ABSTRACT

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.
