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.

Moshoeshoe's legacy lives on in university's project: City Press - 2 May 2004

Moshoeshoe's legacy lives on in university's project

MATEFU MOKOENA

DRUMS were beaten and the sounds of traditional songs reverberated through corridors of the University of the Free State (UFS) as Basotho students gathered at the campus over the weekend to launch a project honouring their late great king, Moshoeshoe.

The launch was organised by the Lesotho Students Association and UFS management and was blessed by King Letsie III of Lesotho.

According to UFS rector and vicechancellor, Professor Frederick Fourie, the aim of the project is to make the legacy of Moshoeshoe a living part of the university.

He said the Moshoeshoe project will include a television documentary on his life as well as an anthology of creative writings, including prose and poetry, about him.

A television documentary is already being filmed and will be screened during an international conference at UFS in October.

Fourie said the university, as part of the project, is looking at the possibility of starting an annual Moshoeshoe memorial lecture that will focus on African leadership, nationbuilding and reconciliation.

He said the university would introduce a PhD-level research course into the life and legacy of Moshoeshoe.

The university management has also taken a decision to erect a statue of Moshoeshoe on the campus.

Fourie said the project was launched after the UFS delegation, led by him, met Letsie III.

"He wanted us to ensure the legacy of Moshoeshoe is honoured and treated with the respect he deserves."

His legacy "must live on -- not only for the Basotho, but for all South Africans, black and white, and for the entire African continent", he said.

"Living out such a legacy is indeed a fitting contribution to the New Partnership for Africa's Development (Nepad) and to the maturing democracy that is being built here in South Africa," said Fourie.

He emphasised Moshoeshoe was and remains a model of African leadership.

Fourie said Moshoeshoe's diplomacy and commitment to peace put him on a par with former president Nelson Mandela as a statesman.

It is Fourie's dream that, through this project, the UFS will be able to give real meaning to words such as reconciliation, respect for the diversity of languages and cultures and the unity that is needed to build a democratic nation.

The Lesotho Students Association secretary, Sofonea Shale, said for an institution like the UFS to honour Moshoeshoe demonstrates that he was a great leader. "For Basotho students, the project is very significant as it clearly defines who we are and what we stand for.

"We believe the research into the legacy of our great king Moshoeshoe will open doors for more research into the life of Basotho in general.

"Africa as a whole can learn from his leadership style," he said.
