This book was released on 2013-03-14 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic variability is an important parameter for plant breeders in any con ventional crop improvement programme. Very often the desired variation is un available in the right combination, or simply does not exist at all. However, plant breeders have successfully recombined the desired genes from cultivated crop gerrnplasm and related wild species by sexual hybridization, and have been able to develop new cultivars with desirable agronomie traits, such as high yield, disease, pest, and drought resistance. So far, conventional breeding methods have managed to feed the world's ever-growing population. Continued population growth, no further scope of expanding arable land, soil degradation, environ mental pollution and global warrning are causes of concern to plant biologists and planners. Plant breeders are under continuous pressure to improve and develop new cultivars for sustainable food production. However, it takes several years to develop a new cultivar. Therefore, they have to look for new technologies, which could be combined with conventional methods to create more genetic variability, and reduce the time in developing new cultivars, with early-maturity, and improved yield. The first report on induced mutation of a gene by HJ. Muller in 1927 was a major mi1estone in enhancing variation, and also indicated the potential applica tions of mutagenesis in plant improvement. Radiation sources, such as X-rays, gamma rays and fast neutrons, and chemical mutagens (e. g. , ethyl methane sulphonate) have been widely used to induce mutations.

Download or read book Mutation Breeding in Chickpea written by IMRAN Kozgar and published by Walter de Gruyter GmbH & Co KG. This book was released on 2014-01-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book by M. Imran Kozgar aims to cover the problems of mutation breeding in pulse crops in the light of issues related to food insecurity and malnutrition, which according to FAO are the major threats at the present time. So far the research on induction of mutation in pulse crops is negligible compared to cereal crops, though the pulse crops and especially the chickpea are the largest grown crops in India. The main objective of the book is to reveal and explore the possibility of inducing genetic variability in early generations of mutated chickpea, describe the positive aspects of mutagenic treatments, evaluate the content of mineral elements (iron, manganese, zinc and copper) and physiological parameters of isolated high yielding mutant lines. The author hopes that his book will help to advance studies on pulse crops, and that in the long term it will help to reduce the food insecurity and malnutrition problems presently persisting in various developing countries, including India.

Download or read book Induced Mutations in Plant Breeding written by W. Gottschalk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mutation breeding has been introduced into modern plant breeding in the early 1940's. In spite of pessimistic predictions, the application of experimental mutagenesis has led to encouraging results demonstrating that mutation breeding is a well-functioning method in many crops. So far, more than 500 varieties, developed by means of induced mutations, have been officially released; others have been approved for registration. Many mutants with characters of agronomic interest cannot be utilized directly because of their unsatisfying yielding capacities, or of other negative traits which are partly due to the pleiotropic action of the mutant genes. Sometimes their negative selection value can be overcome by transferring them into the genomes of other varieties. According to experience available, the efficiency of mutant genes can conSiderably vary depending on the genotypic background in which they become effective. The interactions between mutant genes and genotypic back ground cannot be predicted. Therefore, mutants with valuable traits should be crossed with many varieties and strains in order to discern positive and negative interactions. In this way, genotypes can be selected in which the mutant gene is able to express its action without showing negative by-effects. This procedure has been used for about 10 years by combining the methods of mutation and crossbreeding. Mutation breeding is predominantly used in annual diploid and allo polyploid self-fertilizing crops, while it causes much more difficulties in cross-pollinating species.
Download or read book Systems for Cytogenetic Analysis in Vicia Faba L written by G.P. Chapman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike the situation in the major cereals, the yields of Vicia faba have not been markedly increased during the last half century. There is no single cause for this but among those that have been important is the lack of cytogenetic understanding in relation to breeding performance. Since as a consequence, little genetic variation has been available to agronomists conclusions, probably unwarranted, have been drawn about the limited prospects for the faba bean. Against such a background it has been difficult to justify the investment of research resources in the crop. The central theme of this book is that with the establishment of cytogenetic studies in Vicia faba understanding of its genetic system will develop in relation to breeding improvement and thereafter some at least, of the impediments to yield increase can steadily though not dramatically, be removed. We have distinguished between longer and shorter papers and only the former include Abstracts. The latter amplify themes in the longer papers or were written to develop particular topics at the request of the editors. G.P. Chapman S.A.

This book was released on 2023-04-04 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the recent progress on the applications of mutation breeding technology in crop plants. Plant breeders and agriculturists are faced with the new challenges of climate change, human population growth, and dwindling arable land and water resources which threaten to sustain food production worldwide. Genetic variation is the basis which plant breeders require to produce new and improved cultivars. The understanding of mutation induction and exploring its applications has paved the way for enhancing genetic variability for various plant and agronomic characters, and led to advances in gene discovery for various traits. Induced mutagenesis has played a significant role in crop improvement and currently, the technology has resulted in the development and release of more than 3600 mutant varieties in most of the crop plants with great economic impact. The field of ‘mutation breeding’ has come long way to become an important approach for crop improvement. This book covers various methodologies of mutation induction, screening of mutants, genome editing and genomics advances and mutant gene discovery. The book further discusses success stories in different countries and applications of mutation breeding in food crops, horticultural plants and plantation crops. This informative book is very useful to plant breeders, students and researchers in the field of agriculture, plant sciences, food science and genetics.
