In order to identify popcorn cultivars that constitute a viable alternative for popcorn producers, an experiment was conducted using a randomized blocks experimental design with five genotypes (BRS Ângela, Zélia, IAC 112, IAC 12 and IAC TC-01) and four repetitions, during the 2003/2004 crop. The experiment was carried out with 60 cm spacing between lines and density of 75 thousand plants per hectare. During the experiment, agronomic and commercial characteristics were evaluated, under field and laboratory conditions. The variety BRS Ângela featured increased yield, followed by simple hybrids IAC, with Zélia (triple hybrid) showing lower yield. The simple hybrid IAC 12 showed the lowest commercial quality of popcorn. Grain production was positively associated with the number of grains per ear and with the weigh of 1,000 grains, and negatively with the level of Ntotal in grain. The commercial quality was negatively influenced by the weigh of 1,000 grains.
