The book offers an indispensable journey into the intricate world of genetic principles and their profound implications for agricultural enhancement. Beginning with foundational topics, such as Genetics, Inheritance, and Variation, the book meticulously lays the groundwork for comprehending how traits manifest and evolve within plant species. It delves deep into the molecular mechanisms of inheritance through Genes, Cytogenetics, and Biometrical Genetics, illuminating the intricate pathways through which genetic information shapes the characteristics of crops across generations. Beyond the basics, this volume delves into specialized areas crucial to modern crop breeding. Chapters on Sex Determination, Linkage and Linkage Mapping, and Exceptions to Mendelism unravel the complexities of genetic interactions and inheritance patterns that underpin strategic breeding approaches. Discussions on Quantitative Inheritance and Multiple Allelism provide nuanced insights into the inheritance of traits crucial for optimizing crop yields and quality. Moreover, this book seamlessly integrates theoretical knowledge with practical applications. It explores the molecular foundations of genetics in chapters dedicated to DNA, Population Genetics, and Mutation, offering readers a comprehensive grasp of genetic diversity and variability within plant populations. Evolutionary insights explored in Evolution and Speciation highlight the dynamic interplay between genetic adaptation and agricultural progress. Ethical dimensions, as discussed in the chapter on Eugenics, prompt critical reflections on the responsible application of genetic advancements in agricultural contexts. This meticulously crafted volume caters to students, researchers, and practitioners alike, offering a rich tapestry of knowledge essential for advancing agricultural sciences through informed genetic research and innovative crop improvement strategies.
