ABSTRACT

Field experiment was laid out in randomized block design, replicated thrice under rainout shelter during kharif, 2015 and kharif 2016 at Indian Institute of Millet Research (IIMR), Hyderabad. The moisture stress was imposed from panicle initiation to grain filling stage.Growth and physiological traits viz., leaf area, total dry matter ,harvest index and grain yield significantly reduced under imposed moisture stress conditions compared to irrigated control. Among the thirty genotypes,imposed for moisture stress GE-1034,GE-639, GE-1034 and GE-224 recorded significantly higher physiological efficiency in terms of leaf area, total plant drymatter along with higher HI and yield. It denotes their efficiency in performing under drought condition.
