Prof Maryke Labuschagne is a Professor of Plant Breeding in the UFS Department of Plant Sciences.

A new research chair at the University of the Free State (UFS), led by Prof Maryke Labuschagne, a Professor of Plant Breeding in the UFS Department of Plant Sciences, hopes to increase food and nutritional security in South Africa through crops that have intrinsic high nutritional value.

The Breeding Climate-Resilient Vegetables and Grains research chair was established in partnership with the Agricultural Research Council (ARC) and the Department of Agriculture, Land Reform and Rural Development (DALRRD). It will be hosted within the Faculty of Natural and Agricultural Sciences (NAS) alongside the other ARC-DALLRD-UFS research chairs, namely Climate Change and Agriculture, Innovative Agro-processing for Climate-smart Food System, Agriculture Risk Financing and Sustainable Livestock Production. 

The aim of the new ARC-DALLRD-UFS research chair, explains Prof Labuschagne, who is also leading the National Research Foundation (NRF) SARChI Chair in Diseases and Quality of Field Crops, is to breed climate resilient crops with high levels of nutrients such as iron, zinc, provitamin A and essential amino acids, as well as disease resistance, in collaboration with the ARC.

Breeding of climate resilient crops

“We are all aware of the need for food security in South Africa. Climate change is already negatively impacting food production. With this research chair, in collaboration with the ARC, we hope to increase food security through crops that have intrinsic high nutritional value, for example, high levels of iron and zinc and provitamin A, of which there are high levels of deficiency in our population, and at the same time increase climate resilience (such as heat and drought tolerance) in these crops.

“We will be working on breeding climate-resilient, nutrient-rich and disease-resistant pigeon pea and cowpea cultivars; maize rich in provitamin A, iron and zinc; highly nutritious sweet and bitter sorghum; rust-resistant and good-quality wheat; high-yielding and nutritious indigenous vegetables such as amaranth and amadumbi; and research on potato, sweet potato and cassava for human and industrial uses,” says Prof Labuschagne.

The new chair will complement the research that is already being done for the SARChI chair, but with the ARC as partner. It will combine the expertise and resources of Plant Breeding at the UFS with that of the ARC-VIMP (Vegetable, Industrial and Medicinal Plants), ARC-GC (Grain Crops) and ARC-SC (Small Grains). The chair research will include orphan crops such as cowpea, pigeon pea and indigenous vegetables, as well as root and tuber crops such as potato and cassava, and cereals such as wheat, maize and sorghum.

Collaborative research

“The focus of this chair is on collaborative research and student training with the ARC, but the research area will still focus on the development of nutrient-rich and disease-resistant food-security crops. It will also have an additional focus of climate resilience, and the inclusion of orphan crops indigenous to Africa and South Africa.”

Prof Labuschagne says it is exciting that collaborative research can now be done with the unique expertise and resources (laboratory equipment, fields, greenhouses etc.) of several research institutes for the benefit of food and nutritional security in South Africa. Doing this research in a large team with lots of expertise in different areas will certainly yield more and better results with a larger impact on food security.

“This is a very exciting development in agricultural research now that we are part of a large team all working towards the same goal of improving food security, sharing expertise and resources and also doing collaborative training of MSc and PhD students who will become the scientists of tomorrow, taking this quest into the future.”

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, says this chair is aligned to the UFS Vision 130 strategy, shaped by excellence and impact, sustainability and society. “This distinguished chair led by Prof Labuschagne recognises exceptional achievement and pre-eminence in the field to catalyse and ignite new talent and new knowledge. It marks an exciting opportunity to deepen our understanding of breeding climate-resilient vegetables and grains aligned to our expertise in agriculture.”

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
