Dr Angeline van Biljon was elected as a member of the Southern African Plant Breeders’ Association (SAPBA) executive committee.

Ever wondered how seedless fruit such as lemons, watermelons, and grapes came to be?

Dr Angeline van Biljon, Senior Lecturer in the Department of Plant Sciences at the University of the Free State (UFS), was recently elected as a member of the Southern African Plant Breeders’ Association (SAPBA) executive committee where she will serve until March 2022.

She says it is a privilege to be a member of the team. “It is an opportunity to bring plant breeding to the community so that more people can know about the subject. For example, that seedless lemons, grapes, and watermelons does not just happen; that orange sweet potatoes with high beta-carotene are bred to combat vitamin A deficiency; and that wheat quality is important to make a good loaf of bread.”

This position also brings with it the possibility for her students to work closely with people in industry. “Other members of the committee are breeders in seed and breeding companies,” explains Dr Van Biljon.

Contributing on other platforms 

She was nominated and elected for this position during the SAPBA conference that was held at the Future Africa campus in Pretoria. Besides serving on the executive committee of SAPBA, she is involved with and are serving on several other platforms where she is making a difference in the plant breeding industry. 

Dr Van Biljon collaborates on wheat quality with researchers in the wheat industry at the Agricultural Research Council (ARC), Small Grain in Bethlehem. “I’m also a committee member of the Cereal Science and Technology – Southern African Association.”

For the past two years, she has been giving online lectures on biofortification as part of a National Research Foundation/Swedish Foundation for International Cooperation in Research and Higher Education (STINT/NRF) group in Alnarp in Sweden. However, she states a working visit to the Nanjing Agricultural University in Nanjing, China as one of her biggest highlights.


Today, I want to help students see the difference plant breeding can make in crop improvement and food security.


The difference plant breeding can make 

Although genetics was one of her passions as student, she later found herself as a flower breeder at the ARC Roodeplaat. Years later, she returned to the UFS to complete her PhD in Plant Breeding. And today, she wants to help students see the difference plant breeding can make in crop improvement and food security.

Currently, Dr Van Biljon is focusing on her research, which is the study of the nutritional value of various crops by determining, among others, the beta-carotene values of butternuts, the starch quality of wheat, and the tryptophan value of quality protein maize. “I also look at the influence of abiotic stress on the crop quality and nutritional value of various crops,” she adds.

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
