Webcycles are repeated until inbred lines that no longer show significant phenotypic variation between individuals are generated. These lines are often called “true breeding” inbred lines. Plant lines are considered inbred when the offspring (progeny) from a self-fertilized plant look identical to the parent, as well as identical to one another.
