UC Davis has an extensive collection of tomato genotypes. The collection includes both varieties of Lycopersicon esculentum (the tomato we are all familiar with) and other species in the same genus (Lycopersicon). The wild relatives of L. esculentum may have desirable genes which can be crossed into L. esculentum by plant breeders. The UCD collections were made and are maintained by Dr. Charles Rick.

3. Fuzzy Tomatoes?

Lycopersicon pennellii
This species has sticky hairs on the leaves and petals. You can see one function of these--to catch pesky insects. The fruits are also fuzzy.
