The present study was carried out at Seed Research and Technology Centre, PJTSAU, Rajendranagar, Hyderabad during 2019-20. Chemical traits like protein and ash contents of twenty five rice genotypes were assessed to know their effect on Sitophilus oryzae infestation. It was revealed that ash content had significant negative effect on mean adult emergence (-0.42) and per cent seed damage (-0.47), while it had significant positive effect with mean development period (0.41). On the other hand, protein content had significant positive relationship with mean adult emergence (0.44), per cent seed damage (0.42) and negative with mean developmental period (0.28).
