Identification of Wheat Genotypes Under Drought Stress Conditions at Early Germination Stage

Muhammad Iqbal, Munir Ahmad, Asim Mehmood

Abstract


Wheat (Triticum aestivum) is a staple crop of most of the irrigated as well as rainfed areas of the world including Pakistan. Thirty wheat genotypes were used to study the effect of low moisture stress by using Polyethylene Glycol (PEG-6000) under concentration (0%, 15% and 25%) of PEG-6000 at the germination stage. Data was recorded for germination percentage, shoot length, root length, coleoptile length, shoot dry weight and root dry weight. The results of the analysis were significant and positively Co-related among all parameters. About fourteen genotypes shows 100 % germination in both control as well as under 15% PEG-6000 conditions. Chakwal- 81, Punjab- 2011, AAS- 2011, Pirsabak- 2005, Pakistan- 2013, Chakwal- 50, Pisabak - 91 and Lasani- 2008 performance was better under control as well as 15 % PEG-6000 among all thirty genotypes. While AAUR-10 and Bhakkar-2002 showed no growth under all three concentrations because of fungal growth.
