In order to study the genetic conditions of some agronomic traits in wheat, a cross was made between Gaspard and Kharchia varieties. F2, F3 and F4 progenies with parents were evaluated under drought conditions. Threeparameter model [m d h] considered as the best fit for number of fertile tiller and flag leaf length using generations meananalysis method. For number of grain per spike and main spike grain weight three-parameter model [m d i] was used. For number of spikelet per spike, grain yield and plant height four-parameter model [m d h i] was used. The heritability values ranged from 56% for flag leaf length to 81% for grain yield. The F3 generation with 100 individuals was used to construct a genetic linkage map. Using the method of composite interval mapping 3, 1, 5, 2, 2 and 1 QTLs were detected for plant height, grain yield, number of spikelet per spike, flag leaf length, main spike grain weight and number of fertile tiller respectively.
