Statistical models that capture the phenotypic plasticity of a genotype across environments are crucial in plant breeding programs to potentially identify parents, generate ofspring, and obtain highly productive genotypes for target environments. In this study, our aim is to leverage concepts of Bayesian models and probability methods of stability analysis to untangle genotype-by-environment interaction (GEI). The proposed method employs the posterior distribution obtained with the NoU-Turn sampler algorithm to get Hamiltonian Monte Carlo estimates of adaptation and stability probabilities. We applied the proposed models in two empirical tropical datasets. Our fndings provide a basis to enhance our ability to consider the uncertainty of cultivar recommendation for global or specifc adaptation. We further demonstrate that probability methods of stability analysis in a Bayesian framework are a powerful tool for unraveling GEI given a defned intensity of selection that results in a more informed decision-making process toward cultivar recommendation in multi-environment trials. |

Phosphorus is one among several factors which affects N2 fixation, and besides N, a principal yield-limiting nutrient in many regions of the world. Since the host plant is an essential partner in symbiosis, knowledge of host genotypic variability for N2 fixation at different levels of P availability will be useful when breeding cultivars for enhanced N2 fixation. The objective of this study was to investigate the possibility of obtaining common bean (Phaseolus vulgaris L.) lines which can fix large amounts of N2 under different levels of available phosphorus. Experiments were conducted in a growth room using a sand-alumina system which was reproducible and well suited for studying N2 fixation under different levels of available P and in the field where a low-Nsoil was chosen. In the growth room studies, P availability strongly affected plant growth and traits related to N2 fixation. However, no beneficial response was detected on the growth of the 14 common bean lines with addition of mycorrhiza. Competition for P between nodules and pods was observed at latter stages of growth, although other factors also contributed to a decline in nitrogenase activity and reduced nodule dry weight during the reproductive stage. Nodules were the plant part richest in phosphorus, and nodule dry weight was affected more than nodule number by limiting P supply, perhaps indicating that growth of the nodules was the primary factor limiting N2 fixation at low P levels. Generally no significant interaction was detected for P levels.....
