What is inbred in plants? WebAn inbred is a pure-breeding strain of corn.

"WebInbred lines are homozygous, and, therefore, pure-breeding plants which can be maintained by selfing, unless you are using a male sterile or self-incompatibility system. This facilitates perpetual reproduction of the hybrid and consistency of phenotype and performance, as well as a method of proprietary control of the germplasm. " - Inbred plant
