Vishuis
Vishuis will be trying to win their overall seventh Varsity hostel title on Monday.

Managing his players is of the utmost importance if the University of the Free State’s (UFS) Abraham Fischer Residence (Vishuis) is to claim a fourth straight and seventh overall national hostel title, says Zane Botha, head coach of the hostel team at the UFS.

The Varsity Hostel competition, which will be taking place in Stellenbosch, has been drastically shortened to only three days of rugby because Steinhoff has withdrawn their sponsorship.

If Vishuis makes it to the final, they will play three matches in four days.
They will face the Kovacs of the University of the Western Cape (UWC) on Friday 12 March 2019, followed by the semi-final on Saturday and the final on Monday. The final will take place at 14:00 and will be broadcast live on SuperSport.

“This will be new territory for us. We will have to make good tactical decisions; it won’t be possible for a prop to play for 70 minutes in all three encounters,” said Botha, who is in his third year with the hostel.

The team played three warm-up matches, which they won convincingly. We still have the core of last year’s team, together with some exciting youngsters.
Botha explained that they kept to their strategy of working harder than anyone else on the practice field and during matches. In last year’s final, Vishuis defeated Patria of the North-West University by 55-29, which was the biggest winning margin in the 11 years of the competition. Vishuis walked away with the crown in 2010, 2012, 2013, 2016, 2017, and 2018.

Plant scientists address wheat rust diseases at SASPP congress

In his research, Dr Botma Visser, researcher in the Department of Plant Sciences at the University of the Free State, highlighted the population dynamics of the stem rust fungus (Puccinia graminis f. sp. tritici) in Southern Africa. In recent years, two foreign stem rust races were introduced to South Africa, and a local virulence adaptation occurred in a third.

All of these races form part of the Ug99 group, a highly virulent collection of rust races endangering wheat production in many parts of the world. Despite the fact that half of the members of the Ug99 race group is prevalent in South Africa, Dr Visser’s work has clearly shown that Ug99 did not have its origin here. This emphasised the need to include neighbouring countries in the annual stem rust surveys, to proactively identify new races that could threaten local wheat production. In his research, Dr Visser also mentioned the way in which he has optimised modern molecular tools to accurately detect Ug99 isolates.

Dr Visser is one of three scientists from the Department of Plant Sciences that addressed delegates attending the biennial congress of the Southern African Society for Plant Pathology (SASPP) on the Bloemfontein Campus earlier this month on progress regarding research on wheat rust diseases conducted at the UFS.

Howard Castelyn, a PhD student in Plant Sciences, presented his research on quantifying fungal growth of the stem rust pathogen in wheat varieties displaying genetic resistance. This resistance, which is best expressed in adult plants, has the potential to remain durable in the presence of new rust variants. His presentation at the congress focused on optimising microscopic and molecular techniques to track fungal development in stem tissues of adult plants. These results now allow scientists to link rust infection levels and cellular responses with particular resistance genes expressed by the wheat plant, and contributing to the understanding and exploitation of durable resistance.

Prof Zakkie Pretorius presented his research, explaining how new genetic diversity for resistance to the stripe (yellow) rust fungus (Puccinia striiformis) is discovered, analysed and applied in South Africa. This research, conducted in collaboration with Dr Renée Prins and her team at CenGen, is unravelling the genetic basis of stripe rust resistance in a promising wheat line identified by Dr Willem Boshoff, a plant breeder at Pannar. The line and DNA markers to track the resistance genes will soon be introduced to South African wheat breeding programmes.

The rust research programme at the UFS contributes significantly to the successful control of these important crop diseases.

In addition to the contributions by the UFS, rust fungi featured prominently at the SASPP, with first reports of new diseases on sugar cane and Acacia and Eucalyptus trees in South Africa. A case study of the use of a rust fungus as a biological control agent for invasive plant species in the Western Cape, was also presented.
