Abstract

The study was conducted to investigate the “Evaluation of five different wheat genotypes under drought stress conditions at Haripur valley”. The five wheat varieties were sown in pots using Completely Randomized Design (CRD) with three replications. The wheat pots were kept in two different arrangements for drought stress and control condition. The control pots plants was kept in the open climate under ordinary conditions. ANOVA revealed highly significant (p≤0.01) differences for the whole parameters in five different wheat genotypes. The data for eight traits were studied viz., days to 50% heading, days to maturity, number of grains per spike, plant height, 100-grain weight, number of spikelet’s spike-1, number of tillers and spike length. Under drought and controlled conditions maximum values of days to 50% heading, days to maturity, plant height, spike length, number of spikelet’s spike-1, number of grains spike-1, number of tillers and 100-grain weight ranged from 71.33 to 74.66, 122.33 to 128.67, 65.73 to 68.26cm, 9.50 to 10.43, 21.26 to 22.33, 41.33 to 51.67, 4.00 to 4.00 and 2.91 to 3.52 g for drought stress and control, respectively. Similarly minimum values were observed for days to 50% heading (69 to 71.66), days to maturity (120.33 to 123.67), plant height (51.00 to55.73), spike length (8.20 to 9.26), number of spikelet’s spike-1 (19.80 to 21.26), number of grains spike-1 (36.00 to 41.33), number of tillers plant-1 (2.00 to 3.00), 100-grain weight (2.50 to 3.24g) for drought stress and control respectively.
