Abstract

The pot culture experiment was conducted in net house at NIA Tandojam, to observe growth and water use efficiency (WUE) in wheat genotypes grown under water stress. Four wheat genotypes (DH-13, DH-18, DH-20 and LU-26s) were tested along with local drought tolerant check (Chakwal-86). Drought treatment was imposed one month after sowing, by holding the irrigation only @ 30% field capacity. While control pots were irrigated regularly to maintain soil moisture at 100% field capacity.Experiment was terminated at crop maturity and growth and yield observations were recorded. Water use efficiency (WUE) was calculated on the basis of total amount of water use to increase per unit biomass per unit area i.e. (g/m2/mm).The results showed that under water stress conditions, the genotype DH-18 performed well. Studies on water use efficiencies (WUE,) showed that under water stress condition the genotype DH-20 use water more efficiently to produce maximum biomass (1.65 g/m2/mm), followed by DH-18(1.58 g/m2/mm). Better response of DH-18 under drought is encouraging for its recommendation in drought prone areas.
