Short CV

Willem HP Boshoff was born on 10 January 1971 in Mossel Bay.  He matriculated in 1989 from Point High School in Mossel Bay.  After completion of his BSc Agric. and BSc Agric. Honours degrees in Plant Pathology at UFS in 1995, Willem was appointed by the ARC-Small Grain Institute, Bethlehem, to work on stem rust surveillance and pre-breeding for rust resistance in wheat.  He obtained his M.Sc. Agric. degree in 1997 and his PhD in 2001, all at UFS.  His master’s study dealt with Fusarium head blight and for his PhD the main focus was on stripe rust occurrence, epidemiology and control strategies.  This pioneering study was inevitable after the pathogen had been observed for the first time in 1996, causing extensive and severe epidemics, on wheat in South Africa.  After completion of his studies SGI appointed Willem as their spring wheat breeder for the irrigated production regions.  In 2003 he joined Pannar Seed (Pty) Ltd. as their winter wheat breeder where he acted as breeding lead from 2006 to 2016, releasing several successful varieties. Willem was appointed as Senior Lecturer by the UFS in January 2017 in the field of rust pathology.  Willem will continue and expand research on rust diseases of field crops, teach undergraduate modules in Plant Pathology, and advise post-graduate students on research projects.

 

Research

Focus on rust diseases of field crops including pathogen variability and genetic resistance.  

 

Area(s) of interest

My main research interest includes pathogenic variation of rust pathogens of field crops, genetic resistance including cultivar characterisation and the identification and genetic analyses of new sources of genetic resistance with the potential of durable control. 

 

Area(s) of expertise

I have been extensively involved in determining of pathogenic variation in rust pathogens of small grains.  This include the successful characterisation of the establishment, epidemiology and determining of pathogenic variation in the wheat stripe rust fungus in South Africa.  I was responsible for determining the efficiency of chemical control against wheat leaf- and stripe rust, which included the use of foliar sprays, optimising timing of applications and the use of chemical seed treatment to combat seedling infection.  My expertise on field resistance to rust pathogens include the successful identification of various wheat germplasm accessions with effective resistance to local stem-, leaf- and stripe rust pathotypes. I was directly involved in the establishment of breeding, evaluation and selection protocols to successfully introduce and combine new sources of resistance in various locally adapted germplasm backgrounds and successfully released higher yielding wheat cultivars with improved field resistance. 

 

Impact: Contributed directly and significantly towards increased wheat yield stability and production in South Africa through the release of new high yielding cultivars with increased field resistance to pests of economic importance. Through extensive publication in the popular media and farmer’s days played a significant role in transferring data and the latest available technologies to where it is applied at farm level.
