Abstract: An experiment was conducted during rabi season of 2016–17 and 2017-18 by using nine wheat genotypes viz; AKAW 5023, AKAW 4927, PBN 4905, PBN 4751-02, NIAW 3523, NIAW 2891, AKAW 4210-6 (C), NIAW 34 (C), NIAW 1994 (C) and sowing done at 1-10 December irrigated condition in a randomized block design with three replications to assess the variability of genotypes for morphological traits under heat-stress environment to find out the suitable heat tolerance genotypes for Vidharbha condition. Under late sown conditions morphological traits like, leaf area, LAI, total dry weight plant^-1, plant ht. plant^-1, number of tillers meter^-1 row length, 1000 grain weight (g), grain yield plant^-1, grain yield plot^-1, grain yield/ha (q) were observed. On pooled basis superior performance showed by genotype NIAW 2891 followed by NIAW 3523 over best check AKAW 4210-6 and also higher yield recorded than other genotypes during both the year of sowing and noted as heat tolerance genotypes. These traits can be utilized as selection criteria for improving the grain yield in the warmer wheat growing areas for terminal heat-stress.
