Abstract
Inbreeding effects on five characteristics of two Zea mays varieties were estimated. Seven inbred subpopulations, ranging from F = O to 9/16, of each variety were obtained by using double-double (8-line) pedigrees. Environmental error and genotype-by-environment interaction components of variance were not significantly affected by the level of inbreeding. The regression of performance on expected inbreeding was linear for yield, number of days to tassel, ear height, and plant height. If epistatic effects are contributing to the variability in these two populations they must be of the type which lead to a linear relationship between average performance and inbreeding. Inbred progenies derived from sets of inbred lines were analyzed separately. Variability in response to inbreeding among such sets of genetic material was detected
