Mutation breeding is commonly used to produce traits in crops such as larger seeds, new colors, or sweeter fruits, that either cannot be found in nature or have been lost during evolution. [ 9 ] Radiation

A significant environmental concern about using genetically modified crops is possible cross-breeding with related crops, giving them advantages over naturally occurring varieties. One example is a glyphosate-resistant rice crop that crossbreeds with a weedy relative, giving the weed a competitive advantage.
The selection in these crops is restricted to the material introduced from other sources, such as field plantations. The improvement of asexually propagated plants through induced mutations has distinct advantages and limitations. Any vegetative propagule can be treated with mutagens and even a single desirable mutant or a part of a mutated ...
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.
Atomic gardening is a form of mutation breeding where plants are exposed to radiation. Some of the mutations produced thereby have turned out to be useful. Typically this is gamma radiation – in which case it is a gamma garden [1] – produced by cobalt-60. [2]
TILLING (Targeting Induced Local Lesions in Genomes) is a method in molecular biology that allows directed identification of mutations in a specific gene.TILLING was introduced in 2000, using the model plant Arabidopsis thaliana, and expanded on into other uses and methodologies by a small group of scientists including Luca Comai.
Non-shattering phenotype is one of the prerequisites for plant breeding especially when introgressing valuable traits from wild varieties of domesticated crops. [1] A particularly important mutation that was selected very early in the history of agriculture removed the "brittle rachis" problem from wheat. [2]
