Drought is the main abiotic stress factor and low rainfall during grain filling period affect bread wheat yield and yield

component. This experiment was carried out in the experimental field of Trakya ARI, Edirne (Turkey), in 2008-2009

and 2009-2010 years. Totally, 15 genotypes were planted in RCBD in a split-plot with three replications. The main

plots were assigned to five moisture regimes, which included 3 drought stress environments, one non-stress and one

non-treatment environment. Droughts were created under mobile rain shelter at various plant growth stages from

shooting up to maturating stage. Stability parameters were determined for grain yield, biological yield, harvest index,

spike number per square meter, kernel and spikelet number per spike were investigated. A joint regression analysis

was applied to grain yield and other yield component to estimate the stability parameters; mean yield (x),


determinations coefficient (R2), regression coefficient (b), deviation from regression coefficient (S2d), and intercept

value (a). The highest yield (658.3 kg/da) was determined in Bereket and biological yield (2539.4 kg/da) in Kate A-1

cultivar. The highest grain and biological yield was obtained under non-stress condition. For grain yield, it was

determined that Kate A-1 and BBVD7 were adapted to well environmental conditions, Bereket was well adapted to

all environment condition. For biological yield Pehlivan, BBVD7 and Bereket were well adapted to all environmental

conditions. Wide range of stability statistics was determined among cultivars for all the parameters. Gelibolu and

Bereket were the stable cultivars on the basis of overall mean yield and stability parameters.
