Comments about the QTL

The trait is resistance to Soybean Cyst Nematode ( SCN ) disease which is caused by the nematode Heterodera glycines. This QTL was detected relating to resistance to the SCN isolate PA14, Hg type 1.3.5.6.7. Several pathivars were tested in this experiment. For further details, see the original literature.
