In the present era various international organizations, such as FAO, UNO, IAEA, FNCA, etc., have unanimously agreed that millions of people in both developing and developed countries are not only facing a shortage of food, but also non-availability of nutrients. The main reason put forward by these agencies is that there is less genetic diversity prevalent in the major crops, which has been further diminished since the inception of conventional plant breeding. Since the first decade of the last century the mutation breeding approach has been pivotal in enhancing the genetic diversity of crops, thereby enriching the genetic pool. ‘Mutagenesis: exploring genetic diversity of crops’ describes the latest achievements in mutation breeding, with a particular focus on the development of novel mutant varieties and F1 hybrids of crops highly superior to the parental ones. The book details experimental as well as literary studies of induced mutagenesis and its role in developing the new potent varieties. The book will be useful for agricultural policy making authorities in countries of agricultural importance, scientific researchers, breeders, teachers and students keen to use mutation breeding and to explore its hidden potential to secure food and nutrient availability for the growing world population.

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.

For centuries, crop improvement has served as the basis of food security of ever increasing human population. Though vast germplasm collections are available; their exploitation for crop improvement still depends upon efficient assessment of genetic diversity. Genetic variability is the key element in adaptation of plants to varying climates. While crops with narrow genetic diversity are vulnerable to stresses. The estimation of extent and pattern of genetic variability is a prerequisite for generating superior varieties. Genetic diversity analysis generates key information to dissect genetic variations in crop germplasm with the help of morphometrical, biochemical and molecular tools. Among these, DNA markers provide a reliable and detailed insight into the similarities and differences among crops. In this chapter, we discuss the applications of phenotypic and molecular markers to probe genetic divergence in crops and present case studies that describe the significance of these tools to characterize sorghum germplasm. Furthermore, we spotlight sorghum biodiversity exploration efforts worldwide and propose future directions.
