STUDIES ON RICE VARIETIES FOR RESISTANCE TO THE MAIZE WEEVIL,SITOPHLUS ZEAMAIS MOTSCHULSKY IN STORED GRAIN

This paper deals with the resistance of rice variety to the maize weevil. Of the 53 rice varieties tested, 39 exhibited resistant and three moderately resistant. The resistance that was evaluated on the basis of no-choice screening test had the same trend as that based on free choice screening test Highly significant positive correlation (P<0. 001) existed between susceptibility index and percentage Of gaping glumes.No corrlation (P>0. 05) between protein, starch, amylopectin, amylose content, gelatinization temperature and susceptibility index was demonstrated.
