Abstract

This study was designed to identify the drought tolerant and susceptible genotypes among 160 wheat genotypes. Analysis of variance under drought condition showed mean square due to genotypes had highly significant differences for all the quantitative traits in both years and pooled data, except flag leaf width, flag leaf area those were significant only and under control condition. Mean square due to genotypes had highly significant differences for all the traits in both the years and pooled data, except plant height in the pooled data that was significant only. On the basis of grain yield per plant under both the conditions twenty one tolerant genotypes namely; DBW 39, FLW 13, FLW 7, HD 2833, HD 3093, HI 1500, HI 617, HW 2004, HW 2005, HW 2066, HW 4002, HW 4008, HW 4029, HW 4215, Lok 1, Lok 65, MACS 2496, RAJ 4037, SOKOLL, SSRT 14, VJ 99 were selected and eleven susceptible genotypes using same criteria namely; DBW 14, DBW 28, DBW 88, HD 2824, HD 2877, NW 1014, PBW 343, PBW 373, RAJ 4083, UP 2828, MACS 6272 were identified. Identified tolerant and susceptible genotypes can be used for development of mapping populations to map the QTLs for drought tolerance in wheat (Triticum aestivum L.).
