A field study was undertaken to understand the effect of low light in Rice involving the cultures and four cultivars. Light stress was found to decrease total biomass, yield and yield components. The reduction in the ultimate grain yield was found to be affected due to the increased number of ill‐filled spikelets. Low light tolerant varieties viz., IET 10436, IET 11058, Ponni and Bhavani were found to withstand the light stress and recorded nominal yield by maintaining minimal reduction in all the desired parameters.
