Prof Liezel Herselman Inuagural Lecture
At the inaugural lecture were from the left: Prof Danie Vermeulen, Dean of the Faculty of Natural and Agricultural Sciences, Prof Liezel Herselman, Dr Adré Minnaar-Ontong, Senior Lecturer in the Department of Plant Sciences and Subject Head of Plant Breeding, and Dr Molapo Qhobela, Vice-Rector: Institutional Change, Strategic Partnerships and Societal Impact.

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.

Chief Justice Mogoeng Mogoeng yesterday (24 January 2013) concluded the proceedings of the first day of the International Symposium on Corruption, hosted by the Faculty of Law of the University of the Free State (UFS). In his address Justice Mogoeng made no excuses as to the magnitude of the threat corruption presents to South African citizens.

“Urgent action and efficient measures are called for to arrest this scourge, for the sake of our constitutional democracy,” he warned. “Our vibrant constitutional democracy will not and cannot survive in the face of rampant corruption.”

Justice Mogoeng said the spate of civil and labour unrest erupting throughout the country can be attributed to corruption. According to him the scope and far-reaching implications of corruption drives South Africans to “boiling point” and evokes “anger, frustration and a don’t-care-attitude that often manifests in widespread protest actions” and disrespect for the rule of law.

“South Africans, irrespective of race or creed, must identify and focus on their common enemies and find a conciliatory and unifying way of dealing with what divides them, including the lingering prejudices of the past,” Justice Mogoeng urged.

Despite the threat corruption poses, he stressed that all South Africans have a role to play in the fight against corruption and that there are different role players that can become involved in the process. Especially important is the media and faith-based agencies which, according to Justice Mogoeng, can regenerate morals and secure a “national moral code.” The State must further ensure enforcement of anti-corruption measures and preside over the selection of individuals of “solid character” to reside in agencies meant to fight corruption.

He highlighted the need for an unbiased and independent judiciary, one immune to outside influences controlled by powerful forces, as well as personal agendas.

Although Justice Mogoeng believes that the private sector is most guilty of transgressions based on corruption, he stated that a “well-coordinated war” against it must be waged in all sectors in order to stamp it out.

Justice Mogoeng presided over the unveiling of the redesigned foyer of the CR Swart Building and praised the Faculty of Law for its innovation with regard to the symposium.

“I look forward with great optimism to more well-organised symposiums that strike at the nerve-centre of the well-being of our constitutional democracy,” he concluded.

Symposium seeks answers and solutions

The Faculty of Law at the University of the Free State (UFS) concluded its International Symposium on Corruption on Friday 25 January 2013. The event featured a stellar cast of speakers, including the Chief Justice of South Africa, three current Supreme Court of Appeal judges, high-court judges, advocates, prosecutors, journalists, as well as local and international legal academics.

Throughout the two-day symposium, corruption was dissected as a severe problem in the South African socio-economic landscape and solutions were sought to alleviate the pressing concern.

The main attractions of the symposium were undoubtedly the attendance and presentations delivered by Chief Justice Mogoeng Mogoeng, as well as Prof. Leon Wessels. Prof. Wessels was described as “one of the founding fathers of the constitution of South Africa” by Judge Fritz Brand, a current Appeal Court judge and the third-longest serving judge in the country.

“Corruption is stealing the constitutional dream of this country. Corrupt leaders are fearless, those who expose corruption, are fearful,” Prof. Wessels warned.

Judge Brand closely trails the second longest serving judge in the country in former Kovsie, as well as former UFS Council Chairman, Judge Faan Hancke. Both judges addressed the symposium and chaired sessions, along with Prof. Johan Henning, Dean of the Faculty of Law, and Judge Ian van der Merwe, Chairman of the UFS Council.

It was, however, not all doom and gloom, as several of the speakers offered tangible ideas in what was often termed the “war on corruption”. Celebrated Sunday Times journalist Mzilikazi wa Afrika who has been arrested following the police leasing scandal which he exposed, urged South Africans to stand together in their fight against corruption, before it is too late.

People on the front lines in the day to day fight against corruption also spoke at the symposium, giving the audience a better understanding of the intricacies and challenges involved in the process. The Head of the National Prosecuting Authority’s Asset Forfeiture Unit, Mr Willie Hofmeyer, as well as Advocate Xolisile Khanyile, who is the Director of Public Prosecutions in the Free State, elucidated this struggle.

The symposium also hosted Prof. Chizu Makajima, a celebrated academic from the United Kingdom.

The two-day symposium ended in style as the delegates gathered in the Centenary Hall on the Bloemfontein Campus for lunch, with a further address by Prof. Leon Wessels
