Abstract
The objective of this study was identification of genomic regions controlling the flag leaf length (FLL) in Ds2 × RXL10 and 541 × Ot1-3 mapping populations of rye. Five QTLs (two on Ds2 × RXL10 map and three on 541 × Ot1-3 map) were detected on chromosomes 2R, 4R and 7R. Only the QTL on chromosome 2R was identified in the same region on both maps. The most important QTLs are located on chromosome 7R, but on different arms in each map. The coefficient of determination (R2) for QTLs ranged from 4.5 to 30.9%. The identification of QTLs can be helpful in explaining the genetic mechanisms of flag leaf development in rye.
