 ABSTRACT

The changing climate accompanied with cold temperature which unmasks itself as a devastating stress for most of the high yielding rice cultivars in twenty first century. The early growth stage which include germination, seedling formation get severely damaged by cold stress leading into crop failure or major yield loss. However, the genotypes grown in colder climates of high altitude and temperate regions have evolved themselves to avoid or survive cold stress in course of time. In order to achieve cold tolerance in high yielding rice, a thorough understanding of this tolerance mechanism at physiological, metabolic and genomic level is imperative. So, the present review on rice covers the cold damage evaluation, characterization, physiological response to stress and tolerance mechanism in brief.

Key words: Rice, Early stage, Seedling, Cold, Stress, Tolerance
