Conteúdo:	The objective of this work was to verify the uniformity of lots of rice seeds Oryza sativa ., cv. BR IRGA 409, by the heterogencity test. Eight lots of size 1-50-100, 101-150, 151-200, 201-250, 251-300, 301-350 and 351-40 bags were used, being submited to the sampling intensities of 17, 25, 30, 40, 50, 60, 70 and 80 bags, respectively. The attributes tested were physical purity percentage, number of red and blasck rice seeds, number of delulled seeds, germination percentage and number of normal seedlings verified in the cold test. The results obtained allowed the following conclusions to be drawn: the lots up to 100 bags of rice seeds showed high uniformity; independently of the lot sizes and sampling intensities, the values of (H) did not show significant heterogencity for the attributes studied, and the modified cold test was the best attribute for the determination of rice seed heterogeneity.
