Abstract:
The primary aim of plant breeding is to improve sta
bility in yield and to obtain
varieties with good quality. For this reason, a stu
dy of wheat varieties was conducted in
2010, 2011, and 2012 at the Agricultural Applicatio
n and Research Center fields of the
Uludag University, Agricultural Faculty, in Bursa/T
urkey. In the study, 22 advanced lines
of bread wheat and Gonen, Pehlivan, and Flamura cul
tivars as controls were examined in
a 3-year experiment. In each year, the experiment w
as conducted in randomized block
design with three replications. The effects of cult
ivars, environment, and
genotype×environment interactions were evaluated. R
esults of the study permitted us to
distinguish three lines, namely, (Gx22-1)-4, (Gx22-
1)-6, and (GxK) which were
characterized by higher adaptation capabilities and
stability than those of the other
genotypes.
