1.4 screening experimental designs for quantitative trait loci, association mapping, genotype-by environment interaction, and other investigations
Crop breeding programs using conventional approaches, as well as new biotechnological tools, rely heavily on data resulting from the evaluation of genotypes in different environmental conditions (agronomic practices, ...
From genotype x environment interaction to gene x environment interaction
Historically in plant breeding a large number of statistical models has been developed and used for studying genotype x environment interaction. These models have helped plant breeders to assess the stability of economically ...
A general Bayesian estimation method of linear-bilinear models applied to plant breeding trials with genotype × environment interaction
Statistical analyses of two-way tables with interaction arise in many different fields of research. This study proposes the von Mises?Fisher distribution as a prior on the set of orthogonal matrices in a linear?bilinear ...
Evaluation of three field-based methods for quantifying soil carbon
Three advanced technologies to measure soil carbon (C) density (g C m−2) are deployed in the field and the results compared against those obtained by the dry combustion (DC) method. The advanced methods are: a) Laser ...
Phylogenetic and multivariate analyses to determine the effects of different tillage and residue management practices on soil bacterial communities
Bacterial communities are important not only in the cycling of organic compounds but also in maintaining ecosystems. Specific bacterial groups can be affected as a result of changes in environmental conditions caused by ...
Narrowing the agronomic yield gap with improved nitrogen use efficiency: A modeling approach
Improving nitrogen use efficiency (NUE) in the major cereals is critical for more sustainable nitrogen use in high-input agriculture, but our understanding of the potential for NUE improvement is limited by a paucity of ...
