An investigation was carried out to elicit information on genetic variability and character association for yield and its component traits in 95 advanced generation free threshable mutant lines of derived dicoccum lines along with five checks (DDK1001, DDK1025, DWR1006, UAS415 and UAS304) of F4M4 progenies of wheat. The character starch content recorded least variability whereas, seed yield per plant (gm) and number of tillers per plant exhibited high variability. High heritability was observed in all the characters studied in the mutant lines. Yield per plant had a significant positive phenotypic correlation with starch content, wet gluten and sedimentation value.
