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.

B. Iur. programme in Occupational Risk Law first of its kind in the country

2010-11-26

The University of the Free State (UFS) will offer a B.Iur. degree programme in Occupational Risk Law from 2011.

This programme of the Faculty of Law is the first of its kind to be offered in South Africa and positions the UFS in the forefront of this field of study.

The programme is designed to develop and qualify professionals, knowledgeable in the field of occupational risk law as prescribed by South African legislation and international best practices. It further offers a qualification based on a well-researched basis of applicable legal principles, combined with safety, health, environmental and quality risk management principles applicable to employers and employees in a specialised industry.

The B.Iur. (Occupational Risk Law) has been developed by experts within the parameters of international comparability, according to research-based identification of career demands and requirements in the fields mentioned.

By introducing this programmesignificant progress will be made towards achieving the nationally stated objective of legal safety, health and environmental quality assurance in the workplace and within the broader community. The programme will also encompass the values and standards prescribed by the Institute of Safety Managers. This will provide them with a further step towards the regulation of the professional en ethical standards in the field of legal safety, health and environmental quality assurance.

With the programme, the UFS not only creates a unique opportunity for stakeholders and learners to add meaningful value to their careers, but also exerts a meaningful influence on the industry and society in terms of the acquisition of a most appropriate type of qualification. The B.Iur. (Occupational Risk Law)degree therefore offers a meaningful contribution towards the industry through addressing the increasing demand for career opportunities in the field of legal safety, health and environmental quality compliance.

The new programme is the result of an agreement between the faculty and its partner, IRCA Global. The university officially launched its partnership with IRCA Global, an international supplier of risk management solutions pertaining to safety, health, the environment and quality in 2008. As part of the agreement, the UFS will offer short learning programme, a diploma and a degree in Risk Management.

IRCA Global is a South African company in the international risk control and SHEQ environments with filials in Africa, Australia, India, Eastern Europe, and South America.

In the interim IRCA Global has continued with the marketing of the programme, with the result that hundreds of potential students are waiting for the launching of the programme. The faculty is geared towards offering the programme in e-learning. New modules will also be offered with the help of IRCA’s trained and skilled facilitators. The faculty also utilises the partnerships entered into with IRCA to appoint practising specialists as part-time lecturers for the occupational risk law component of the programme as well as to develop a new specialist component amongst the permanent staff.

The programme is already active and students can register for the first semester 2011 (study code 3324, programme code M3000). Direct your enquiries to Cora-Mari de Vos at 051 401 3532 or devosc@ufs.ac.za.

The programme consists of fundamental modules of the LL.B. and B.Iur., as well as short learning programmes in the Faculty of Law and specially developed core modules in occupational risk law. The B.Iur.in Occupational Risk Law enables successful candidates to enrol for applicable Post Graduate Diplomas or a cognate Honours Degree. Obtaining one of these qualifications provides the platform to articulate to Magister degrees. Horizontal articulation possibilities exist with the accredited Baccalaureus of Law (LL.B.) which is presented by several institutions in the country.
