Relationship of physiological attributes with seed yield was assessed in 22 rice genotypes. Seed yield was significantly positively associated with NAR (0.3607), LAI (0.7968), Pn (0.9553), SLW (0.6906} and TDM (0.8833). Path coefficient analysis showed that TDM and Pn positive direct effect and positive indirect effects and were most important traits for increasing grain yield in rice.
