Wheat production is often decreased by water limitation in world particularly in drought-prone environments. To map quantitative trait loci for grain yield as an important economic traits affecting wheat production, a recombinant inbred lines (RIL) population obtained from a cross between two spring bread wheats (Iran #49 and Yecora Rojo) was evaluated for grain yield and its components under well-watered and rain-fed conditions. Linkage map of the population was constructed using 203 SSR and retrotransposon markers spaning a total of 687.29cm of wheat genome with an average distance of 3.32cm between two adjacent markers. A total of 12 QTLs with LOD score from 2.5 to 4.5 (seven for well-watered and five for rain-fed condition) were mapped on six chromosomes for the studied traits. Out of these QTLs, 3, 2, 1 and 1 QTLs were identified for spike length (SL), gain number per spike (NG), grain yield (GY) and thousand kernel weight (TKW) under well-watered condition. Two QTLs for plant height (PH) and three QTLs for each NG, GY and TKW traits were also mapped under rain-fed condition. Detected QTLs explained from 7.78 to 13.89% of phenotypic variation. QTLs of GY and PH in rain-fed condition co-localized in same position.
