Comments about the QTL

Percent variance is in line with the results from other loci in the study

See original paper for specific results

The trait is resistance to Soybean Cyst Nematode ( SCN ) disease which is caused by the nematode Heterodera glycines. Study showed two different traits being defined (PA3 and PA14)
