CACTUS PEAR RESEARCH IN SOUTH AFRICA: PAST, PRESENT AND FUTURE - J. Potgieter

The spiny cactus pear was introduced into South Africa more than 350 years ago.  Earlier research work focused into ways of chemical and biological control of this invader plant.  In later years, the emphasis shifted towards the use of the spineless cactus pear as a drought-tolerant fodder crop for arid and semi-arid parts of South Africa and the potential utilization of the spiny types.  Only in the 1970’s was the fruit production potential of the plant placed under the research spotlight.  As a minor fruit and fodder crop, it was always supported on an ad hoc basis by a variety of institutions, ranging from provincial state departments, research institutions and universities throughout the country.  This paper will give an overview of important research activities from the 1960’s to date.  Important contributions of organizations and individuals will be highlighted, while future research needs will be indicated.
