Location: Plant Genetic Resources Conservation Unit

2011 Annual Report


1a.Objectives (from AD-416)
The objective of this research is: 1. To identify resistant germplasm for rust and leafspot. 2. To process imported germplasm through plant quarantine. 3. Transfer disease-free germplasm to the University of Florida cooperator.


1b.Approach (from AD-416)
Our approach is to identify peanut material from literature and other germplasm collections resistant to leafspot and rust. Also, we will process material imported to the U.S. for the project through plant quarantine and ship the material to our University of Florida Cooperator.


3.Progress Report

This research relates to inhouse Objective 3: Strategically characterize (“genotype”) and evaluate (“phenotype”) priority vegetable, sorghum, peanut, subtropical/tropical legume, and warm-season grass genetic resources for molecular markers, morphological descriptors, and key agronomic or horticultural traits such as biochemical content and product quality. The objectives of this research are to identify resistant peanut germplasm for rust and leaf spot and process imported germplasm through plant quarantine. A total of 47 lines from Bolivia were shipped to Griffin, GA to be processed through quarantine. Once the material has been found to be disease free and produce seeds, this germplasm will be sent back to the University of Florida cooperator for disease resistant evaluations. These lines have been tested for peanut stripe and peanut mottle virus and samples found to be positive were destroyed.

Progress was monitored via email correspondence with the investigator.
