Inbred plant
WebInbreeding is producing seed by selfing over 5–7 generations to develop plants that are highly homozygous at most loci in their genomes. Homozygosity results in identical … WebJul 6, 2024 · Medicago sativa L., also known as alfalfa or lucerne, is a perennial outcrossing plant. Most alfalfa cultivars are autotetraploid (2 n = 4X = 32), and the species exhibits strong inbreeding depression ( Li and Brummer, 2009 ). Bees are required for pollination and seed production ( Bohart, 1957 ).

WebInbreds usually are produced by continuous generations of self-pollination. If an individual plant is heterozygous at a locus, approximately seven generations of self-pollination are …
WebAn extreme example of inbreeding is a selfing, a breeding system observed in some plants. Less extreme inbreeding is not uncommon in animal and human populations. Here, the main reasons for inbreeding are usually geographical (e.g., mice live in very small interbred colonies – dems – which are usually established by a few mice and are quite ... 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).
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. See more Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically.

WebHybrid seeds are used to improve the characteristics of the resulting plants, such as better yield, greater uniformity, improved color, disease resistance. An important factor is the heterosis or combining ability of the parent plants. Crossing any particular pair of inbred strains may or may not result in superior offspring.
