Table 1. Grand means, minima,
maxima, and coefficients of variation (CV) of the phenotypic values with
respect to each selection trait. The upper panel provides the results of
the 90 dura lines (Experiment 1), along with the data patterns and
their standard deviations (s.d.) for the (four) main origins
(Dami; Chemara; Harrisons & Crosfield (H&C); and MARDI).
The lower panel provides the result of the 20 tenera x pisifera
families (Experiment 2), along
with the data patterens (results) and ranges within the (sub) groups of
the (five) origins (AVROS; Dami composite, Ekona; Ghana;
and Nigeria). The lowest line presents the data from Family 13 of the Nigeria
origin.
