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. WebAn issue related to selection differential is the total number of plants selected (i.e., the number of parents) each cycle. Addressing this issue involves the concept of inbreeding. Inbreeding occurs whenever related individuals mate. The most extreme form of inbreeding is self-pollination because the same plant is both the female and male parent.
