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.
This method is used to improve the overall population by positive or negative mass selection. Mass selection is only applied to a limited degree in self-fertilizing plants and is an effective method for the improvement of landraces. This method of selection will only be effective for highly heritable traits.
The adoption of traditional plant breeding methods to enhance nutritional benefits of locally grown food crops such as Bambara groundnut is an economic and affordable strategy to decrease malnutrition in Africa. [27] The form and colour of Bambara groundnut were all important factors to optimize the best extraction yield of phytochemicals ...
Micropropagation or tissue culture is the practice of rapidly multiplying plant stock material to produce many progeny plants, using modern plant tissue culture methods. [1] Micropropagation is used to multiply a wide variety of plants, such as those that have been genetically modified or bred through conventional plant breeding methods.
Traditional breeding methods are slow and take 10–15 years for cultivar development. Another disadvantage is inefficiency of selection in early generations because of heterozygosity. These two disadvantages can be over come by DHs, and more elite crosses can be evaluated and selected within less time.
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.
Farmers have used traditional breeding methods for millennia, wild maize (Zea mexicana) is routinely grown alongside maize to promote natural crossing and improve yields. More recently, plant breeders have utilised CWR genes to improve a wide range of crops like rice ( Oryza sativa ), tomato ( Solanum lycopersicum ) and grain legumes .
Cisgenesis is a product designation for a category of genetically engineered plants. A variety of classification schemes have been proposed [ 1 ] that order genetically modified organisms based on the nature of introduced genotypical changes, rather than the process of genetic engineering.
