Six populations viz., P1, P2, F1, F2, B1 and B2 of four crosses involving eight parents were evaluated following compact family block design during kharif season in 2008 to 2011 to study the mode of inheritance by using simple (A, B, C and D) and joint scaling tests. The nature and magnitude of gene effects for yield and its components in Barley was also studied using six parameters model of generation mean analysis. The presence of epistasis was detected in 64 cases by simple as well as joint sealing test and inadequacy of additive-dominance model was established. Additive (d), dominance (h) gene effects along with one or more type of non-allelic interaction (i, j, l) contributed significantly towards the inheritance of all the quantitative characters in majority of the crosses. Duplicate type of epistasis was also prevalent in most of the cases with few exceptions. Thus, biparental mating may be suggested for improvement of Barley populations.
