This edited volume reviews the current status and trends in research of different field crops. Individual chapters cover anther and microscope culture, protoplast culture and fusion somaclonal variation and induced mutations in relation to crop improvement. A few chapters describe technologies such as Agrobacterium mediated and particle bombardment genetic transformation. Additional chapters deal with the important aspects of gene stability in transgenics and disease resistance genes for improved yield. This book also contains well-thoughout discussions on GM food Production.
