Interpretive Summary: The Uniform Peanut Performance Tests (UPPT) were established through an informal arrangement among cooperating scientists from US peanut producing states. The purpose of these tests is to evaluate the commercial potential of advanced peanut breeding lines not formally released. The UPPT serves as a valuable testing arrangement for US peanut breeding programs to measure the adaptability of potential new cultivars over a wide range of diverse environments. Annually, a uniform set of advanced breeding lines are chosen and tested against the same set of check cultivars. The USDA, ARS, National Peanut Research Laboratory (NPRL) in Dawson, Georgia and the USDA, ARS, Market Quality and Handling Research Unit (MQHRU) in Raleigh, North Carolina conduct extensive programs to assist in cultivar quality assessment. The NPRL publication presents data concerning physical and shelling characteristics of breeding lines grown at planting locations across the US peanut producing areas. Extensive physical property data is presented both by location and by breeding lines. Data demonstrate the environmental effects on variability of physical and shelling properties of peanuts produced from different areas of the United States.

Technical Abstract: The Uniform Peanut Performance Tests (UPPT) were established in 1973 through an informal arrangement among cooperating scientists from seven major peanut producing states involved in peanut variety development. The purpose of these tests is to evaluate the commercial potential of advanced peanut breeding lines not formally released. To assist the UPPT, the USDA, ARS, National Peanut Research Laboratory (NPRL) and the USDA, ARS, Market Quality and Handling Research Unit (MQHRU) have conduct programs to assist in cultivar quality assessment for participating scientists and the US peanut industry. Shelling and physical properties for the 2002 UPPT were determined to provide information relevant to industry shelling and post harvest processing. Thirteen varieties were evaluated including check varieties. Data from the 2002 evaluations are presented in two extensive volumes with analyses both by location and variety. Physical properties evaluated included bulk density, commercial grade outturn, pod and seed size distributions, seed count per pound, shelling rates, and moisture content. Comparisons are published in spreadsheet form along with appropriate summary graphs. The two volumes provide good estimates of commercial shelling properties of new varieties being developed demonstrating the effects of yearly environmental and production location variability.
