Abstract

In order to identify QTLs controlling agronomic traits in 103 F3 families of Barley derived from cross Badia × Kavir was conducted based on randomized complete block design with three replications in 2014-2015 years, at the Faculty of Agriculture and Natural Resource of Gonbad Kavous University. For linkage map construction, 69 ISSR polymorphic alleles and 7 SSR markers were used  that covered 698 cM of the barley genome. 23 QTLs were identified. Among these mapped QTLs, qSW-3 (between ISSR29-7-ISSR31-5) and qSW-4 linked to (ISSR20-1), qSW-4 (between ISSR131-1-ISSR16-4), qSW-5 (between ISSR47-6-ISSR30-3), qSW-6 (between ISSR48-5-ISSR47-7), qSW-6 (between ISSR22-6-ISSR30-1), qSW-7 (ISSR48-1) for spike weight and qGL-4 (ISSR20-1) for grain length identified as major QTLs. It is suggested that Major QTLs should be considered in plant breeding programs and marker-assisted selection.
