Eu-Sol Tomato Seeds are bred from naturally occurring mutants, supplied by the CM Rick Tomato Genomics Resource Centre in Davis, California.

The seeds are produced by crossing two naturally occurring mutants. For more info information on how plants are crossed please click here

The first mutant has a recessive trait where its cotyledons are golden rather than green. Let's say this mutation is controlled by the recessive gene g. Its purple hypocotyl is pure breeding dominant (HH).

The second mutant has a recessive trait where its hypocotyl has no purple in it whatsoever and is light green. Let's say this mutation is controlled by the recessive gene h. Its green cotyledons are pure breeding dominant (GG)

As you can see we end up with a population entirely made up of plants with green cotyledons and purple hypocotyls. However, all of the seeds carry the recessive genes for golden cotyledons and light green hypocotyls. They all have the genes GgHh. These seeds are then self-fertilized which means they are bred with each other.

This produces the 9:3:3:1 ratio in the seeds in a pack of Eu-Sol Tomato Seeds.

The EU-SOL project is supported by the European Commission through the 6th framework programme.
