Research Project: EVALUATION OF ADVANCED USDA CITRUS SCION GERMPLASM

Location: Citrus and Other Subtropical Products Research

2008 Annual Report


1a.Objectives (from AD-416)
Screen novel citrus scion germplasm for unique fruit characteristics.


1b.Approach (from AD-416)
Fruit produced on citrus hybrids will be harvested at three times during the season to identify the maturity window for the particular selection. At the time of harvest data will be collected on fruit appearance (size, shape, presence of disease), rind color, ease of peeling, presence of seeds, soluble solids, total acidity, and taste (unacceptable, potentially acceptable, or acceptable). Scion selections identified worthy of further evaluation will be propagated onto commercial rootstocks for further evaluation.


3.Progress Report

This project is related to Objective 2 of this in-house project: Screen germplasm for important traits and select superior individuals. The objective of this research project is to provide the cooperator with detailed information on characteristics of promising new citrus scion hybrids and increase the number of selections available.

A meeting was held at the United States Horticultural Research Laboratory on July 15, 2008 as per terms of the agreement. Participants included United States Department of Agriculture, Agricultural Research Service and New Varieties Development and Management Corporation representatives. Updates were provided on three advanced scion selections and plans were discussed for naming and release of these selections.

Progress was monitored by regular meetings, phone calls, and email communication.
