Comments about the QTL
A Candidate_gene maps within 10 cM of the QTL. A Putative_candidate_gene is linked to the QTL, but more than 10 cM from it.
A006 the major SCN resistance locus in this study
Linkage group F in original paper
The trait is resistance to Soybean Cyst Nematode ( SCN ) disease which is caused by the nematode Heterodera glycines. Study done by regression analysis at locus; for purposes of display this was converted to an interval around that locus.
