Comments about the QTL
Locus K014 in original paper
Parent 1 is Peking, parent 2 Essex
The trait is resistance to Soybean Cyst Nematode ( SCN ) disease which is caused by the nematode Heterodera glycines. Study done by analysis of variance at locus; for purposes of display this was converted to an interval around that locus.
