Abstract
A total of 72 groundnut (Arachis hypogaea) lines in the F4 and F5 generations, representing 8 F3 families from each of 9 crosses, were evaluated for yield and 5 yield components at Lewiston, North Carolina and Suffolk, Virginia during 1977-78. Significant differences for all traits occurred among cross populations and among lines within populations. Crosses interacted with the environment for all traits, while lines within crosses interacted with the environment for all traits except yield. The crosses interacted with the environment because their rankings of performance changed in the different environments. In spite of a significant cross × environment interaction, the three best performing cross populations were identified as being high yielding at both locations. An examination of genetic components of variance for crosses and lines within crosses for the different environments indicated that superior crosses could be identified at a single location. However, individual lines within crosses should be selected on mean performance across environments (years and locations)
