ICRISAT in collaboration with Department of Biotechnology, Government of India and Generation Challenge Program (GCP – a programme of the CGIAR) has hosted the "2nd National Workshop on Marker-Assisted Selection (MAS) for Crop Improvement" during 27-29 October 2010, at ICRISAT Campus, Greater Hyderabad, India. The objective of this workshop was to create awareness among the crop breeding community in India about the latest developments in the field of marker assisted selection (MAS). For achieving this goal, the academic programme of the workshop also included presentations and discussions in the related fields of genomics, quantitative genetics and bioinformatics, that were relevant to a full discussion on MAS for crop improvement. The PIs/ Co- PIs/Collaborators of ongoing projects funded under the Accelerated Crop Improvement Programme (ACIP) of DBT and the senior scientists involved in evaluation and monitoring of these molecular breeding projects will participate in this workshop. Some senior scientists and experts both from India and abroad also joined as special invitees to deliberate on this important subject.

The development of DNA (or molecular) markers and their use has already made a major impact on the way we conduct research in the field of plant genetics and also on the selection strategies we use in plant breeding. During the last two decades, both interval mapping and association mapping have been successfully used to identify marker-trait associations (MTA) for a variety of traits in all major crops to facilitate the use of marker genotyping as a substitute for cumbersome phenotypic selection, particularly for the traits that are difficult to score visually. Techniques have also been developed to undertake 'background selection' to reconstitute the genome of recurrent parent after transfer of a desirable gene through backcross method of plant breeding. The marker assisted selection (MAS) has thus reached a stage, when it is already being used as an integral component of conventional plant breeding, leading in several crops to the development of improved cultivars/hybrids that are being grown by the farmers in different parts of the world. The techniques involved in MAS are also evolving further to make MAS cost-effective and to further accelerate the process of plant breeding. For instance, in addition to the routine marker-aided backcrossing (MABC), marker-assisted recurrent selection (MARS) and genome wide slection (GWS) are the two new approaches that are now being practiced to improve the efficiency and effectiveness of MAS. DNA sequencing-based genotyping has also emerged as a new approach due to the emerging new generation sequencing (NGS) technologies that would reduce the cost of whole genome sequencing by several orders.

It is thus obvious that recent advances in the areas of DNA sequencing, genotyping, bioinformatics and statistical genetics/genomics offer immense opportunities for the use of modern genetics for gene/QTL discovery and allele mining, thus transforming crop breeding approaches. A number of phenomics and molecular breeding platforms have also been developed to bring precision in working out marker-trait associations and their use for MAS. Therefore, plant breeders are at a threshold for a major transformation in the methods they use in conventional plant breeding; they need to equip themselves for using these modern genomics tools in their breeding programmes. The workshop has been planned to bring the leading scientists in the area of modern genomics and those involved in molecular breeding both from India and abroad. The deliberations and brainstorming sessions of this workshop should hopefully empower molecular breeding community in using modern genomics and breeding methodologies for crop improvement.

With an objective to share the experience and views of experts in the area of molecular breeding, we are providing the presentations made at this workshop. While these presentations are made freely available to everyone, you are requested to seek permission of the respective presenter/speaker, in case you may be required to use some of slides/figures, etc. and a proper citation (In: 2nd National Workshop on Marker-Assisted Selection for Crop Improvement, 27-29 October 2010, ICRISAT, Hyderabad, AP, India) should be given
