Pecan Cultivars


   Each fall we collect nut samples of all the pecan cultivars we have under test at the pecan experiment field. The photos below represent the samples we collected from the 2013 pecan crop. The cultivar portraits are arranged in alphabetical order. Nut weight and percent kernel data for 2013 is given on the photo.  When looking at the photos, be aware that each photo was taken using the same scale so that the nut size and shape of one cultivar can be directly compared to all other cultivars in the portrait gallery.  Below each portrait is additional information including cultivar origin, nut stats, and additional tree attributes.
    After the harvest of the 2014 crop, I'll be adding additional cultivar data, additional cultivars and new photos.
