Abstract
A diallel cross involving five noninbred (purebred) lines of Japanese quail indicated that additive and nonadditive genetic effects had important influences on behaviors involved in a detour learning task. Social isolation for 3 hr was used to provide additional motivation which enabled detection of differences among strains. The percentage of quail, within purebred lines, that solved a 4-min detour task three or more consecutive times ranged from 52 to 72. Differences among purebreds were significant for most of the components of the learning task. Further, the data suggested strain differences associated with the successful attainment of the desired goal when there was a similar level of general activity.
