Inbreeding - an overview ScienceDirect Topics

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. In plant breeding, inbred lines are used as stocks for the creation of hybrid lines to make use of the effects of heterosis. Inbreeding in plants also occurs naturally in the form of self-pollination. Inbreeding can significantly influence gene expression which can prevent inbreeding depression.
