Background Information This inbreeding goes on for several generations, the plants becoming progressively weaker but purer in strain. Two of these types are then cross-bred to produce a healthy hybrid corn type.

Sponsored by FAO, an experimental programme with hybrid maize began in Europe in 1948, and was then continued and expanded. At this experiment station in Bergamo, much work was done on inbreeding regular types of corn to obtain pure strains, then crossbreeding to obtain hybrid varieties.

In order to do this, both the tassel and the ear of the corn plant must be protected from outside pollination.
