“…MutMap is a recent development for cloning EMS-induced alleles in rice using a bulked segregation strategy, and the method is further extended to enable alleles to be cloned without outcrossing (Abe et al, 2012;Fekih et al, 2013). Wilde et al (2012) presented an overview of screening in horticultural crops for natural or induced allelic diversity in over 100 candidate genes for traits of commercial interest, such as longer shelf-life (tomato, melon), improved starch quality (potato), and virus-resistance (peppers, tomato). An extension of the TILLING technique is 'TILLING by Sequencing' (TbyS) which relies on high throughput nextgeneration sequencing to speed up TILLING workflow (Tsai et al, 2011).…”

Agricultural sustainability and food security are major challenges facing continued population growth. Integration of existing and new technologies for the induction and exploitation of genetic diversity towards developing healthier, nutritious and productive crops is the need of the hour. Mutagenesis is a proven technology for the development of improved or novel varieties with desirable traits. Several mutant genes have been successfully explored, either directly or indirectly, to complement crop productivity. The advent of genomics approaches and plant genome sequencing has benefitted mutation discovery and mutant characterization. Plant mutant repositories are being established to serve as platforms for basic and applied research in crop improvement. This review briefly outlines the impact and molecular/genomic characterization of induced mutations in crop improvement.

“…More recently, horticultural crops that are developed through mutation breeding use molecular tools to make mutation breeding more targeted (Shu 2009;Wilde et al 2012). Molecular mutation breeding has been used to develop traits such as longer shelf-life (tomato, melon), improved starch quality (potato), and virus-resistance (peppers, tomato) which are being used in commercial varieties (Wilde et al 2012).…”

This book series provides complete, comprehensive and broad subject based reviews about existing biodiversity of different habitats and conservation strategies in the framework of different technologies, ecosystem diversity, and genetic diversity. The ways by which these resources are used with sustainable management and replenishment are also dealt with. The topics of interest include but are not restricted only to sustainable development of various ecosystems and conservation of hotspots, traditional methods and role of local people, threatened and endangered species, global climate change and effect on biodiversity, invasive species, impact of various activities on biodiversity, biodiversity conservation in sustaining livelihoods and reducing poverty, and technologies available and required. The books in this series will be useful to botanists, environmentalists, marine biologists, policy makers, conservationists, and NGOs working for environment protection.More information about this series at

“…Mutation breeding is a proven supplement and an effective substitute of conventional breeding so as to confer specific improvement in a variety without significantly affecting its acceptable phenotype (Sanjay Gandhi et al, 2014). Although selection for economically useful spontaneous mutants still takes place with some level of success (Wilde et al, 2012), the purposeful induction of a specifically desired mutation at a specific time and place, and in a selected genotype for a selected purpose is a much more attractive option. Induced mutation is a suitable source of producing variation through mutation breeding pro-cedure (Domingo et al, 2007).…”

Mungbean, (Vigna radiata (L.) Wilczek) occupies a unique position in Indian agriculture and has been grown under various agro-ecological conditions. It is cultivated in 1.61mha with production of 3.38MT and productivity of 474kg/ha in India. Mungbean pods are thin and brittle when dry, so shattering is a major problem. The loss of seeds by pod dehiscence is one of the major reasons for low yield in mungbean; thus, reducing the frequency of pod dehiscence is an important objective in mungbean breeding. Induced mutations, have offered a single and short alternative to conventional breeding including isolation, screening, selection and testing generation after generation. In this study, variability was induced by gamma rays and Ethyl methane sulphonate (EMS) in two greengram genotypes viz., CO (Gg) 7 and NM 65. Screening for pod shattering was carried out in M 2 and M 3 populations of greengram. The scoring for shattering was recorded at physiological maturity of the pod. The shattering percentage ranged from 14.56 (400 Gy) to 93.45 per cent (20 mM). A total of 100 shattering tolerant mutants were selected from field based on visual observation. These mutants were again scored under laboratory condition as per IITA method. A total of 12 mutants of CO (Gg) 7 and 10 mutants of NM 65 which were tolerant to pod shattering were identified in M 2 generation and forwarded to M 3 generation. These mutants were scored for pod shattering under laboratory condition and nine mutants viz., M26, M44, M46, M58, M70, M71, M84, M92 and M98 were found to be tolerant in M 3 generation. This study on identification and screening of the mutants tolerant to pod shattering with high yielding potential will help to increase the production of the pods to a greater extent.
