Cultivar x environment interactions for yield and several fruit traits were estimated from two groups of Virginia peanut (Arachis hypogaea L.) cultivar yield trials conducted in the Virginia-North Carolina production area.
A substantial cultivar x location x year second-order interaction was observed for yield in both studies. Both cultivar x location and cultivar x year interactions were small when compared to the variation among cultivars.
No advantage could be gained by subdividing the production area into subareas for breeding or testing purposes. However, a reallocation of the number of plots presently used could give comparable estimates of cultivar performance and reduce the time necessary for cultivar evaluation.
