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 ...
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 ...
Global crop improvement networks to bridge technology gaps
To ensure future food security, there is an urgent need for improved co-ordination of agricultural research. While advances in biotechnology hold considerable promise, significant technology gaps exist that may reduce their ...
Responding to the challenges of impact assessment of participatory research and gender analysis
Since the Green Revolution, the public-sector's agricultural research strategy for increasing food crop productivity has been explicitly based on the premise that technology can cross political and agro-climatic boundaries, ...
Number of kernels in wheat crops and the influence of solar radiation and temperature
The number of kernels per m2 (X) in well managed and watered wheat crops was studied using results of experiments in Mexico and Australia in which short spring wheat cultivars were subjected to independent variation in ...
