| The perennial plant selection is based on individual genetic values predicted from phenotypic observations. The more adequate the control of environmental variability, the more accurate the prediction. This paper aimed to investigate: 1) the test ability by using the significance of Snedecor F test for block effects; 2) the spatial variability within blocks by using the plot intraclass correlation coefficient; 3) the experimental design efficiency in terms of the local control, by using the significance of Snedecor F test for block effects and the plot intraclass correlation coefficient (c2), simultaneously; 4) the genotype x environmental interaction within site, by using the genetic correlation coefficient across replications. The used data... |
