Figure 2From: Association mapping and marker-assisted selection of the lettuce dieback resistance gene Tvr1Part of chromosomal linkage group 2, showing nine markers linked to the Tvr1 gene. The map on the left is based on segregation observed in the (Valmaine × Salinas 88) × Salinas population, the map on the right is based on segregation observed in the Salinas × UC96US23 population, and the map in the center is a consensus map developed from the two linkage maps. A black bar on the (Valmaine × Salinas 88) × Salinas map indicates the estimated position of the Tvr1 gene.Back to article page
