A Review on Molecular Marker Analysis for Yield and its Component Traits under Water Stress and Zinc Deficiency Tolerance in Rice

The Wonder Cereal, Rice (Oryza sativa L.) is the heart of our culture and the staple food crop consumed by more than 50 per cent of the world’s population. Aerobic rice proves to be a viable technology by reducing water losses through seepage, percolation and evaporation. However, under aerobic condition several essential nutrients, especially zinc became unavailable due to positive soil redox potential. Therefore genetic improvement of rice genotypes for zinc deficiency under aerobic condition is essential to exploit the water saving potential of aerobic condition. Molecular markers augment conventional plant breeding for efficient and precise identification or selection of a trait of interest linked to them.
