Abstract

The present study highlights the effect of temperature rise on crop growth and productivity. Improving crop resilience to temperature stress is a vital step towards ensuring global food and fuel demands are met. Temperature is a critical meteorological determinant of crop development and function. Essential physiological processes including carbon assimilation and leaf chlorophyll content are very sensitive to high temperature extremes. High-temperature stress occurs when morpho-physiological and biochemical attributes of plant development are altered. Flowering optimum temperature was 25-30 °C. higher temperature (both max. and min.) and low diurnal variation in temperature are more conducive for early flowering rice variety. Advances in molecular techniques now allow for swift identification of beneficial traits in wild varieties. It is crucial to adopt advanced agricultural practices worldwide to mitigate the impact of rising global temperatures. This includes implementing climate-smart strategies and employing high-throughput phenotyping  methods to identify and utilize resilient traits, thereby safeguarding future food security.
