Agricultural genetics is the applied study of the effects of genetic variation and selection used to propagate valuable heritable trait combinations in crop plants. The discipline includes use of genetic markers to guide traditional breeding, and introduction of traits from other species. Agricultural genetics resources describes some lessons learned, over the last decade, of how genetically engineered crops have been integrated into agricultural practices around the world and discuss their current and future contribution to sustainable agricultural systems. This book deals with advance practices in molecular and genetic analysis of abiotic stress resistance of forage crops, genetic transformation of immature sorghum inflorescence via microprojectile bombardment and genetic and molecular aspects of plant response to drought in annual crop species. It explores statistical tools in measuring genetic diversity for crop improvement, genetic diversity of seed orchard crops and aflatoxins biochemistry and molecular biology. Some of the diverse topics covered in this book address the varied branches that fall under this category. This brings forth some of the most innovative concepts and elucidates the unexplored aspects of crop genetics. For all readers who all are interested in the field of agricultural genetics, the case studies included in this book will serve as an excellent guide to develop comprehensive understanding.
