Table 2. Overall means, minima, maxima, and coefficients of variation of GCA-values per trait of all 225 dura and 50 pisifera parents of Experiment 3, along with the mean values per origin of the parents of the dura lines from Experiment 1 and all 50 pisifera palms. Per pisifera origin, the trait values of the palm with the highest value for oil yield (or Elite palm) are presented
