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. WebThe mating or crossing of two plants or lines of dissimilar genotype is known as hybridization. In plants, crossing is done by placing pollen grains from one genotype i.e., male parent, on the stigma of flowers of other genotype i.e., female parent. ...

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.
