Resorcinolic lipid contents and homologue compositions in extracts isolated from soft winter, soft spring and hard (durum) wheat grains were evaluated by both instrumental and chromatography means. Resorcinol concentrations determined in wheat were diverse and varied in samples harvested within two consecutive vegetative years, whereas their homologue profiles were found to be rather invariable...

Rusts are important pathogens of angiosperms and gymnosperms including cereal crops and forest trees. With respect to cereals, rust fungi are among the most important pathogens. Cereal rusts are heteroecious and macrocyclic requiring two taxonomically unrelated hosts to complete a five spore stage life cycle. Cereal rust fungi are highly variable for virulence and molecular polymorphism. Leaf r...

Gene flow between jointed goatgrass and winter wheat is a concern because transfer of herbicide-resistance genes from imidazolinone-resistant (IR) winter wheat cultivars to jointed goatgrass could restrict weed-management options for this serious weed of winter wheat cropping systems. The objectives of this study were (1) to investigate the frequency of interspecific hybridization between IR wh...

Cereal Chem. 80(3):316–322 Reflectance spectra (400 to 1700 nm) of single wheat kernels collected using the Single Kernel Characterization System (SKCS) 4170 were analyzed for wheat grain hardness using partial least squares (PLS) regression. The wavelengths (650 to 700, 1100, 1200, 1380, 1450, and 1670 nm) that contributed most to the ability of the model to predict hardness were related to pr...

Fusarium head blight (scab) is a problem for wheat production in high rainfall areas. This report of research examining the response varieties on disease susceptibility and yield quality. Hard red had more than soft 2021. Wheat was correlated with severity.

Historically cultivars developed jointly by the University of Nebraska-Lincoln and USDA-ARS wheat (Triticum aestivum L.) improvement project tend to be late better adapted northern Great Plains. LCS ‘Valiant’ (Reg. no. CV-1196, PI 693223; tested as NE10478-1) was released based on merits its earliness, agronomic performance, relevant disease resistances, end-use quality characteristics adaptati...
