Abstract
Six wheat genotypes viz; Nacozari, LLR-22, LLR-20, CB-42, Parula and LLR-21 screened for stem reserves mobilization efficiency were crossed in half diallel fashion. The parents and the F1 crosses were planted in the field in randomized block design with three replications. Two sets of this experiment were sown under rain-fed conditions; one was kept as untreated (control), while other was treated with potassium iodide at 50% anthesis stage to create chemical desiccation. Analysis of variance (combining ability) for treated condition showed significant results for general combining ability(GCA) and specific combining ability (SCA). GCA for all the traits under control condition was non-significant except for tillers per plant, while SCA values were significant for days to heading, plant height, grain per spike and yield per plant.
