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.

UFS’ position on student politics
2011-09-01

The University of the Free State (UFS) welcomes politics on its campus. It especially invites students to participate in all the political activities on campus, ranging from seminars and debates on national and provincial politics, and organization within party political structures. Earlier the year, in the run-up to the Local Government Elections, a programme was run on campus with all political parties participating in public and radio debates with students on political issues.

A university must be a place for all kinds of ideas and organizations---social, cultural, religious, academic and, yes, political. The perception that the UFS has “banned” politics is simply not true, nor is it possible within a constitutional democracy.
 
The University of the Free State once again invites SASCO and any other political groupings that have not yet registered to participate in campus life, to do so as soon as possible. It is important to the UFS that all student bodies enjoy full participation in campus life, and that there exists a vibrant and exciting political life on the campus alongside academic, social, cultural and religious life.
 
The Student Representative Council (SRC) Elections at the UFS has been constituted on independent candidacy and non-party-political basis. This is a decision crafted and recommended by the Broad Student Transformation Forum, whose members are elected by students, and approved for implementation by the highest authority of the university, the Council. The decisions of the Student Forum entails that all students can nominate individuals for a variety of student leadership positions, which includes nomination for elective portfolios in the SRC elections, but also within nine sub-councils that hold ex-officio seats on the SRC.
 
The old system which restricted student leadership to representation on a party-political basis only (DA, ANC, Freedom Front Plus etc) no longer exists.
 
This decision of the Student Forum ensures that the rights of all students to directly elect their representatives are protected, and that the SRC in fact represents the student body as a whole and not particular interest groups alone. This decision enables ALL students to stand for and participate in campus politics in the SRC elections, though not on a party political ticket. In the 2011 SRC Elections, for example, SASCO members were indeed mandated by its local branch to stand as candidates for various elected positions, as did other political parties such as the DA Student Organisation, a development which the university welcomes. 
 
Most importantly, the UFS insists that all students participate in university life with respect for the rights of all students, irrespective of their social beliefs or political commitments. The UFS insists that no student or student grouping acts to disrupt campus life or insult university staff or denigrate fellow students on grounds of race, religion, language, gender, etc. This is very important to the UFS as it works to build a non-racial culture that respects our common humanity. Our students must learn that democracy and decency go hand in hand, and that part of learning at a university, is to learn to differ without resorting to a language of derision.
 
In short, the University of the Free State warmly welcomes full participation in politics, as in other spheres of student life, on all three its campuses.
