Goals / Objectives
1. Use traditional and molecular breeding approaches to develop enhanced germplasm with the potential to minimize economically significant production constraints of potato in the East. 2. Utilize improved germplasm to develop high quality, pest-resistant varieties for fresh market, specialty, and/or processing use. 3. Identifiy and quantify significant climatic and cultural effects on the performance of potato selections.
Project Methods
Advance yellow-fleshed potato selections as well as some of the more intense yellow-fleshed hybrids available, will be grown in replicated field studies in FL, NC, and ME. Tuber carotenoid content will be analyzed by HPLC. The stability of tuber carotenoid composition across different growing environments will be ascertained.

Progress 10/01/04 to 09/30/05

Outputs
Over 350 potato varieties and breeding lines were evaluated in replicated trials by grouping the potatoes by type, color, or use. Six lines of red-skinned potatoes were in a state wide trial in three locations. One of the trials was part of the NE- Regioal Project Variety Trial conducted in seven states. Results are found in the Florida Chip and Fresh Market Potato Variety Trial Report, 2005, University of Florida, IFAS. Twelve advanced yellow-fleshed potato selections as well as more intense yellow-fleshed hybrids were grown in replicated a field study completing a two year study in FL and ME. Tuber carotenoid content will be analyzed by HPLC. The stability of tuber carotenoid composition across different growing environments will be ascertained.

Impacts
The Florida potato industry needs better quality fresh and processing cultivars. This program is evaluating breeders lines to find superior quality, yield, and marketability to provide growers and consumers the best possible product.This is a continuing process to keep the Florida industry conpetative and profitable.

Progress 10/01/03 to 09/30/04

Outputs
Over 234 potato varieties and breeding lines were evaluated in replicated trial by grouping the potatoes by type, color, or use. Eight lines of red-skinned potatoes were in a state wide trial in seven locations. One of the trial was part of the NE- Regional Project potato variety trial conducted in several states. Results are found in the Florida Chip and Fresh Potato Variety Trial Report, 2004, University of Florida, IFAS.
