Yield Stability, Bread Making Quality and Drought Tolerance in Bread Wheat Genotypes

Authors

Abstract

To identify high yielding drought tolerant genotypes with yield stability and good bread making quality, an experiment was conducted using 22 bread wheat genotypes (20 promising lines and 2 checks, Sardari and Azar-2) during two cropping seasons (2007-2009) in Sararood (Kernamshah) and Karaj (moderate cold areas). The genotypes were evaluated in a RCBD with three replications under two separate experiments, full irrigation and rainfed conditions. Based on the results, some genotypes performed higher drought stress tolerance among them genotypes no. 11 (KATILA-13), 19 (CRR/ATTILA),1 (ORF1.158/FDL//BLO/3/SHI4144/CROW/4/C), 14 (KAUZ's'/MACHETE) and 7 (Jcan/Emu"s"//Dov"s"/3/Alvand/4/MV17/AHila) had higher grain yield, yield stability and good baking quality compared to the other genotypes. Genotypes no. 10 (HAMAM-4) and 12 (KATILA-1) had also most of the grain quality characteristics. Based on the results of different characteristics, the genotypes no. 1, 11, and 19 were selected for drought tolerance, yield and yield stability and genotypes no. 10 and 12 for drought tolerance and quality characteristics .
