Genetic Parameters and Trait Associations in Wheat Under Drought and Low Nitrogen Conditions

Nitrogen
Drought and low nitrogen stress are the leading cause of low crop production and productivity worldwide. Developing drought-tolerant wheat germplasm resilient to low nitrogen conditions is essential through genetic enhancement and selection for novel ...

Variance Components, Correlation and Path Coefficient Analysis of Morpho-Physiological and Yield Related Traits in Spider Plant (Gynandropsis gynandra (L.) Briq.) under Water-Stress Conditions

Agronomy, 2023
Drought is the most complex abiotic stress for crop production at the global level. Therefore, developing new African spider plant genotypes tolerant to drought stress is one of the best approaches to achieving and optimizing high yield potential with ...

Non-homogeneity of variance components from spatially nested sampling of the soil

, 2009
Spatially nested sampling and the associated nested analysis of variance by spatial scale is a well-established methodology for the exploratory investigation of soil variation over multiple, disparate scales. The variance components that can be estimated

Variance components estimation of residual errors in GPS precise positioning [PDF]

Geodetski Vestnik, 2016
Variance components analysis of residual errors remaining in the GPS double-difference phase observations is presented in this paper. These errors arise due to unmodeled ionospheric, tropospheric and multipath effects and limit the accuracy of n ...

Variance components and nonlinearity [PDF]

, 2006
summary:Unknown parameters of the covariance matrix (variance components) of the observation vector in regression models are an unpleasant obstacle in a construction of the best estimator of the unknown parameters of the mean value of the observation ...
