Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Botany
  • Genetics

His main research concerns Genetics, Cultivar, Germplasm, Genetic diversity and Allele. Cultivar is the topic of his studies on Horticulture, Botany and Agronomy. His Botany study combines topics from a wide range of disciplines, such as Crop and Animal science.

His Germplasm research incorporates themes from Genetic marker, Genotype, Haplotype and Fusarium solani. His biological study spans a wide range of topics, including Agroforestry and Soil retrogression and degradation. Randall L. Nelson usually deals with Allele and limits it to topics linked to Gene pool and Gene–environment interaction, Backcrossing, Epistasis, Seed protein and Microsatellite.

His most cited work include:

  • Increasing CO2 threatens human nutrition (572 citations)
  • Impacts of genetic bottlenecks on soybean genome diversity. (490 citations)
  • Development and evaluation of SoySNP50K, a high-density genotyping array for soybean. (335 citations)

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

Germplasm, Cultivar, Agronomy, Botany and Horticulture are his primary areas of study. He combines subjects such as Genetics, Biotechnology, Genetic diversity and Genotype with his study of Germplasm. His study looks at the relationship between Genetic diversity and topics such as Genetic marker, which overlap with RAPD.

Randall L. Nelson focuses mostly in the field of Cultivar, narrowing it down to topics relating to Phytophthora sojae and, in certain cases, Agricultural experiment station. His work on Crop, Growing season, Grain filling and Yield as part of general Agronomy research is often related to Maturity, thus linking different fields of science. The various areas that Randall L. Nelson examines in his Botany study include Gene pool, Glycine and Animal science.

He most often published in these fields:

  • Germplasm (37.77%)
  • Cultivar (37.23%)
  • Agronomy (34.57%)

What were the highlights of his more recent work (between 2014-2021)?

  • Quantitative trait locus (12.77%)
  • Genetics (22.34%)
  • Agronomy (34.57%)

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

Randall L. Nelson mainly investigates Quantitative trait locus, Genetics, Agronomy, Germplasm and Single-nucleotide polymorphism. His research integrates issues of Genetic marker, Agriculture, Climate change and Inbred strain in his study of Agronomy. His Germplasm research includes themes of Genetic diversity, Linkage disequilibrium, Haplotype, Domestication and Glycine soja.

His study looks at the relationship between Gene pool and fields such as Plant biochemistry, as well as how they intersect with chemical problems. His study in Association mapping is interdisciplinary in nature, drawing from both Cultivar and Genomics. His Cultivar study deals with the bigger picture of Horticulture.

Between 2014 and 2021, his most popular works were:

  • Genetic Diversity in Soybean (132 citations)
  • Genome-wide association study for flowering time, maturity dates and plant height in early maturing soybean (Glycine max) germplasm (128 citations)
  • Fingerprinting Soybean Germplasm and Its Utility in Genomic Research (119 citations)

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

  • Gene
  • Botany
  • Genetics

His main research concerns Genetics, Quantitative trait locus, Single-nucleotide polymorphism, Genome-wide association study and Cultivar. His Genetics study frequently links to related topics such as Germplasm. His work carried out in the field of Germplasm brings together such families of science as Genetic diversity, Linkage disequilibrium, Haplotype, Domestication and Locus.

The concepts of his Single-nucleotide polymorphism study are interwoven with issues in Agronomy, Nested association mapping, Gene mapping, Allele and Genetic architecture. Randall L. Nelson interconnects Essential nutrient and Nutrient content in the investigation of issues within Agronomy. Randall L. Nelson works mostly in the field of Cultivar, limiting it down to topics relating to Association mapping and, in certain cases, Biotechnology and Gene–environment interaction, as a part of the same area of interest.
