Plant breeders use different methods depending on the mode of reproduction of crops, which include: Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant; Cross-pollination, where pollen from one plant can only fertilize a different plant
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.
Xenia effects in maize. Xenia (also known as the xenia effect) in plants is the effect of pollen on seeds and fruit of the fertilized plant. [1] The effect is separate from the contribution of the pollen towards the next generation.
Mutation Breeding of Philippine Avocado; Although engaged in genetic engineering, the institute also uses mutation breeding, which is an alternative method of improving crop varieties. Small portions of avocado plant tissue (embryos) were allowed to grow (embryogenic cultures) and to differentiate into somatic embryos and shoots. Some of the ...
New Breeding Techniques (NBT), also named New Plant Engineering Techniques, are a suite of methods that could increase and accelerate the development of new traits in plant breeding. [1] These new techniques, often involve 'genome editing' whose intention is to modify DNA at specific locations within the plants' genes so that new traits and ...
Other molecular breeding tool include development of genetically modified crops that can tolerate plant stress. As a complement to the recent rapid progress in genomics , a better understanding of physiological mechanisms of dehydration response will also contribute to the progress of genetic enhancement of crop drought resistance.
This is a list of plant hybrids created intentionally or by chance and exploited commercially in agriculture or horticulture. The hybridization event mechanism is documented where known, along with the authorities who described it.
SibNIIRS has developed methods for breeding of new plant species using diploidization, introgressive hybridization, alloplasmia and aneuploidy. The breeders of the institute have developed varieties of spring wheat with a high level of gluten (28–30%) and protein (14–16%), as well as new varieties of oats.
