The idea of plant improvement is conceived by Dr SJ du Plessis.
The first step is taken – conducting a programme based on the visual selection of suitable plant material.
The South African Plant Improvement Association (Plantas) is established.
A fruit improvement scheme is designed specifically for South Africa.
The Deciduous, Canning and Dried Fruit Boards establish the South African Plant Improvement Organisation (SAPO) as a partnership agreement with equal representation and clear objectives of supplying improved plant material to the industry.
Excelsior Farm is developed by SAPO as a centralised propagation and multiplication unit.
The first super plant rootstock material, true to type and free of known viruses, is issued to nurserymen.
Nurseries supplied the first super plant trees to producers.
