Análise de Cluster e Bootstrap no estudo da interação genótipo x ambiente

Abstract

Agricultural experimentation is a statistical technique that is becoming more and more recognized and used since there is a need to produce more food in less time=space. Studies show that the interaction between genotypes and environments is important in this type of analysis, because there are genotypes that are favored in certain environments, which brings an increase in the production of these genotypes. In this paper we will present the use of an agricultural experimentation technique called AMMI (additive main e ects and multiplicative interaction model) whose objective is to analyze the interaction between genotypes and environments using the Bootstrap method to make a resampling of the data and obtain more accurate information. In addition to the AMMI analysis, a Cluster analysis will be performed to verify if the environments that are divided into regions are homogeneous within the groups and heterogeneous among them.
