Abstract

Synopsis This investigation revealed both the top cross tester parents and the segregating population influenced considerably the measurement of combining ability, but the different tester parents gave about the same relative information on lodging and ear height. The study also indicated that some single crosses were equally as effective as double crosses for measuring general combining ability.
