Randall P Niedz

Research Geneticist

U. S. Horticultural Research Laboratory
2001 South Rock Road
Fort Pierce, FL 34945

Telephone: (772) 462-5919

Research Interests:

  • in vitro plant breeding and horticulture
  • micropropagation systems for research and commercial applications
  • experimental design for in vitro experimentation
  • conceptual frameworks for mineral nutrition research, particularly ion confounding.

I use molecular, cellular, and statistical knowledge for the use and development of in vitro methods for plant breeding and horticultural applications, with a specific emphasis on citrus.  In vitro methods are useful for creating plant types that are difficult or impossible to create using conventional methods.  Application examples include transgenics, single-cell derived mutants, haploids and dihaploid homozygotes, parasexual hybrids, plastid and mitochondrial cybrids, triploids and other polyploids, pathogen-free germplasm, mass clonal propagation, and germplasm storage and conservation.



B.S. in Horticulture (Plant Breeding & Genetics) - The Pennsylvania State University

Ph.D. in Plant Breeding & Genetics - Michigan State University

Volunteer Opportunities:

I started a volunteer program that includes projects that are diverse and vary in time commitments, complexity, type, and most importantly, interesting.  Projects include a range of laboratory, computer, and greenhouse activities.  If you have an interest in horticulture, plant breeding, genetics, plant tissue culture, or science in general contact me for additional details.
