Development of a PCR assay and marker-assisted transfer of leaf rust and stripe rust resistance genes LR57 and YR40 into hard red winter wheats
The wheat (Triticum aestivum L.)-Aegilops geniculata introgression T5DL·5DS-5MgS(0.95), with stripe rust resistance gene Yr40 and leaf rust resistance gene Lr57, is an effective source of resistance against most isolates of the rust pathogen in Kansas and India. Rust resistance genes Lr57 and Yr40 were transferred to the hard red winter wheat (HRWW) cultivars Jagger and Overley by standard ...

Effects of the chromosome region including the Gpc-B1 locus on wheat grain and protein yield
The recent cloning of the Gpc-B1 gene from Triticum turgidum ssp. dicoccoides (Körn. ex Asch. and Graebn.) Thell. (DIC hereafter) chromosome 6BS revealed that modern wheat varieties have a nonfunctional allele. The DIC allele accelerates senescence and increases grain protein concentration (GPC) relative to the nonfunctional allele, but its effect on yield is not known. Here we describe the ...

Quantifying straw removal through baling and measuring the long-term impact on soil quality and wheat production
Crop residues are considered the feedstock of choice for the production of ethanol, but removing crop residues may negatively impact soil productivity. The objectives were to quantify the proportion of total aboveground crop residues removed through baling and to evaluate the effects of 50 yr of straw removal with baling on soil quality and wheat (Triticum aestivum L.) production. The first study ...

Measuring grain protein concentration with in-line near infrared reflectance spectroscopy
The advent of near infrared (NIR) on-combine sensors gives growers the opportunity to measure the grain protein concentration of wheat (Triticum aestivum L.) during harvest. A study consisting of three sequential experiments (laboratory bench, combine test stand, and field) was conducted to evaluate the performance of an in-line, NIR reflectance spectrometer, referred to as the ProSpectra Grain ...

Wheat grain quality response to tillage and rotation with field Pea
Preceding spring wheat (Triticum aestivum L.) with field pea (Pisum sativum L.) can enhance wheat grain yield in a wheat-pea (WP) rotation compared with continuous wheat (WW). The pea-rotation benefits to wheat grain quality are uncertain. A 6-yr study was conducted to determine (i) if grain protein content, kernel weight, and test weight were enhanced for wheat in a WP rotation compared with WW, ...
