Plant genetics and plant breeding are rapidly expanding areas. The two main ways of genetically modifying plants are gene gun method and agrobacterium method. New scientific advances in the field of genetics are exploring new frontiers in plant breeding. Crops are genetically modified for various reasons such as to increase yield, develop resistance towards pathogens, etc. Different approaches, evaluations, methodologies and advanced studies on plant genetics have been included in this book. It aims to serve as a resource guide for students and experts alike and contribute to the growth of the discipline.
