The present investigation was carried out with the objective to estimate genetic variability involving 65 genotypes (fifteen parents and fifty F1s crosses) grown in a randomized block design with three replications at crop research farm Nawabganj. The analysis of variance revealed the significant differences among the treatments for five characters out of eight characters indicating considerable variability among the genotypes for number of grain/spike, grain yield/plant (gm), test weight/1000 grain weight (gm), harvest index (%) and protein content. Variability also reflected based on mean, range, phenotypic coefficient of variation and genotypic coefficient of variation therefore selection of the parents under study based on morphological differences for different characters was validated through ANOVA and other parameters. The range varied from 54.20 to 71.80 for number of grains in parents and 56.60 to 66.06for number of grains/spike in F1 generation. Maximum phenotypic coefficient of variation (PCV) of traits grain yield/plant (gm) (36.76) for parents+F1s were generally higher than genotypic coefficients of variance (GCV) of traits grain yield/plant (gm) (36.72) indicating the presence of enough genetic variability in the material under study.
