Two experiments were carried out during winter season of 2010-2011 at two different
locations Halabja and Qlyasan research station in order to study the response of some triticale
(Roaeda, Eronga-95 and Clossbied) and barley (IPA 99, Bip 999 and NS 313) genotypes under
four different seeding rates (80, 120, 160, 200 kg/ha), and their interactions on some growth
and agronomic characters. Using Split Plot Design in which main plots in RCBD with three
replications. The results showed significant differences among genotypes for all agronomic
characters at both locations and their average with the exception of flag leaf area and flag leaf
dry weight during Qlyasan location. The statistical analysis revealed non significant effects of
seeding rates on growth and agronomic characters at both locations and their average with the
exception of number of days from seeding to physiological maturity, which was highly
significant at both locations with their average. There were no significant differences due to
the effect of interaction between genotypes and seed rates on growth and agronomic
characters at both locations and their average.

Keywords: Genotypes; barley; triticale; hybrid; breeding; seeding rates; agronomic.
