Each plant receives a blend of pollen from a large number of individuals each having different genotypes. Such populations are characterized by a high degree of heterozygosity with tremendous free and potential genetic variation, which is maintained in a steady state by free gene flow among individuals within the populations.
Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. [1] It is used to improve the quality of plant products for use by humans and animals. [2] The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of applications.
Mating design is a schematic cross between the groups or strains of plants are made in a plant breeding that is common in agriculture and biological science. [1] The mating design in plant breeding has two main objectives: (1) to obtain information and understand the genetic control of a trait or behavior that is observed, and (2) to get the base population for the development of plant ...

Apomixis occurs in many plant species such as dandelions (Taraxacum species) and also in some non-plant organisms. For apomixis and similar processes in non-plant organisms, see parthenogenesis . Natural vegetative reproduction is a process mostly found in perennial plants, and typically involves structural modifications of the stem or roots ...
Mass Action Model – Holsinger's “mass action” model assumes that the proportion of selfed and out-crossed seeds produced is a function of rates of pollen transfer among plants and plant density. This model predicts that mixed mating can be a stable strategy when plants receive mixtures of self and out-cross pollen. [13]
Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo. This is a pertinent stage in the plant life cycle that is followed by dormancy and germination . [ 1 ]
Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
