Attempts has made to find the inheritance pattern of free threshability and other quantitative traits in emmer wheat has fragile rachis and non-free threshing kernels by crossing a non free threshing variety dicoccum DDK-1025, with two advanced free threshable mutant lines (ML-1 and ML-2) during Rabi 2013. Genetic systems operating in the both the crosses were found different for most of the characters as evident by differences in nature of gene action in these two crosses. Inheritance pattern of free threshability found to be governed by dominance gene effects with interaction effect (dominance x dominance). Presence of rachis is dominant to absence of rachis and it was controlled by single dominant gene. Number of tillers showed the predominance of additive gene action, most of the traits grains per spike, spike length, spike density and grain weight effects showed dominance gene action in one of the other crops. The role of epistatic components was indicated in the expression of plant height and grain yield per plant.
