Modelos estadísticos multiplicativos para el análisis de la interacción genotipo x ambiente
En los últimos 1O años se han logrado avances importantes en el uso de los modelos estadísticos multiplicativos para el análisis de ensayos de genotipos en ambientes múltiples y el estudio del complicado fenómeno de la ...
El análisis AMMI y la gráfica del biplot en SAS
En este documento se presentan tres ejemplos de casos en los que se emplearon programas creados en SAS para obtener Modelos AMMI, asi como la prueba de Gollob (Gollob, 1967) para determinar la significancia de cada termino ...
Data analysis in the CIMMYT applied biotechnology center: for fingerprinting and genetic diversity studies
The molecular genetic characterization of the diversity present in the CIMMYT maize and wheat germplasm collections is an ongoing process, to which many different persons have contributed. Furthermore, one of the mandates ...
User's manual for the LCDMV software (calculation software of molecular distances between varieties): for fingerprinting and genetic diversity studies
LCDMV (in English, known as the Calculation Software of Molecular Distances between Varieties) is a computer program developed in the SAS language (SAS Institute Inc., version 6.12), with the help of the modules SAS-STAT, ...
SAS macro for analysing unreplicated designs
Augmented or unreplicated experiment designs have two type of treatments, the replicated checks and the unreplicated new entries. The latter are usually considered to be random effects while the checks treatments are ...
Effect of leaf rust on grain yield and yield traits of durum wheats with race-specific and slow-rusting resistance to leaf rust
(American Phytopathological Society (APS), 2006)
Leaf rust, caused by Puccinia triticina, is an important disease of durum wheat (Triticum turgidum) in many countries. We compared the effectiveness of different types of resistance in International Maize and Wheat Improvement ...
A multi-trait multi-environment QTL mixed model with an application to drought and nitrogen stress trials in maize ( Zea mays L.)
Despite QTL mapping being a routine procedure in plant breeding, approaches that fully exploit data from multi-trait multi-environment (MTME) trials are limited. Mixed models have been proposed both for multi-trait QTL ...
Results of the 2008 regional and on-farm maize trials in West Africa
The DTMA project employs multi-location trials as vehicles for identification of drought tolerant varieties and hybrids with broad adaptation to a particular agro-ecological zone. Promising varieties selected based on trial ...
Dimensions of diversity in CIMMYT bread wheat from 1965 to 2000
To the extent possible, this paper summarizes scientific evidence on the scope of the genetic base in modern bread wheat varieties in the developing world from 1965 to the present, drawing on previously published research ...
Core Hunter: an algorithm for sampling genetic resources based on multiple genetic measures
(BioMed Central, 2009)
Background: Existing algorithms and methods for forming diverse core subsets currently address either allele representativeness (breeder's preference) or allele richness (taxonomist's preference). The main objective of ...
