extremely significantp ≤ 0.001
A total of 12 lines showed extremely significant ( p ≤ 0.001) and stable higher SOC than recurrent parent ‘Emian22’ (Additional file 12 : Table S11), and 15 QTL were detected to be related to SOC using BLUPed data; of these QTL, 12 were firstly characterized and only two QTL for SOC have been reported previously in an interspecific population (Table 3 ) [ 43 ].
