The objective this study was to effect of gene effects for some agronomical traits (plant height, number of effective tillers per plant, number of spikelet per spike, number of seeds per plant, seed yield and biological yield) of Cross I CG1608 (HI 1544 x GW 2013-513) and Cross II CG 1639 (RAJ 4270 x GW 366) The experimental material comprising of six generations ( P1, P2, F1, F2, BC1 and BC2) of wheat crosses was planted during rabi 2018-19 in randomized block design of two replication under irrigated condition at All India Co-ordinated Wheat and Barley Improvement Project at B.T.C College of Agriculture and Research Station, Bilaspur, Chhattisgarh, India. The scaling test A, B, C and D scale in both the crosses which indicated the result that there is presence of one, two or all the three type non-allelic interaction or epistasis. When the significance of scaling test was observed for the characters than only the further analysis for gene action was done on six parameter model i.e., mean effect (m), additive gene effect(d), dominance gene effect(h), additive epistasis(i), dominance epistasis (j), additive dominance epistasis(l), all the six parameter was found significant for the characters plant height, number of seeds per spike in both cross I (CG 1608) and cross II (CG 1639), whereas some characters like number of spikelets per spike, number of seeds per plant and biological yield was significant for all six parameters only in cross I (CG 1608) . The duplicate type of gene action was showed by most of the characters in both the crosses.
