Abstract
Data of both early-and late-maturity groups from the Georgia peanut (Arachis hypogaea L.) variety trails under irrigated and non-irrigated management at two locations in 1975 and 1976 were used to estimate the magnitude of the variety x environment interaction of pod yield, %TSMK, %OK, %DK, %TK, %ELK, %Fancy and g/100 seed. Irrigation treatments caused marked responses of varieties and interaction effects for some of these traits. Both first-and second-order interactions varied under different treatments and for different traits. The significant varieties x locations x years interaction in most traits examined indicated that the varieties x years interaction varied with location. The relatively small values for varieties x location and for varieties x years indicate that there were no consistent location or year effects on differential varietal response for most of those traits during this period of testing. However, results indicate that the variety component significantly exceeded the first-and the second-order interactions and suggest that the varietal effect would be consistently present, especially for pod yield and size factors (g/100 seed, %Fancy and %ELK)
