Genomic selection (GS) emphasizes the simultaneous prediction of the genetic effects of thousands of scattered markers over the genome. Several statistical methodologies have been used in GS for the prediction of genetic merit. In general, such methodologies require certain assumptions about the data, such as the normality of the distribution of phenotypic values. To circumvent the non-normality of phenotypic values, the literature suggests the use of Bayesian Generalized Linear Regression (GBLASSO). Another alternative is the models based on machine learning, represented by methodologies such as Artificial Neural Networks (ANN), Decision Trees (DT) and related possible refinements such as Bagging, Random Forest and Boosting. This study aimed to use DT and its refinements for predicting resistance to orange rust in Arabica coffee. Additionally, DT and its refinements were used to identify the importance of markers related to the characteristic of interest. The results were compared with those from GBLASSO and ANN. Data on coffee rust resistance of 245 Arabica coffee plants genotyped for 137 markers were used. The DT refinements presented equal or inferior values of Apparent Error Rate compared to those obtained by DT, GBLASSO, and ANN. Moreover, DT refinements were able to identify important markers for the characteristic of interest. Out of 14 of the most important markers analyzed in each methodology, 9.3 markers on average were in regions of quantitative trait loci (QTLs) related to resistance to disease listed in the literature.

Título em português: Genetic similarity between quince cultivars evaluated by AFLP markers. |
Conteúdo: |
O objetivo deste trabalho foi determinar as relações genéticas de 21 cultivares de marmeleiro com base no marcador ?amplified fragment length polymorphism? (AFLP), para melhoramento e conservação de recursos genéticos da espécie na região sul do Rio Grande do Sul. O DNA das cultivares foi extraído pelo método CTAB, e as reações de AFLP foram realizadas com os iniciadores EcoRI/MseI. Foram identificados dois grupos entre as 21 cultivares de marmeleiro, um com quatro e outro com sete cultivares geneticamente mais relacionadas. As cultivares de marmeleiro apresentam alta variabilidade genética, com máximo de 43% de similaridade. |
