The Fruit Morphology link will direct you to fruit images from a large collection of Solanum lycopersicum varieties and to flower and fruit development in S. pimpinellifolium.

The Fruit Morphology Loci link will direct you to detailed information about major loci controlling tomato fruit shape.

The QTL Studies link will direct you to molecular marker files and images of fruit from F2 or BC1 plants used to map the fruit morphology loci.

The Molecular Map link will direct you to PCR-based markers that are polymorphic between S. lycopersicum and S. pimpinellifolium accession LA1589. These markers cover part of the tomato genome and are anchored to tomato RFLP markers.

The Search link will allow you to search for specific varieties, country of origin, a shape or size category, and the fruit shape gene.
