Comments about the QTL
Parent_1 is Hartwig, Parent_2 is Y23
The trait is resistance to Soybean Cyst Nematode ( SCN ) disease which is caused by the nematode Heterodera glycines. SCN resistance quantified as an Index of Parisitism (IP) by counting cysts and females in a given plant/average number of cysts and females present in the susceptible parent
