Abstract:
We undertook a historical review of wheat varietal improvements in South Africa from 1891 to 2013,
thus extending the period of previous analyses. We identified popular wheat varieties, particularly those
that form the basis for varietal improvements, and attempted to understand how policy changes in the
wheat sector have affected wheat varietal improvements in the country over time. The empirical analysis
is based on the critical review of information from policies, the varieties bred and their breeders, the
years in which those varieties were bred, and pedigree information gathered from the journal Farming
in South Africa, sourced mainly from the National Library of South Africa and the International Maize
and Wheat Improvement Center (CIMMYT) database. A database of the sources and uses of wheat
varietal innovations in South Africa was developed using information from the above sources. The data,
analysed using trend and graphical analysis, indicate that, from the 1800s, wheat varietal improvements
in the country focused on adaptability to the production area, yield potential and stability and agronomic
characteristics (e.g. tolerance to diseases, pests and aluminium toxicity). An analysis of the sources of
wheat varietal improvements during the different periods indicates that wheat breeding was driven initially
by individual breeders and agricultural colleges. The current main sources of wheat varietal improvements
in South Africa are Sensako, the Agricultural Research Council’s Small Grain Institute (ARC–SGI) and
Pannar. The structural changes in the agricultural sector, particularly the establishment of the ARC–SGI
and the deregulation of the wheat sector, have helped to harness the previously fragmented efforts in
terms of wheat breeding. The most popular varieties identified for further analysis of cost attribution and
the benefits of wheat varietal improvements were Gariep, Elands and Duzi.
SIGNIFICANCE :
• These findings form the basis for the next analysis focusing on the attribution of the benefits and costs in
terms of investment in wheat breeding in South Africa.
