QTL Analysis for Drought Related Leaf Traits in Doubled Haploid Populations of Barley (Hordeum vulgare L.)

Drought causes reduction in yield and its stability through simultaneous effects Oil Illany traits. Identification of genetic factors controlling these traits can lead to production or drought tolerant genotypes. One hundred and fifty eight doubled haploid lines with their drought tolerant parents ~WI71t)lxTudlnor) were evaluated in Tel Hadya and Breda with 100 millimeter differenceʹ in rninfa!l. They were planted ll~inlʹ an alpha-lattice dcsicn with 2 replications in each environment For subsequent employing in marker-assisted selection. number of QTLs. their genomic location, additive effects and the nearest markers were identified for pubescence. leaf senescence, and chlorophyll content. Linkage map »as constructed using 50 SSR and 93 AFLP markers and included R linkage groups 1()[ seven chromosomes. ()TL analysis was performed using composite interval mapping. Preliminary evaluation of the {rail ... were done with genetic corrclauon with grain yield
