Abstract:Plant breeders examine species differences to find genotypes with desirable characteristics. Chronological spontaneous mutation, genotypic recombination within a species, and interactions with the environment contribute to natural variance. Mutations are responsible for all variations in biological populations, including plants. A sufficient amount of genetic variation is essential for any crop improvement program. If the trait of interest does not appear in the normal population, mutagenesis must be used to produce new alleles that regulate the trait. As a consequence, both biological developmental evolution and plant breeding require mutations. Induced mutation-based breeding has been used to produce new alleles or genes in existing genotypes, as well as to alter physiological, agronomical, and quality traits in crop plants. Mutagenesis is the process of inducing mutations in seeds and other parts of plants through chemical, physical, and biological agents. These agents are known as mutagens. Fresh germplasm lines containing new traits/ alleles may be used as direct releases of new varieties or as parental lines in breeding programs. Induced mutagenesis has resulted in the creation of a vast number of improved varieties and genetic stock worldwide in many pulse crops including lentil. A brief review of development of multipodding mutant and other important literature of various aspects particularly related to mutation breeding of lentil (Lens culinaris Medik.) and other economically important related crops has been presented in this work.
