Prospects of GWAS and predictive breeding for European winter wheat’s grain protein content, grain starch content, and grain hardness

Predicting Grain Protein Content of Winter Wheat

The objective of this paper is to propose to use a new Improved Particle Filtering (IPF) based on minimizing Kullback-Leibler divergence for crop models' predictions. The performances of the method are compared with those of the conventional Particle Filtering (PF) at a complex crop model (AZODYN) to predict an important winter-wheat quality criterion, namely the grain protein content. Furtherm...

Effect of urea foliar feeding on grain protein content and quality in two winter wheat cultivars

Relating satellite imagery with grain protein content

Satellite images, captured during the growing seasons of barley, sorghum and wheat were analysed to establish a relationship between the spectral response and the harvested grain protein content. This study was conducted near Jimbour (approx. 151°10’E and 27°05’S) in southern Queensland. Grain protein contents of the geo-referenced samples, collected manually during the harvest, were determined...

Predicting Biomass and Grain Protein Content Using Bayesian Methods

This paper deals with the problem of predicting biomass and grain protein content using Improved Particle Filtering (IPF) based on minimizing Kullback-Leibler divergence. The performances of improved particle filtering are compared with those of the conventional Particle Filtering (PF) in two comparative studies. In the first one, we apply IPF and PF at a simple dynamic crop model with the aim ...

Impact of Wheat Grain Selenium Content Variation

Cereal Chem. 88(2):195–200 Selenium (Se) is an essential micronutrient in animals. High levels of Se can accumulate in wheat grain, but it is not clear how high Se affects milling or baking. Low and high Se grain from the same hard red winter wheat cultivar was milled and used for breadbaking studies and Se analysis. Mill stream yields from the low and high Se wheat were comparable, as were flo...
