campus this week (24 March 2022). The theme of the lecture was the ongoing battle against destructive cereal killers. 

With 28 years of extensive experience as a researcher, her work focuses on marker-assisted disease resistance breeding in wheat within a South African context. When she joined the UFS in 2004, Prof Herselman decided to apply her research expertise in marker-assisted breeding to the problems faced by wheat producers in the Free State and Northern Cape. The Free State is one of the major dryland wheat production areas in South Africa, while irrigation wheat is produced along the major rivers in the Northern Cape. 

Protection against fungal diseases

Concentrating specifically on Fusarium head blight (or wheat scab) and three rust diseases – leaf rust, stem rust, and stripe rust – she has done work to provide wheat plants with ‘tools’ to protect themselves against these fungal diseases.

According to Prof Herselman, there are many genes available in different wheat genotypes and related grass species that provide excellent protection against various races of these diseases. “Some of these genes provide protection or resistance from the seedling stage, while others provide resistance at the adult plant stage. We are thus aiming to combine as many of these genes as possible into a single wheat cultivar, without compromising yield and bread-making quality.”

She says the genes are combined by making crosses between resistant and susceptible cultivars or lines. Conventionally, through a time-consuming process, the incorporation of these genes is tested in the greenhouse and field by infecting plants with the disease to see which plants are resistant and which are not.

They can, however, follow the transfer of these genes to newly developed lines by applying molecular markers. Prof Herselman explains: “A molecular marker is a genomic fragment linked to the gene, which we can follow in the offspring we create from the crosses using different DNA techniques in the laboratory. This enables us to select new wheat lines that contain the highest number of resistance genes. The identified best lines are then used in further crosses and/or released as pre-breeding lines to commercial wheat breeding companies.”

Impact on food security

Her research has an impact on society by providing food security to both commercial and small-scale producers, as well as the end users of wheat (people buying bread and other wheat products). As researcher, it is also important for her to send out students to the workplace who can continue with this task in future.

Prof Herselman believes that when cultivars with fungal-disease tolerance or resistance are released and used by producers, it not only reduces the cost of spraying against diseases, but also increases yields by protecting the crop against fungal diseases. “We live in a world where the population is increasing daily, but land available for agriculture is not increasing and some areas are even lost due to urban development. Increasing yield in available production areas will thus have a positive impact on food security,” she says.

Besides contributing to the country’s food security, she takes pleasure in every aspect of her work. Although she misses the hands-on part of the work as academic head of the department and getting her hands dirty, she still enjoys managing the different research projects (from the conceptualisation phase to data analysis and publishing of results). The part she loves the most is to see the growth in her postgraduate students – from the moment they enter the laboratory for the first time until the day they walk out of the laboratory with their degrees. 

“It adds purpose to my life knowing that I have made a difference in a student’s life and equipped him or her with the necessary tools to be successful in the marketplace. Being able to share your knowledge is a gift, but with that gift comes a lot of responsibility as well. I am, however, up for the challenge,” concludes Prof Herselman.

Alumni inspired to keep flying the Kovsie flag high at reunion weekend festivities
2015-09-01

Dr Khotso Mokhele and Adv Roelf Meyer

The University of the Free State hosted alumni from all over the country on the Bloemfontein Campus during a weekend of exciting events, talks, and tours around the campus on 28 and 29 August 2015.

The celebratory events were kick-started with a leadership symposium hosted by Dr Marcus Ingram, Director: Institutional Advancement with Adv Roelf Meyer. The symposium was attended by current student leaders and the SRC Presidents Alumni Association. In his dialogue with the audience, Adv Meyer shared his experiences and personal growth in the process of bringing about democracy in the country with student leaders as change agents. “If you really want to contribute to change, it is not only an intellectual exercise; it is also a heart and soul thing,” he said.

The anchor event was the inaugural Chancellor’s Distinguished Alumnus Award Luncheon hosted by Chancellor, Dr Khotso Mokhele. Prof Jonathan Jansen, Vice-Chancellor and Rector, welcomed guests by highlighting the latest extraordinary achievements of UFS students and academic staff.

Keynote speaker of the day, Ms Nozizwe Madlala-Routledge, Executive Director of Inyathelo and a renowned politician, spoke of the role that universities have in preparing women for leadership roles and how they, in turn, can prepare society for female leadership.  She commended the UFS’s advancement efforts supported by the Kresge Foundation, which supports young people, to keep them in universities. “I am proud to say that the UFS’s efforts in advancement have achieved its goals.”

In his remarks, Dr Mokhele said “what draws a student back to his/her Alma Mater is the quality of the experience they had on campus.  This campus contributed to the transformation of this country through alumni such as Roelf Meyer and Kobie Coetsee.”  He said this initiative should create a lived experience for students on the university campus.  The Chancellor presented the Distinguished Alumnus Award to Adv Roelf Meyer, for his outstanding contributions to the human interests of South Africa, and his current work of facilitating peace processes around the world.

In accepting the award, Adv Meyer introduced Youth Zones, a project which he has been involved with for the past five years, empowering and supporting 40,000 youths in the Free State. In accepting the award, he said “I was a first-year student in 1960, my year group represented the most emphatic group of this university. There are many who came before and after us who well deserve this award, therefore, I accept it on behalf of all alumni.”

To wrap up the weekend’s festivities, former SRC President, Richard Chemaly, hosted the Faculty of Law alumni cocktail event at the CR Swart Auditorium.
Speaking at the event, Prof Caroline Nicholson, Dean of the Faculty of Law, said “A faculty cannot exist without its alumni, we need you to carry us.  Your continued support and collaboration is truly appreciated.”

Alumni and staff enjoyed further entertainment by well-known musical groups, Freshly-Ground and The Muses.
