Epistasis in pearl millet, Pennisetum typhoides (Burm.) Stapf and C. E. Hubb., forage yields was detected (by Bauman's method) in 16 of 33 two-year tests involving the six possible sets from selected pearl millet inbreds 13, 18, 23, and 26. Parents, testers, and environment influenced the amount of epistasis observed. The three inbred tester combinations that gave significant positive deviations in one year and significant negative deviations in the other indicated the important role of environment in the expression of epistasis. In another 2-year forage production test of the parents, F1's, and F2's of a nineinbred diallel, five F2 hybrids demonstrated the presence of epistasis when they deviated significantly from expected yields (P1 + P2 + 2F1/4
