To study inheritance pattern of threshability, two non-free threshing varieties of dicoccum viz., DDK-1025 and DDK-1029 crossed with advanced free threshable line NIDW-295. The non-segregating (P1, P2 and F1) and segregating (F2, BC1P1 and BC1P2) were developed and evaluated on individual plant basis for the trait threshability. The chi-square method was followed in order to test goodness of fit and establish gene relationship. Inheritance pattern of free threshability found to be governed by single dominant gene and free threshability is dominant over non-free threshability in F1 in both the crosses viz., DDK-1025 x NIDW-295 and DDK 1029 x NIDW-295. | Genetics of free threshability in tetraploid wheat
