Four single crosses, two double crosses, two open pollinated varieties and two composites were evaluated in a split-plot randomized block design with ten replications. Each plot comprised two sub-plots, one with plants spaced 20 cm (50,000 plants/ha) and the other with plants spaced 30 cm (33,333 plants/ha). The experiment was carried out mainly to evaluate the phenotypic variability of the treatment, considering the following characters: day to flowering , number of rows per ear, ears per plant, mumber of kernel grains per row, weight of 50 kernels, weight of ears and weight of grains per plant. Only competitive plants were considered. Phenotypic variability was estimated both in terms of standard desviation and also in term of coefficient of variation.In relation to population density all cultivars exhibited greater coefficient of variation at 50,000 plants/ha than at 33,333 plants/ha, for all characters except for ears per plant and days to flowering. In terms of standard desviation, in general the values were higher for the thinner population (33,333 plants/ha). In general, as expected, varieits had higher phenotypic variability than single crosses for all characters except for earsper plant. Varieties had lower coeefficient of variation than single crosses for ears per plant, weight of 50 kernels, weight of aers and weight of grains per plant. Varieties had greater phenotypic variation and standard desviations than double crosses for all characters except number of kernels per row. Relative (...)
