Abstract
An experiment was conducted during two rabi seasons of 2008-09 and 2009-10 on wheat to find suitable physiological traits in wheat genotypes for restricted irrigation application in concrete drought plots. The experiment was designed as split plot consisting of three irrigation schedules viz., normal irrigated (control), two irrigations at 25 and 105 DAS (moderate stress) and single irrigation at 25 DAS (rainfed) in the main plots and four genotypes namely WH 1025, WH 1080, WH 1081 and C 306 in the sub-plots with three replications. The moisture stress created by restricting the irrigation decreased the leaf water potential (LWP), canopy temperature depression (CTD), transpiration rate, stomatal conductance and photosynthesis. Moisture stress decreased the yield and yield attributes with maximum reduction in number of tillers per plant followed plant height and ear length. Among the genotypes, WH 1080 produced significantly higher yield due to higher test weight, plant water status and higher rate of photosynthesis of flag leaf during anthesis compared to other genotypes under rainfed condition.
