Abstract

The purpose of mutation induction is to accelerate the rate of mutation during the emergence of new plant species. Since spontaneous mutations are uncommon, it is challenging to employ them in plant breeding. Previously, physical (such as gamma radiation) and chemical (such as ethyl methane sulphate) mutagen treatments were employed to produce mutations in seeds and vegetatively propagated crops. Plant mutagenesis maturation has been accelerated by recent developments in high-resolution molecular and biochemical techniques. Characteristics that are virtually impossible to identify through conventional breeding are developed and molecularly defined using a large number of mutant populations and innovative screening tools. The numerous methods and techniques that molecular breeding researchers have access to at the moment are fully summarized on this page, along with how these resources complement those used in traditional breeding. TILLING (Targeting Induced Local Lesions in Genomes) and phenotypic screening are used in the evaluations. The genetic-phenotype gap can be closed using a variety of methods, which are discussed in the conclusion.
