Description
Summary:Globally pearl millet production is severely hampered by low moisture stress during crop season affecting economic yield drastically especially in the dry ecologies. Though conventional genetic interventions have delivered drought tolerant varieties/hybrids but achieved limited success in drought prone ecologies. Next-generation breeding techniques have revolutionized improvement of genetically complex traits like drought. An efficient strategy is to integrate conventional breeding methodologies with ‘OMICS’ techniques for fast track identification and transfer of genes improving drought tolerance in pearl millet at critical growth stages. Recently published draft genome sequence of pearl millet have made available a large wealth of genomic information and resources which could speed up breeding programmes for enhancing drought tolerance. The review highlights the multifarious effects of low moisture stress at different phases in pearl millet and mechanisms to cope with it. Progress made so far in tackling drought stress through conventional and next generation enabled breeding techniques has been discussed highlighting on an integrated OMICS approach to address drought stress effectively.
