Genomic-enabled prediction of ordinal data with bayesian logistic ordinal reg... N3 | TTL | RDF/XML | JSON-LD
CIMMYT EthiopiaMost genomic-enabled prediction models developed so far assume that the response variable is continuous and normally distributed. The exception is the probit model developed for ordered categorical phenotypes. In statistical applications, due to the easy implementation of the Bayesian probit ordinal regression (BPOR) model, Bayesian logistic ordinal...Created January 20, 2025 • Updated January 20, 2025 -
CIMMYT Maize Lines (CMLs) - Pedigree and characterization data N3 | TTL | RDF/XML | JSON-LD
CIMMYT EthiopiaCIMMYT has periodically announced CIMMYT Maize Lines (CMLs). CMLs are carefully selected inbred lines with good general combining ability and a significant number of value-adding traits such as drought tolerance, N use efficiency, acid soil tolerance, resistance to diseases, insects and parasitic weeds. In many instances, they are parental lines of...Created January 20, 2025 • Updated January 20, 2025 -
SI-SAS. A SAS Code to Calculate Several Selection Indexes N3 | TTL | RDF/XML | JSON-LD
CIMMYT EthiopiaSI-SAS is a code written in SAS to produce several selection indexes. To run the code you have to have SAS 9.2 or higher installed in your computer. The first task is to change the folder where the data file to analyze is located and the name of the file. The data file must be in csv format with columns for variables and rows for observations.

Selection of the bandwidth parameter in a bayesian kernel regression model fo... N3 | TTL | RDF/XML | JSON-LD
CIMMYT EthiopiaOne of the most widely used kernel functions in genomic-enabled prediction is the Gaussian kernel. Usually selection of the bandwidth parameter for kernel regression is based on cross-validation. In this study, we propose a Bayesian method for selecting the bandwidth parameter h of a Gaussian kernel as the mode of its posterior distribution. We present a...Created January 20, 2025 • Updated January 20, 2025 -

CIMMYT EthiopiaThe marker × environment interaction (M×E) genomic model can be used to generate predictions for untested individuals and identify genomic regions whose effects are stable across environments and others that show environmental specificity. The objectives of this study were: (1) to extend the M×E interaction model using priors that produce shrinkage and...Created January 20, 2025 • Updated January 20, 2025 -

Application of a genomics selection index to real and simulated data N3 | TTL | RDF/XML | JSON-LD
CIMMYT EthiopiaWe apply a Genomic Selection Index (GSI) to simulated and real data sets with four traits and numerically we compared its efficiency with that of the phenotypic selection index (PSI) using the ratio of the GSI response over the PSI response. In addition, we used two additional criteria to compare the GSI vs PSI efficiency: the ratio of the average of the...Created January 20, 2025 • Updated January 20, 2025 -
