Cereals make an important component of daily diet of a major section of human population, so that their survival mainly depends on the cereal grain production, which should match the burgeoning human population. Due to painstaking efforts of plant breeders and geneticists, at the global level, cereal production in the past witnessed a steady growth. However, the cereal production in the past has been achieved through the use of high yielding varieties, which have a heavy demand of inputs in the form of chemical fertilizers, herbicides and insecticides/pesticides, leading to environmental degradation. In view of this, while increasing cereal production, one also needs to keep in mind that agronomic practices used for realizing high productivity do not adversely affect the environment. Improvement in cereal production in the past was also achieved through the use of alien genetic variation available in the wild relatives of these cereals, so that conservation and sustainable use of genetic resources is another important area, which is currently receiving the attention of plant breeders. The work leading to increased cereal production in the past received strong support from basic research on understanding the cereal genomes, which need to be manipulated to yield more from low inputs without any adverse effects as above. Through these basic studies, it also became fairly apparent that the genomes of all cereals are related and were derived from the same lineage, million of years ago.

Over de auteur
This book is the first of its kind, where twenty chapters written by experts of international repute, cover all aspects of cereal genomics research. In recent years genomics has become a thrust area of research in life sciences, and cereals, being the most important group of crops, their genomes have been subjected to intensive/extensive analyses. The knowledge and the products generated through cereal genomics research are already being used for plant breeding through both, the marker assisted selection (MAS) and transgenic cereals. The areas covered in this book include, development and use of all kinds of molecular markers (including SNPs), construction and use of molecular maps, study of population genetics and domestication of cereals using tools of genomics research, structural and functional genomics (including whole genome sequencing in Arabidopsis and rice), comparative genomics, QTLs (including epistatic and e-QTLs) and genes for resistance against biotic and abiotic stresses, marker assisted selection (MAS), map-based cloning of genes/QTLs and the use of genomics research for crop improvement. The book, therefore, should prove useful not only for students and teachers, but also for the young research workers, who are starting their research career in the field of cereal genomics.
