Geneotype by environment integractions and resource allocation in final stage selection trials in the burdikin district

摘要

Data from routine final stage selection trials of the Burdekin Sugar Experiment Station's sugarcane breeding program were analysed to determine the nature and relative magnitude of genotype~* environment (G~*E) interactions, and their effects on the allocation of resources. Significant G~*E interactions, were detected and affected all measured traits. Variance components were used to estimate the relative magnitude of each G~*E component, with genotpe~*location crop-year > gentoype~*crop-year > genotype~*location.
