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.

Community builders honoured at Community Engagement Awards

The office of Community Engagement held its annual Community Engagement Awards at the University of the Free State (UFS) on 5 October 2016. This year, the ceremony celebrated people who gave themselves selflessly to improve the lives of those around them who are less privileged. Key players in various sectors of society were recognised and honoured for their contribution and commitment towards a common good.

Dr Richard Teare, president of the Global University for Lifelong Learning (GULL), was the keynote speaker at the ceremony. GULL, a non-profit foundation, operates across the world, providing access to lifelong learning for communities, giving each individual an opportunity to make a difference in their world. Dr Teare talked of places that lack the provision and infrastructure to access higher education and said that through community service programmes, social and economic development was enhanced, and the necessary expertise and resources were provided to drive a community towards a greater good. “Community engagement espouses academic excellence—it enables people to discover their full potential.”

Through its partnership with GULL, the University of Free State has worked with women from Bloem Shelter, an organisation that provides assistance to underprivileged women and children from diverse walks of life. The women were equipped with the necessary skills and knowledge they needed to become self-sufficient - an experience that has yielded positive, constructive change in the women’s lives. 

The awards also acknowledged the boldness and innovative support of members of the Free State community in their various sectors. Among those awarded was Dr Choice Makhetha for her contribution in building capacity for those involved in community service programmes. She also designed and created approaches to improve situations in schools, churches, community organisations and small businesses. Also presented with an award was Dr Dipane Hlalele of the Qwaqwa Campus for his role as principal investigator in two National Research Foundation (NRF) -funded projects; Rural Relational Leadership and Sustainable Rural and Urban Connection. The ICT Innovation in School Education division of the South Campus was also recognised for its Internet Broadcast Project (IBP), which provides lessons on different subjects to 72 000 learners and 3 000 teachers each week.
