Comments about the QTL

Data are the means from 5 locations

DI is disease incidence, DS is disease severity

The disease SDS, sudden death syndrome is caused by the fungus Fusarium virguliforme (previously known as Fusarium solani). Study done by analysis of variance at locus; for purposes of display this was converted to an interval around that locus.

This locus associated with DI and DS
