plrv

<p>resistance study to PLRV (Patato Leaf Roll Virus) causing leaf
curl. 28 genotypes were experimented at 6 locations in Peru. Each clone was
evaluated three times in each environment, and yield, plant weight and plot were
registered.</p>

datasets

Data from multi environment agronomic trials, which are often
carried out by plant breeders, can be analyzed with the tools offered by this
package such as the Additive Main effects and Multiplicative Interaction model
or 'AMMI' ('Gauch' 1992, ISBN:9780444892409)
and the Site Regression model or 'SREG' ('Cornelius' 1996,
<doi:10.1201/9780367802226>). Since these methods present a poor performance
under the presence of outliers and missing values, this package includes
robust versions of the 'AMMI' model ('Rodrigues' 2016,
<doi:10.1093/bioinformatics/btv533>), and also imputation techniques
specifically developed for this kind of data ('Arciniegas-Alarcón' 2014,
<doi:10.2478/bile-2014-0006>).
