| The purpose of this study was to determine bread wheat genotypes with high yield potential and stability under controlled field conditions which resembled drought types exist in different plant growth stages in the Central Anatolia Region.This study was conducted using split-plot arrangement in randomized complete block design with four replications, the main plots were five drought treatments (D1: the general drought that represents the long term drought in region, D2:drought from the initiation of stem elongation to the initiation of heading stage, D3:drought from the initiation of heading to the end of flowering stage, D4:drought during grain filling period, D5: full irrigation) and ten bread wheat genotypes (Karahan 99, Bayraktar 2000, Gerek 79, Dagdaş 94, Bezostaja 1, Goksu 99, Konya 2002, BDME 09/1 K, BDME 09/2 K and 08-09 KEBVD 24) were the subplots under rain shelter in 2009-2010 and 2010-2011 plant growing seasons in Konya. The yield responses of bread wheat genotypes to drought stress were evaluated by drought susceptibility index (DSİ) and yield stability parameters.The results showed that grain yield values varied from 5771 (D3) to 8111 kgha-1(D5) by drought treatments, and from 5686 (Goksu 99) to 7552 kgha-1 (Konya 2002) among genotypes. The grain yields of genotypes under D1, D2, D3 and D4 treatments compared to decreased 15.3, 16.6, 28.8 and 23.7 % respectively. DSI values ranged between 0.674 (Dagdas 94) – 1.919 (Goksu 99). BDME 09/1K and BDME 09/2K were varieties with wide adaptation and stability while Goksu 99 had the lowest grain yield levels in all drought stress conditions |
