To determine mode of action of the genes affecting important agronomic traits and seed shattering resistance in soybean, progenies derived from crosses between Telar and T215, including F1, F3, BC1, and BC2 together with P1 and P2 were evaluated in Karaj. The results indicated that for all the traits, genes action with dominance effects, followed by additive effects had the most impact on the genetic performance. There was a high similarity in inheritance of the reproductive-related characters such as flowering initiation with starting stage of seed filling, completion of seed filling with seed maturity, seed yield with yield components especially with pod number per plant and plant height with number of node per stem. Dominance effects in seed shattering were more important than the additive effects. However, epistatic effects could not be ruled out. [d], [h] and [i] effects were significant for majority of agronomic traits and [j], [l] interaction effects were significant for a few traits. Inheritance mode of flowering initiation (R1) was similar to initiation of seed filling (R5), compelet seed filling (R6) was similar to compelet maturity (R8), seed yield was similar to its components and plant height was similar to number of nods. Seed shattering had single gene inheritance but different epistatic effects inpressed expersion of the character.
