Comments about the QTL
Parent_1 is Hartwig, Parent_2 is Flyer
The trait is resistance to Soybean Cyst Nematode ( SCN ) disease which is caused by the nematode Heterodera glycines. Publication determined SCN resistance by Female Index, which was calculated as the number of cysts or females on a given plant divided by the mean number of the same on a susceptible cultivar
QTL was detected for resistance to HG Type 1.3.
