Sample size for full-sib family evaluation in sugarcane PAB
Leite,Mauro Sergio de Oliveira; Peternelli,Luiz Alexandre; Barbosa,Márcio Henrique Pereira; Cecon,Paulo Roberto; Cruz,Cosme Damião.
The objective of this study was to determine the minimum number of plants per plot that must be sampled in experiments with sugarcane (Saccharum officinarum) full-sib families in order to provide an effective estimation of genetic and phenotypic parameters of yield-related traits. The data were collected in a randomized complete block design with 18 sugarcane full-sib families and 6 replicates, with 20 plants per plot. The sample size was determined using resampling techniques with replacement, followed by an estimation of genetic and phenotypic parameters. Sample-size estimates varied according to the evaluated parameter and trait. The resampling method permits an efficient comparison of the sample-size effects on the estimation of genetic and phenotypic...
