Abstract

Quality, as measured by roast color, flavor and storability, is variable within and among peanut (Arachis hypogaea L.) lots of the same commercial size. Because maturity is significantly related to many quality characteristics, the variability in maturity distributions (percentage of various maturity classes) was examined within sized peanut lots from twenty random samples, an irrigation study, a harvest date study, and a soil temperature study. Pods from each source were separated into hull scrape maturity classes, dried, shelled, and screened to obtain seed size distributions. Using the weight of each maturity class in each commercial size, the percentage weight contribution of each maturity class in each commercial size category was calculated. Seed size distribution for maturity classes from different treatments in each study varied widely. The data indicated that each commercial size category contained peanuts from each maturity class. Treatments within the studies generally produced significant differences among percentages of individual maturity classes in each size. Large standard deviations and coefficients of variation in all studies indicated the wide variability potential in sized lots. The distributions of maturity within commercial sizes were sufficiently different to suggest that flavor, roast color, storability, and other quality estimators would be affected in final roast products from some of the lots.
