Synopsis Lines selected for specific combining ability were found to represent a random sample with respect to general combining ability when compared with an unselected group of lines from the same original source using a broad gene base tester. The data support the common practice of testing new lines first for general combining ability, followed by tests for specific combining ability. Population improvement was greater when selection was based on a broad gene base tester.
