Therefore, this field experiment was conducted to assess the genetic variability in bread wheat genotypes. The field evaluation of 32 genotypes and 4 released varieties was conducted in 6 x 6 Triple Lattice Design at Mehoni Agricultural Research Station in 2017 cropping season. Results of analysis of variance revealed the presence of significant differences among genotypes for 12 quantitative traits. The variation observed among genotypes for grain yield ranged from 2.80 to 5.33 t ha-1. The four genotypes (QAFZAH-2/FERRIUG-2, KAUZ'S'/FLORKWA1//GOUMRIA-3, ETBW5957and SERI 82/SHUHA'S'//PASTOR-2 had yield advantage of 7.58 to 12.21% over the high yielding check variety, GAMBO (4.75 t ha-1). Phenotypic (PCV) and genotypic (GCV) coefficient of variations ranged from 5.67 (plant height) to 14.74 (fertile tiller per plot) and 7.06 (days to maturity) to 19.08% (fertile tiller per plot), respectively. Heritability (H2) in broad sense and genetic advance as percent of mean (GAM) ranged between 41.46 (biomass yield) and 89.08 (days to heading) and 8.56 (plant height) and 24.09% (harvest index), respectively. High H2 estimates coupled with moderate or high GAM for plant height, days to heading, days to maturity, spike length, grain yield, spikelets per spike and harvest index suggested the higher chance of improving these traits through selection of genotypes for high mean performance.
