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.

It is better for Super Rugby teams not to have the ball, which also leads to reduced overall playing time in matches.

This observation is from a study by the University of the Free State on the difference between winning and losing teams. Statistics between 2011 and 2015 show that Super Rugby winning teams kick more and their defence is better.

These statistics were applied by Riaan Schoeman, lecturer in Exercise and Sport Sciences, Prof Derik Coetzee, Head of Department: Exercise and Sport Sciences, and Prof Robert Schall, Department of Mathematics and Actuarial Sciences. The purpose of the study, Changes in match variables for winning and losing teams in Super Rugby from 2011 to 2015, was to observe changes. Data on 30 games (four from each team) per season, supplied by the Cheetahs via Verusco TryMaker Pro, were used.

About two minutes less action
“We found that the playing time has decreased. This is the time the ball is in play during 80 minutes,” says Schoeman. In 2011, the average playing time was 34.12 minutes and in 2015 it was 31.95.

“The winning team has less possession of the ball and doesn’t want it. They play more conservatively. They dominate with kicks and then they play,” says Prof Coetzee, who was the conditioning coach for the Springboks in 2007 when they won the World Cup.

Lineouts also more about kicking
As a result, the number of line-outs also increased (from 0.31 per minute in 2011 to 0.34 in 2015) and the winning teams are better in this regard.

“The winning team has less possession of the ball
and doesn’t want it. They play a more conservative
game. They dominate with kicks and then they play.”

Schoeman believes that rule changes could also have contributed to reduced playing time, since something like scrum work nowadays causes more problems. “When a scrum falls, the time thereafter is not playing time.”

According to Prof Coetzee, rucks and mauls have also increased, (rucks from 2.08 per minute in 2011 to 2.16 in 2015 and mauls from 0.07 per minute in 2011 to 0.10 in 2015). “The teams that win, dominate these areas,” he says.
