This study were performed with 12 popcorn hybrids. The experiment was arranged in a complete randomised block design with four replications over three locations. Three traits were analyzed, grain yield, popping expansion, and number of kernels per 10 g. ANOVA showed very significant influence of genotype, location and interaction of genotype x location (GxL), for all three traits. This points out that those traits are not influenced only by genetic factors, but also by environmental factors and the interaction of those two factors. Spearman's correlation coefficient was established between examined traits. All correlations were negative and non significant. Nevertheless, expecially correlation between grain yield and popping volume (rp-z=-0.10) indicated that hybrids with higher yield produced lower popping volumes. This once more concluded that breeding of popcorn is very complex process, for there is a necessity for high yielding and good popping quality hybrids.
