    Fatty Acid composition of the peanut collection analyzed using a gas chromatograph (GC)

    The U.S. germplasm collection for cultivated peanut, Arachis hypogaea L. contains a great amount of genetic diversity. The development of a core collection for peanut provides a subset of accessions that are representative of the entire collection and that, could be extensively examined. In order to select a core collection for peanut, the peanut germplasm collection was stratified by country of origin and by the amount of available morphological data. When information was available for at least four of the same morphological variables for at least 16 accessions from the same country of origin, then the data for these accessions were analyzed using multivariate statistical analysis. Results allowed the accessions to be clustered into groups which, theoretically, are genetically similar. Random sampling was then used to select about 10% from each group. Accessions with inadequate data for multivariate analysis were selected using a 10% random sample from each country of origin. Accessions from countries having few (<=5) entries in the collection were pooled and a 10% random sample was selected. The resulting 831 accessions form a core collection for peanut. Examination of data for six phenotypic traits indicated that the genetic variation expressed for each trait in the entire collection has been preserved in the selected core collection.

    The complete list of accessions used by Holbrook et al to select the peanut core may be viewed or downloaded as an Excel file: Selection of a Peanut Core Collection.

    Additional information about the traits evaluated, as well as material and methods, is available as an Acrobat file (pdf)

    A mini core of the U.S. Peanut germplasm collection. A 10% sample resulting in a core of the core collection (mini core) based on eight above-ground and eight below-ground morphological characteristics. The above-ground descriptors were growth habit, plant size, prominence of main stem at mid-season, prominence of main stem at harvest, presence of flowers on the main axis, leaf color, stem pigmentation, and maturity. The below-ground descriptors were measrued post harvest and included pod shape, pod constriction, pod reticulation, seed per pod, 100-pod weight, U.S. pod market type, seed coat color, and 100-seed weight.
