New genetic resources in wheat breeding for an increased grain protein content

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

The Genetic Control of Grain Protein Content under Variable Nitrogen Supply in an Australian Wheat Mapping Population

Genetic variation has been observed in both protein concentration in wheat grain and total protein content (protein yield). Here we describe the genetic analysis of variation for grain protein in response to nitrogen (N) supply and locate significant genomic regions controlling grain protein components in a spring wheat population. In total, six N use efficiency (NUE) field trials were carried ...

Breeding Value of Primary Synthetic Wheat Genotypes for Grain Yield

To introduce new genetic diversity into the bread wheat gene pool from its progenitor, Aegilops tauschii (Coss.) Schmalh, 33 primary synthetic hexaploid wheat genotypes (SYN) were crossed to 20 spring bread wheat (BW) cultivars at the International Wheat and Maize Improvement Center. Modified single seed descent was used to develop 97 populations with 50 individuals per population using first b...

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...
