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.

Full week of graduation ceremonies at UFS in April

2015-04-10

Autumn always sees the UFS’s first graduation ceremony of the year on the Bloemfontein Campus.

From 14 – 17 April 2015, graduates will once again be rewarded for their hard work while top speakers will address them in the Callie Human Centre. There will be a ceremony at 09:00 and at 14:30 each day on all four days of the graduation.

The programme for the 2015 April Graduation is as follows:

Tuesday 14 April 2015:

Professor Himla Soodyall will be the speaker at both ceremonies on this day. Prof Soodyall is a Medical Scientist for the South African Institute for Medical Research. She is also a Principal Medical Scientist for the National Health Laboratory Service, and a Director for the Human Genome Diversity and Disease Research Unit at the University of Witwatersrand.

During the first ceremony of the day at 09:00, all diplomas/certificates and B degrees in the Faculty of Natural and Agricultural Sciences will be awarded. Only Honours degrees in the Faculty of Natural and Agricultural Sciences will be awarded at the 14:30 ceremony.

Wednesday 15 April 2015:

Wednesday will see Ndumiso Hadebe take the stage to address graduates at both ceremonies.

At the age of 23, Hadebe is the Founder and Managing Director of Master Frontiers Consulting, a firm that capacitates leaders and managers to achieve business goals through their people. He worked previously as a Researcher at Shanduka Black Umbrellas, a flagship enterprise and supplier development programme of the Shanduka Foundation.

He has been received numerous awards for excellence in leadership, such as the Sedibeng District Municipal Mayor’s Award for Service and Leadership. He is a Brand South Africa Ambassador and Read Educational Trust Ambassador.

All diplomas/certificates, B and Honours degrees in the Faculty of Economic and Management Sciences, except B Com degrees, will be awarded during the morning ceremony at 09:00. Later, at the 14:30 ceremony, only B Com degrees in the Faculty of Economic and Management Sciences will be awarded.

Thursday 16 April 2015:

Multiple award winning South African TV presenter, Leanne Manas, will be the speaker at both Thursday ceremonies.

Manas has graced our screens for over a decade. Not many broadcasters can boast having had live TV experience, 5 days a week for 12 years. She is currently the anchor of SABC 2’s flagship breakfast programme, Morning Live. Leanne is a qualified Speech and Drama teacher. having studied at London Trinity College. She also has an Honours degree in English.
Diplomas/certificates up to and including Honours degrees in the Faculty of the Humanities, Social Sciences, and Communication Sciences will be awarded during the ceremony at 09:00. The 14:30 ceremony will have diplomas/certificates up to and including Honours degrees in the Faculty of the Humanities’ other qualifications except for Social Sciences and Communication Sciences.

Friday 17 April 2015:

Dr Maria Phalime will be the speaker at both ceremonies on Friday.

Phalime is a medical doctor and award-winning author. She practiced for a brief period as a general practitioner in South Africa and the United Kingdom, before leaving medical practice to pursue non-clinical interests. She has worked in trade and investment promotion, and has undertaken research and consulting in the areas of economic development and business facilitation.

Diplomas/certificates up to and including Honours degrees in the Faculty of Education (CE, NPDE and ACE excluded) will be awarded during the ceremony at 09:00. Diplomas/certificates up to and including Honours degrees in the Faculties of Health Sciences, Law, and Theology will be awarded at the 14:30 ceremony.
