Abstract

In order to identify QTLs controlling traits related to spike population of 103 F3 and F4 family of barely derived from the cross of Badia and Kavir were assessed based on a randomized complete block design with three replications at the Agriculture and Natural Resource of Gonbad Kavous University in 2014 and 2016. The studied traits were a grains number in spike, spike length, spikelets in spike, total spike weight, total spike and awn length. Based on a composite interval mapping, nineteen QTLs were identified for the studied traits. Phenotypic variation that was explained by these QTLs, varied from 10-34%. The highest phenotypic variations were related to awn length and grains in a spike in the first and second year respectively. The Highest and lowest LOD scores were obtained for the QTLs of grains in the spike and spike length in the second year respectively. Negative and positive additive effects for identified QTLs showed the inheritance of favorable alleles from both parental lines to progenies in the detected loci. For the studied traits, five QTLs colocated for grain number per spike, spike weight, number of spikelets per spike, spike length and awn length. The markers showed tight linkage with major QTLs, could be used in marker assisted selection breeding programs for selection of superior family and incorporating of favorable alleles in to commercial Barley varieties.
