NESTED ASSOCIATION MAPPING TO IDENTIFY SEED COMPOSITION QTL IN DIVERSE SOYBEAN LINES
Soybeans are economically the most important legume grown worldwide. It provides quality protein and oil to food and feed markets in addition to being used for industrial products. The value of soybean could be enhanced by increasing protein, oil, and sucrose contents, while lowering …

Using a barley Nested Association Mapping (NAM) Population to mine wild barley germplasm for crop improvement
… study, we have used the multi-parental barley Nested Association Mapping (NAM) population HEB-25,, comprising 1,420 lines, sub-divided into 25 families, each of which was generated by crossing the spring barley cultivar Barke with one of 25 different wild barley accessions. This thesis …

Genome-wide association study of Barley Yellow Dwarf Virus resistance in a Nested Association Mapping population of winter wheat using Skim Exome Capture and Practical Haplotype Graph imputation
… approach. In this study, a genome-wide association study (GWAS) was conducted to identify loci associated with BYDV resistance in a Nested Association Mapping (NAM) population of winter wheat derived from ‘Overland’. Phenotypic evaluations were conducted under natural BYDV infection, …

The Genetic Architecture Of Quantitative Disease Resistance In Maize
… L. anamorph Exserohilum turcicum). The maize nested association mapping (NAM) population, a reference design population consisting of 4,630 recombinant inbred lines, was evaluated over three environments for quantitative resistance to NLB, giving highly heritable resistance phenotypes. Over …

Genetic improvement of aphid resistance, protein, and elemental composition in soybean
… higher yielding aphid resistant cultivars. Fine Mapping of the Soybean Seed Protein QTL cqSeed protein-003 Soybean is a widely grown, important source of protein and oil for both animal and human consumption. In this study, the previously identified protein QTL cqSeed protein-003 on chromosome 20 …

Genetics of Maize Inflorescence Architecture
… or showed high correlations. The maize nested association mapping (NAM) panel, a tremendous genetic resource developed for genome-wide high-resolution mapping, was used to more precisely understand the genetic architecture of tassel traits. This resource will help considerably to …

Assessing wild barley germplasm in multiparent and advanced backcross populations for mapping, gene discovery, and improvement of malting barley
… backgrounds using advanced backcross (AB) and nested association mapping (NAM) techniques. To do this, we created a wild barley AB-NAM population by backcrossing 25 wild barley accessions to the 6-rowed malting barley cultivar Rasmusson. The 25 wild barley parents were selected to capture …

High-Throughput Phenotyping and Genomic Prediction in Multi-Environment Plant Breeding Field Trials
… a diverse hexaploid wheat (Triticum aestivum L.) nested-association mapping population consisting of 1160 recombinant inbred lines was evaluated in yield trials conducted at three locations during the 2020 and 2021 growing seasons. UAV-based multispectral imaging was conducted at 10-15 timepoints …

High-throughput phenotyping and genetic mapping of photosynthetic traits and ozone responses in maize and soybean
… was demonstrated by performing a genome-wide association study on the entirety of the Soybean Nested Association Mapping panel over two growing seasons. Significant marker trait associations were identified for both rate limiting steps of photosynthesis (normalized to 25°C), specific leaf …
