Table 1. Overall means, minima, maxima, and
coefficients of variation (CV) of the phenotypic values with respect to
the selection traits. The upper panel provides results from the 90 dura
lines (Experiment 1), along with the means and standard deviations (s.d.)
per main origin. The lower panel provides the results of the 20 tenera ×
pisifera families (Experiment 2), along with the means and ranges per
origin. The lowest line presents data from Family 13 of the Nigeria
origin
