Inbred plant
WebA homozygous and homogeneous line that is produced by inbreeding and selection is known as inbred line. Inbred lines are produced by continued inbreeding. Inbreeding refers to mating between closely related individuals. In plant breeding, selfing and sib mating are the common forms of inbreeding. Sib mating refers to crossing between individuals … 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.

WebInbreeding is also used to reveal deleterious recessive alleles, which can then be eliminated through assortative breeding or through culling. 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.
