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 receives an award from the World Universities Forum
2011-01-11

The University of the Free State (UFS) has received the World Universities Forum (WUF) Award for Best Practice in Higher Education during 2010.

The Best Practice Award recognises the most significant practices of the year around the world. The UFS’s implementation of a number of interlocking innovations to transform the institution is recognised with the award.
 
These innovations include:
  • campus-wide racial integration among students;
  • the reinvigoration of the academic culture;
  • the nurturing of the most promising young scholars by means of the Vice-Chancellor's Prestige Young Scholars Programme;
  • sending 71 first-year students to top American universities to assist with their development into non-racial campus leaders;
  • the revision of the undergraduate curriculum to promote a cross-disciplinary approach to key societal problems;
  • raising the entry requirements;
  • the facilitation of open access to campus leadership through sessions with the Vice-Chancellor and Rector, Prof. Jonathan  Jansen – providing opportunities for public discussion between senior leadership, staff and students;
  • the UFS also extended this spirit of dialogue internationally through the inauguration of its International Advisory Council consisting of key thinkers and practitioners;
  • the identification of 20 of the most dysfunctional high schools in the Free State Province and the building of relationships with those schools. This university-school partnership is based on a strict contract of reciprocal commitments to increase the chances of black children attending university. The WUF applauded this as the most innovative step.
 
“We at the UFS are humbled, but encouraged by the recognition of academic excellence and institutional transformation that comes with this prestigious international award,” said Prof. Jansen.
 
The WUF said in a statement that these innovations demonstrate the profound impact higher education practices can have when they are well conceived and implemented.  “We applaud these innovations and the ways in which they promote racial harmony, student success and overall academic vitality,” the statement reads.
 
The Best Practice Award will be announced formally at this year’s World Universities Forum, which will be held at the Hong Kong Institute of Education from 14-16 January 2011. 
 
 A message of appreciation from Prof. Jansen will be read by Prof. Fazal Rizvi, Programme Convenor of the WUF 2011 during the award ceremony.
