Comments about the QTL

Parent_1 is PI437654, Parent_2 is Essex

The trait is resistance to Soybean Cyst Nematode ( SCN ) disease which is caused by the nematode Heterodera glycines. QTL is associated with resistance to SCN Races 2, 3, and 5

Publication used Female Index (FI) to quantify SCN resistance, where FI=(no. of cysts on individual/average no. of cysts on cv. Hutcheson)x100
