Hybrid Seed Production

Prof. Emeritus Esra Galun
In the 1950s, Prof. Emeritus Esra Galun’s research focused mainly on hybrid seed production in cucumbers and melons and on breeding disease-resistant cucumbers as well as cucumbers suitable for mechanical harvesting. Galun and his colleagues were the first to find a way to produce hybrid cucumber seeds without hand pollination.


This research resulted in the production of the first commercial hybrid cucumbers. Most cucumber varieties worldwide are still produced by modifications of the Institute technique, and cucumber seeds figure prominently in Israel’s agricultural exports.

The Institute’s disease-resistant Delilah cucumbers have captured a large portion of the market in Israel and much of the Middle East.
