Abstract

Twelve cultivars were evaluated for grain yield in two trials, harvested 9-14 days apart, at ten localities in 1979 and in one trial at nine localities in 1980. In 1979, the cultivar X locality interaction was significant, but the cultivar X harvest date within-locality interaction was not. Over all 29 environments, the cultivar X environment interaction was significant. In orthogonal sets of five localities and two years, the cultivar X year X locality interactions were significant, while cultivar X year and cultivar X locality interactions generally were not. Pattern analysis showed that cultivars of dissimilar genetic origin had different yield responses across environments. An environmental classification based on cultivar X environment interactions indicated that there were no temporal or closely related regional environment groups with similar cultivar X environmental interactions. It is concluded that lower critical percentage differences between new and established cultivars in prerelease trials can be obtained by adding environments, rather than replicates
