Research Project:
Development of Pest, Disease Resistance, and Stress Tolerance in Apple Rootstocks
Location: Plant Genetic Resources
Project Number: 1910-21000-023-00
Project Type:
Appropriated
Start Date: Mar 28, 2008
End Date: Mar 27, 2013
Objective:
1. Develop and release improved apple rootstocks.
2. Develop and apply genomic and bioinformatic tools to marker-assisted selection of apple rootstocks.
Approach:
Develop and release improved apple rootstocks. Perform all breeding and evaluation stages involved in the 15-25 year process of developing new rootstocks with the assistance of recently developed breeding tools, such as marker-assisted selection. Develop improved propagation methods that speed the distribution of selected material to customers through established networks of cooperating nurseries. Exogenous treatments of layering propagation stool beds will increase adventitious root formation and quality of nursery liners. Incorporate innovative concepts of orchard establishment and management including mechanization. Existing experimental rootstocks in the breeding pipeline possess adaptations for novel orchard concepts and mechanization. Develop and apply genomic and bioinformatic tools to marker-assisted selection of apple rootstocks. Develop algorithms to assist with identifying specific markers for priority horticultural traits from the large body of expressed sequence tags (EST) and genomic sequence data now available.
