True breeding = IBL

What is an F1, F2, and IBL?

An IBL (inbred line) is a genetically homogeneous strain that grows uniformly from seed. A hybrid is a strain made up of two genetically unlike parents, IBL or hybrid. When you cross two different IBL strains for the FIRST time, it is called the F1 generation. When you cross two of the same F1 hybrid (inbreed), it is called the F2 generation. The process of selective inbreeding must continue at least until the F4 to stabilize the recurrently selected traits. When you cross two specimens of an…

How do I create a true breeding strain?

Contributed by Vic High: I’ve been hearing a fair bit of confusion from many on how to create a true breeding strain and so I’m writing this page to try and help shed some light on the subject. There are a few situations where a plant breeder would want to create a true breeding strain (IBL) and a few ways of accomplishing the task. But understanding the subtle differences of the various techniques is not so easy. This paper will attempt to give a basic understanding of what is actually happeni…
