QTL associated with shoot weight and associated marker effects. A. QTL on chromosome 2Â H with the peak LOD associated close to the APX gene. The qShW2H.1 and qShW2H.2 located at approximately 29.3 Mbp is closest to the ascorbate peroxidase gene which impacts abiotic stress such as drought. Interestingly, the marker 50k.2016.73569 corresponding to qShW2H.2 at 29.3 Mbp is located 850Â bp upstream of the Ascorbate peroxidase gene and 57kbp from Ppd-H1 gene which regulates barley flowering time during photoperiod response. Markers indicated in black bold corresponded to 1 LOD drop from the most significant QTL (indicated in red). B, C. Effect size plots of markers associated with shoot weight on chromosome 2Â H. Effect size plot for markers JHI.Hv50k.2016.73562 (B) and JHI.Hv50k.2016.73569 (C)
