ANOVA was performed to evaluate trait differences between
the water treatments (T), among different ILs (G) within each
water treatment, among different ILs within each population,
between ILs from different populations, between ILs from
different selection schemes, and G × T interaction using SAS
PROC GLM [19]. Student t-tests were performed to compare
differences between the selected ILs and the recipient HHZ
for measured traits under each water treatment. Selection
efficiency was assessed for each selection scheme based
on the number of ILs showing significantly improved trait
values.
