Inbreeding of plants

WebPlant breeders can use self-pollination as a type of inbreeding, creating plants that are genetically more identical and that produce identical offspring after many generations. Crossbreeding This is often used to produce offspring with desirable characteristics from two different individuals.

Autogamy - Wikipedia

WebPlants can be predominately outbreeding, inbreeding, or some mixture of the two. In many flowering plants specific mechanisms have evolved that promote one of these systems. Outbreeding, also called outcrossing, allogamy, or xenogamy, is the transfer of gametes from one individual to another, genetically different individual. The general ... Evolutionary plant breeding describes practices which use mass populations with diverse genotypes grown under competitive natural selection. Survival in common crop cultivation environments is the predominant method of selection, rather than direct selection by growers and breeders. Individual plants that are favored under prevailing growing conditions, such as environment and inputs, contribute more seed to the next generation than less-adapted individua…
