Modern plant breeding, whether classical or through genetic engineering, comes with issues of concern, particularly with regard to food crops. The question of whether breeding can have a negative effect on nutritional value is central in this respect. Although relatively little direct research in this area has been done, there are scientific ...
Cross-pollination, where pollen from one plant can only fertilize a different plant; Asexual propagation (e.g. runners from strawberry plants) where the new plant is genetically identical to its parent; Apomixis (self-cloning), where seeds are produced asexually and the new plant is genetically identical to its parent
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 ...
Hybridization sometimes results in introgression, which can occur in response to habitat disturbance that puts plant species into contact with each other. [2] Introgression is gene transfer among taxa and is a result of hybridization, followed by repeated backcrossing with parental individuals.

Gene pyramiding is the simultaneous selection for and/or introduction of multiple genes during plant breeding. [1] Objectives of gene pyramiding includes 1) enhancing trait performance by combining two or more complementary genes, 2) remedying deficits by introgressing genes from other sources, 3) increasing the durability.

Germplasm resources allow for more genetic assets to be used and integrated for agricultural systems for plant breeding and bringing about new varieties. In addition, researchers are looking at crop wild relatives (CWRs) that could expand gene pools of crop species and provide more ability to select target traits.
Embryo rescue is one of the earliest and successful forms of in-vitro culture techniques that is used to assist in the development of plant embryos that might not survive to become viable plants. [1] Embryo rescue plays an important role in modern plant breeding , allowing the development of many interspecific and intergeneric food and ...
