Research Project: Coordinated Development of Genetic Tools for Pecan

Location: Crop Germplasm Research

Project Number: 3091-21000-042-04-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Sep 1, 2016
End Date: Aug 31, 2021

Objective:
1.Complete genomic sequence of multiple reference types, annotated, accessible. 2.Identification of genetic mechanisms that control horticultural traits. 3.Phenotypic descriptor development, data collection and delivery. 4.Development of linkage populations and dense SNP maps across Carya. 5.Development of marker systems for use in cultivar verification and eventually marker assisted breeding for both rootstock and cultivar development.

Approach:
Development of genetic tools will be focused on existing collections of the National Plant Germplasm System. Existing phenotypic data will be integrated into GRIN-Global, the database of the National Plant Germplasm System. Additional phenotypic descriptors will be developed for targeted parameters, especially focusing on tree architectural traits. Establishment of a database and web portal suitable for storing, analyzing and visualizing the genomic, phenotypic and marker-trait data information generated from this projects. High-density SNP-based linkage maps in pecan will be developed from biparental mapping populations. Generate platforms suitable for high throughput genotyping to characterize pecan cultivars and initiate marker-assisted selection strategies in pecan.
