'''Plant breeding''' is the science of altering the traits of [[plants]] in order to produce desired characteristics. It has been used to improve the quality of [[nutrition]] in products for humans and animals. Plant breeding can be accomplished through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to more complex molecular techniques (see [[molecular breeding]]).

==History==
The history of plant breeding dates back to the domestication of the first agricultural plants, thousands of years ago, leading to the development of more productive, hardier and more disease-resistant varieties. Early plant breeders selected for traits such as yield, taste, and hardiness. The science of plant breeding took a big leap forward in the 20th century with the discovery of [[genetics]], the establishment of [[Mendelian inheritance]] principles, and the development of techniques such as [[hybridization]], [[mutation breeding]], and [[genetic engineering]].

==Techniques==
===Conventional Breeding===
Conventional breeding involves the crossing of plants with desirable traits, and the subsequent selection of offspring with the preferred combination of traits. This method relies heavily on [[phenotype|phenotypic]] selection and is time-consuming but has been the backbone of plant breeding for centuries.

===Molecular Breeding===
Molecular breeding, or marker-assisted selection, uses [[molecular biology]] tools to select plants that possess a desirable trait, even if the trait is not visibly apparent. This technique can significantly speed up the breeding process by selecting plants at the DNA level.

===Genetic Engineering===
[[Genetic engineering]] involves the direct manipulation of an organism's genes using biotechnology. It is a more precise method of plant breeding that can introduce new traits into a plant species from a different species.

==Objectives==
The objectives of plant breeding vary but generally include:
* Increasing crop yield
* Developing plants resistant to pests and diseases
* Improving nutritional value
* Enhancing taste, texture, and appearance
* Increasing tolerance to environmental pressures, such as salinity, extreme temperatures, and drought

==Challenges==
Plant breeding faces several challenges, including the long time frames required to develop new plant varieties, the complexity of plant genomes, and the ethical and safety concerns associated with [[genetic modification]]. Additionally, climate change presents new challenges for plant breeders, as plants must now be bred to withstand changing environmental conditions.

==Future Directions==
The future of plant breeding lies in the development of new technologies such as [[CRISPR]] and other gene-editing tools, which promise to increase the precision and efficiency of plant breeding. Additionally, there is a growing interest in the development of crops that can contribute to sustainable agriculture practices.
