The absence of fissure between palea and lemma of the husk rice grain, is an important character to avoid infestation by insect plague on storage. In the current paper 14 genotypes of upland rice were evaluated in three places of Pernambuco state; Palmares, Vitória de Santo Antão and Carpina counties. It was used randomized complete block design with four replications and the evaluations were made using 250 grains from each plot. The statistical analyses were made by software Genes and the average was compared by Tukey test with 5% of probability. The genotype x environment interaction was significant for the three places and the genotype BRSMG curinga was one of the most resistant and the PB 5 was one of most susceptive and, the difference on loss potential between both genotypes varies from 24.10 to 44.75% on tree places. Therefore there was variability among genotypes for resistance furthermore there was high difference on the loss potential in case infestation by insect plague during grain storage.
