SUMMARYWhen some treatments (checks) are replicated r times and other treatments (new treatments) are replicated less than r times, an augmented desigii may be used. These designs may be minimum variance designs for estimating contrasts of check effects, of new variety effects, of new variety versus checks, or of all check and new varieties simultaneously. In this paper optimal augmented block and optimal augmented row-column designs for estimating certain contrasts of new treatments are presented.

Needles: Toward Large-Scale Genomic Prediction with Marker-by-Environment Interaction

“…These so-called standards were replicated four times per environment, except for the simulation with the largest number of records, where they were replicated 10 times in each environment. As such, the simulation resembles a sort of augmented design (Federer and Raghavarao 1975), where the RIL genotypes that are not standards are tested in four different environments, except for the largest simulation, where they are tested in all (10) environments. To illustrate this with an example, consider a simulation with 1000 phenotypic records per environment and 50 environments in total.…”

Evaluation of experimental designs in durum wheat trials

“…Control treatments are used in these designs with replications in check plots, in order to evaluate the genetic material with no replications. More sophisticated Augmented designs allow for the adjustment of test varieties by rows and columns (Federer and Raghavarao, 1975;Lin and Poushinsky, 1983). In these designs, each test variety is surrounded by two, three, or four check plots.…”

Delineamento em blocos casualizados completos aumentados

“…Delineamento aumentado ê um tipo de delineamen to experimental formado a partir de qualquer delineamento, pelo acréscimo de parcelas nos blocos Foi introduzido por FEDERER (1956), no Havaí, com o objetivo de solucionar problemas encontrados ao comparar plântulas ("seedlings") e "variedades" (que melhor se chamariam clones) de cana-de-açücar. GOMES & GUIMARÃES (1958), observa-se que ha uma certa semelhança entre eles, onde cada bloco do delineamento aumentado corresponde a um experimento em blocos casualizados com pletos, considerado sem repetição.…”
