Crop yield is affected by low R/FR ratio of incident light which is characteristic of dense canopy. The R/FR ratio of incident light in turn interprets the status of canopy architecture and photoperiod length which is also amongst the most important information regulating crop yield. In addition to the information of light quality, quantity, direction, incidence plane, Phytochromes capture the information of R/FR ratio of incident light. There is little known about Phy regulation of crop yield in dense canopy. Our aim is to study the regulation of phytochrome signaling that may affect various yield components in rice. For this several megavarities, introgression lines and EMS mutants of rice are used. This study will help in designing strategies for engineering rice that are better adapted to dense canopy and unpredictable weather conditions with higher yield.
