QTL mapping of agronomical traits in Barley

In order to QTL mapping of agronomical traits in barley, experiment was conducted based in a randomized complete block design with three replications at research field of Gonbad Kavous University. Plant materials were 100 families of F3 barley derived from cross Badia × Komino cultivars. Analysis of variance showed  that difference of families all traits except spike weight and spikelet no./spike was positive and significant. Transgressive segregation was observed for all traits indicating  the presence of different allele combinations in the parents. Linkage map whit 7 (SSR) markers and 69 polymorphic alleles (iPBS) were prepared which covered 632.2 cM of  barley genome. In general, four QTLs were detected for traits number of seedlings, days to maturity, tiller number and spike weight. The maximum percentage of Phenotypic variance (R2) explained by QTLs was 11.4 percent. Review identified genetic locations showed QTLs of qNS-6, qTT-6 were co-localized.
