Inbred plant
WebPlant lines are considered inbred when the offspring (progeny) from a self-fertilized plant look identical to the parent, as well as identical to one another. …. It is important to note that plant species vary in their generation time (time from seed to offspring seed). 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.

WebMay 14, 2024 · Inbreeding often results in offspring that are weaker than their parents which can reduce the plant’s chance of survival. Many plants rely on animals to help them to breed. For example, bees carry pollen – containing the male sex cell – to other flowers which then fertilize the plant to produce seeds. WebThe inbreeding coefficient can have any value between 0 and 1.0 although it is unlikely for it to have a value much above .5 in most herds of livestock. It is fairly easy to have it approach 1.0 in plant species where selffertilization is possible. There are also some lines of laboratory animals with very high average inbreeding coefficients.
WebTechnically, inbreeding is defined as the mating of animals more closely related than the average relationship within the breed or population concerned. Matings between animals less closely related than this, then, would constitute outbreeding. These two systems of mating, with varying intensities in each, are described in Table 1.
