  1. Seed composition traits were determined based on near-infrared (NIR) spectroscopy calibration curve (Dykes et al. [45]) from fresh seed obtained from Isabela, Puerto Rico in 2013. Means followed by a common letter are not significantly different according to Fisher’s least significant different test
  2. 1Values are based on percent
  3. 2Total phenols based on milligram of gallic acid equivalent (GAE)/gram
  4. 3Condensed tannins based on milligram of catechin equivalents (CE)/gram
  5. 43-Deoxyanthocyanidins content based on absorbance (abs)/milliliter/gram
  6. n.s., ** and *** refers to no significant, and significant effects at p ≤ 0.01 and .005, respectively
  7. C.V. refer to coefficient of variation
