yield related traits under drought and non-stress
conditions among ILs within the same or different BC populations
indicates that considerable genetic gain can be achieved
through selection for secondary target traits among the ILs.
However, initial selection for different traits resulted in ILs that
varied considerably for the measured traits, suggesting that
selection efficiency for secondary target traits would be very
different for ILs selected for different primary traits. Selection
for secondary target traits can be done more effectively by
screening resistances/tolerances to different biotic and abiotic
stresses and quality traits through replicated progeny testing of
the ILs. In this regard, the developed ILs provide useful
materials for genetic andmolecular dissection of complex traits
using functional genomic tools [23] and for developing high
yielding GSR cultivars with multiple green traits using new and
innovative molecular breeding strategies [
