True Breeding Strains

True-breeding strains will reproduce true to type from their own seeds, so different generations will share similar characteristics. True-breeding strains are either:

Pure-breds: traditional land races that have only interbred with similar strains and so have almost identical genes.

Or

Stabilized Hybrids: Hybrids that have been created by breeders but then continually inbred until their characteristics are Stabilized from generation to generation. Very few strains are Stabilized hybrids as this takes considerable time for breeders to achieve. All true-breeding strains are therefore ideal for using as parent plants when creating new F1 hybrids.
