On-Line Database for Peach Germplasm Evaluation

A MySQL database was created to enter data from our long-term peach germplasm evaluation program at Clemson University.  This database is updated on-line and is linked to our peach germplasm evaluation website (http://www.clemson.edu/hort/Peach/index.php?p=73).  Peach evaluation data that is collected in the field and the lab throughout the summer is uploaded to the database within 24 hours and is readily accessible to our on-line clientele. Our website is regularly utilized by consultants, growers, researchers, extension specialists and agents throughout the U.S. and in several foreign countries.  Currently, the database includes up to 10 years of data (2000-2009) depending on the cultivar or numbered selection. The database includes the following information for each individual record: year, location, cultivar or numbered selection, ripening season, flesh color, chill hour requirement (if available), bloom date, ripe date, set (% of full crop), size (average diameter), shape, pubescence, red skin coloration, attractiveness, flesh firmness (average puncture pressure), freeness of stone, overall status, brix (average soluble solids concentration), evaluation notes, and full description if available (from formal release or issued patent).  Linked to each individual record is a digital image of the fruit at the time of harvest.  All fruit photographs are taken on a standard 1 inch x 1 inch grid background that includes six fruit views per sample (stem end, tip end, suture side, non-suture side, longitudinal section and cross section).  A powerful search feature allows searching across all records in the database. In addition, a side-by-side comparison feature was created to make possible direct comparisons on the screen.  This database allows growers to do their own homework and fine-tune their decision making about choosing new cultivars for future plantings.  Specialists and county agents and others use the site to familiarize themselves with cultivars used in the trade or make recommendations themselves.
