2014 journal article

Mapping of powdery mildew resistance gene Pm53 introgressed from Aegilops speltoides into soft red winter wheat

THEORETICAL AND APPLIED GENETICS, 128(2), 303–312.

By: S. Petersen n, J. Lyerly n, M. Worthington n, W. Parks n, C. Cowger n , D. Marshall n, G. Brown-Guedira n , J. Murphy n

MeSH headings : Ascomycota / pathogenicity; Chromosome Mapping; Chromosomes, Plant; DNA, Plant / genetics; Disease Resistance / genetics; Genes, Plant; Genetic Markers; Microsatellite Repeats; Plant Diseases / genetics; Plant Diseases / microbiology; Poaceae / genetics; Polymorphism, Single Nucleotide; Triticum / genetics; Triticum / microbiology
TL;DR: A powdery mildew resistance gene was introgressed from Aegilops speltoides into winter wheat and mapped to chromosome 5BL, and closely linked markers will permit marker-assisted selection for the resistance gene. (via Semantic Scholar)

2013 journal article

A Comparison of Methods for Evaluating the Suppressive Ability of Winter Wheat Cultivars against Italian Ryegrass (Lolium perenne)

WEED SCIENCE, 61(3), 491–499.

By: M. Worthington n, S. Reberg-Horton  n, D. Jordan n & J. Murphy n

author keywords: Indirect selection; organic wheat production; weed interference; wheat breeding
TL;DR: Italian ryegrass seed head density and visual estimates of Italian ryEGrass biomass during grain fill are appropriate indirect methods of selection for weed suppressive ability in breeding programs. (via Semantic Scholar)
