Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Agronomy

His primary areas of study are Agronomy, Forage, Agroforestry, Heterosis and Germplasm. His studies deal with areas such as Biomass and Panicum virgatum as well as Agronomy. The concepts of his Agroforestry study are interwoven with issues in Perennial plant, Weed, Species richness, Species diversity and Environmental impact of agriculture.

His work in Perennial plant addresses issues such as Biomass, which are connected to fields such as Quantitative trait locus. His Heterosis study integrates concerns from other disciplines, such as Medicago sativa and Medicago. His study in Germplasm is interdisciplinary in nature, drawing from both Cultivar, Bioenergy, Biotechnology, Hybrid and Selectable marker.

His most cited work include:

  • Biomass yield and quality of 20 switchgrass populations in southern Iowa, USA. (276 citations)
  • Legumes as a model plant family. Genomics for food and feed report of the Cross-Legume Advances Through Genomics Conference. (193 citations)
  • Capturing heterosis in forage crop cultivar development (157 citations)

What are the main themes of his work throughout his whole career to date?

E. Charles Brummer mainly focuses on Agronomy, Medicago sativa, Germplasm, Cultivar and Botany. Many of his studies involve connections with topics such as Biomass and Agronomy. E. Charles Brummer works mostly in the field of Medicago sativa, limiting it down to topics relating to Heterosis and, in certain cases, Medicago falcata and Diallel cross.

His work deals with themes such as Brassica, Microsatellite and Biotechnology, which intersect with Germplasm. His Cultivar study combines topics from a wide range of disciplines, such as Quantitative trait locus, Growing season, Dormancy and Sugar. His study looks at the intersection of Botany and topics like Genetic structure with Gene pool.

He most often published in these fields:

  • Agronomy (58.99%)
  • Medicago sativa (22.30%)
  • Germplasm (20.14%)

What were the highlights of his more recent work (between 2015-2021)?

  • Agronomy (58.99%)
  • Germplasm (20.14%)
  • Heirloom plant (3.60%)

In recent papers he was focusing on the following fields of study:

Agronomy, Germplasm, Heirloom plant, Horticulture and Medicago sativa are his primary areas of study. His research integrates issues of Quantitative trait locus and Agriculture in his study of Agronomy. As a part of the same scientific study, E. Charles Brummer usually deals with the Quantitative trait locus, concentrating on Biomass and frequently concerns with Genetic variation.

The various areas that E. Charles Brummer examines in his Germplasm study include Gene pool, Genetic diversity and Biotechnology. Medicago sativa connects with themes related to Genetic marker in his study. His Subspecies research is multidisciplinary, incorporating elements of Medicago and Botany.

Between 2015 and 2021, his most popular works were:

  • Genome-Wide Association Mapping and Genomic Selection for Alfalfa (Medicago sativa) Forage Quality Traits (55 citations)
  • GBS-Based Genomic Selection for Pea Grain Yield under Severe Terminal Drought. (32 citations)
  • Assessment of Cultivar Distinctness in Alfalfa: A Comparison of Genotyping-by-Sequencing, Simple-Sequence Repeat Marker, and Morphophysiological Observations. (22 citations)

In his most recent research, the most cited papers focused on:

  • Agriculture
  • Ecology
  • Genetics

E. Charles Brummer focuses on Agronomy, Quantitative trait locus, Genetic variation, Cultivar and Germplasm. E. Charles Brummer studies Agronomy, focusing on Plant breeding in particular. His Quantitative trait locus research includes themes of Sugar, Biomass and Lignin.

He has researched Genetic variation in several fields, including Biotechnology, Molecular marker, Allele frequency and Horticulture. His Germplasm study incorporates themes from Ecology, Ecotype, Genetic diversity, Fixation index and Genetic marker. His studies in Genetic marker integrate themes in fields like Medicago sativa, Microsatellite, Neutral Detergent Fiber, Forage and Single-nucleotide polymorphism.
