Abstract

In order to identify microsatellite markers linked to some traits of wheat under Drought Stress at the end of the season, the population included 96 family F2: 4 genotypes derived from the cross Kharchia (tolerant parent) and Gaspard (susceptible parent) were evaluated for 2 years. Of the 92 microsatellite markers used to assess parents, 32 markers were polymorphic that located on chromosomes 2B, 2D, 3B, 4A, 4B, 4D, 5A, 5B, 5D, 6B, 7A, 7B, 7D. Based on composite interval mapping was found 3 QTL for plant height trait which were located on chromosome 7B and the highest QTL with the largest LOD equal to 3. 21 was located between Xgwm274 and Xgwm369 and justified 14. 3 percent of phenotypic variation. For number of seeds per main spike trait, 1 QTL was detected on chromosome 2B and 1 QTL was identified on the chromosome 4B for harvest index trait. The common position of some of the located QTLs indicates a genetic linkage or pleiotropic effect. The saturation of the desired map and the evaluation of the stability of the studied traits can confirm the ability to identify the controller QTLs and provide the basis for Marker-Assisted Selection.
