Abstract: Twenty genotype of wheat were evaluated in randomized block design (RDB) with three replication for yield and yield contributing traits during 2016-2017, find out genetic variability, Heritability and genetic advance percent of mean. Analysis of variance for the design of experiments has been present in for all the eleven characters. The square due to treatment were highly significant for all the eleven characters in both (E₁ & E₂) conditions except for number of spikelets per spike and number of grains per spike in E₁ condition. Phenotype coefficient of variation revealed that grain yield per plant exhibited highest value of PCV followed by biological yield per plant, number of number of effective tillers per plant, number of grains per spike, plant height and number of spikelets per spike. The maximum value of genotypic coefficient of variation was found for grain yield per plant followed by number of effective tillers per plant, biological yield per plant and plant height. High heritability estimates were associated with high estimates of genetic advance for plant height, number of effective tillers per plant, biological yield per plant and grain yield per plant which in fact demonstrated the presence of additive gene effects indicating effectiveness of selection for improvement of these traits.
