Abstracts of Current Research
Tomato breeding: About 20-30% of the harvested tomato crop is usually
lost because of softness or rotting. This problem has recently been
solved by incorporating one or more of several special genetic factors
into commercial varieties. About 300 varieties of this type have been
released and 50 are now grown successfully. Further improvement of
shelf-life and of taste is our goal. At present, about 40% of outdoor
tomatoes and 90% of greenhouse tomatoes in Israel are varieties
developed at the Faculty of Agriculture. Seed of Faculty tomato
varieties is produced by Israeli seed companies and exported to many
