Project Number: 8060-21000-028-05-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Sep 1, 2015
End Date: Aug 31, 2020
The objective of this cooperative project is to characterize genetic and genomic diversity of the USDA-ARS Geneva apple and grape germplasm for improving disease/pest resistance, adaptation to abiotic environment, fruit quality, and/or plant architecture traits in these two crops.
We will initially focus on rootstock germplasm. Apple and grape rootstock germplasm will be selected from the clonal germplasm repository and evaluated for rooting ability, root architecture, and/or adaptation to adverse soil conditions. Then the rootstock germplasm with contrasting phenotypes and their cross progeny will be characterized through deep genomic sequencing and RNAseq analysis.
