Prior to 1960 before the green revolution in Asia farmers where growing open pollinated varieties which would bring very low yield. However in 1960 Seed Co produced SR52 which is the first single cross maize hybrid to be commercialised in the world and forms the basis of maize breeding in Zimbabwe and Eastern and Southern Africa region.
The experiment was conducted by Allan Rattary and Harry Arnold at the Harare Research Station and they became the pioneers of moving from open pollinated to single cross pollinated variety. Seed Co commercialised this variety first in the world before farmers and researchers in the world.
We have since evolved to creating new varieties that are doing very well in the market.
