Please can you give us a short summary of your article, ‘Genetic molecular markers to accelerate genetic gains in crops’? Accelerating and delivering genetic gains in smallholder farmers’ fields is high on international agricultural research agenda, especially in Asia and sub-Saharan Africa. This will help in improving crop productivity, better yield and higher income for farmers and most importantly achieving food and nutrition security in developing countries. Conventional plant breeding approaches have contributed immensely to this; however, they have limitations in terms of delivering improved varieties with desired traits in a time-bound manner. Genomics tools and technologies have changed methods of plant breeding in a positive direction. Since the boom of the genomic sequencing era, several advancements and innovations originating in the field of molecular markers are enhancing the pace of crop improvement. Over the decades, significant advances have been made in development of molecular markers article, we provide an update on the evolution of marker technologies and new applications for accelerating genetic gains in crop breeding programs. What led you to carry out this work? The crop productivity in several semi-arid tropic legume crops such as chickpea, pigeonpea and groundnut, has remained low for the last several decades. Genomics- assisted breeding or translational genomics approaches, due to limited availability of genomic resources, have not been used until recently in several of these crops.
