Abstract

A method of classification based on color and morphological differences of the mesocarp is described for determining the developmental stages of fresh peanut [Arachis hypogaea (L) ‘Flo-runner’] pods. Developmental stages are designated as Classes 1-7, with each subsequently numbered class representing progressively greater degrees of maturity. For illustration each class is subdivided into one-quarter increments which are represented pictorially by beginning points. Because various combinations of classes and/or subclasses can be used, the system has inherent flexibility to accomodate the degree of refinement dictated by classification needs.Maturity determination by this method requires removal of a portion of the exocarp or epidermis to expose the pod mesocarp. The exocarp can be removed by sand blasting, gentle abrasion, or lightly scraping with a knife. Because removal of the exocarp is non-destructive to the remaining pod structure and enclosed seeds, the method has inherent advantages for use in commercial culture and in biological investigations requiring intact pods and/or seed.
