Multi-environment Analysis for Queensland Sites

摘要

SELECTIONS WERE EVALUATED over multiple sites because of the importance of genotype-by-environment interaction in genetic impiovement of peanuts. Therefore it is important to assess whether differences among selections are consistent across peanut production environments. The sample of environments used in the Queensland evaluation did not include all peanut production regions. Six of the seven sites were in the Burnett region of southern Queensland, where most of the Australian rain-fed peanut production occurs. The seventh site, at Karri in North Queensland, differs in latitude and altitude, but has a similar soil-type to the Burnett sites. Irrigation and planting date were used to create environmental variation among close trial sites at the Kingaroy research station in the Burnett.
