ANOVA

Hilum color weakly associated with SCN response
K069_1 now considered the most important SCN resistance locus (N. Young et al, personal communication
Resistant line M85-1430 assumed to be female parent;susceptible line M83-15 assumed to be male parent
Study done by analysis of variance at locus; for purposes of display this was converted to an interval around that locus.
The 3 loci A085, K069_1, and B032_1 show r2 of 0.59 in multiple regression (N. Young, personal communication)
The trait is resistance to Soybean Cyst Nematode ( SCN ) disease which is caused by the nematode Heterodera glycines.
