Resumo

The aim of this work was to evaluate the morphological traits of the grains of upland rice genotypes and indicate genotypes with grains with characteristics that are preferable by rice consumers. The experiment was carried out in randomized blocks, with 42 upland rice genotypes and 4 replications, totaling 168 experimental plots. After harvest time, the following parameters were determined with digital caliper in a sample of 20 paddy rice grains per plot: GW= grain width (greater side dimension), GT= grain trickness (smallest side dimension), GL= grain length (distance between extremities) and GLGW= length-to-width ratio. The data were first submitted to the F-test (p<0.05) and, subsequently, to the Scott-Knott multiple comparison test at p<0.01 and p<0.05. The genotypes OSVR15029, OSVR15031 and OSVR15032 presented values ​​of length greater than 6.0 mm, thickness less than or equal to 1.90 and length-to-width ratio greater than 2.75, interesting characteristics for the long and fine grain consumer market.
