Project Information


Note to readers, attached is the complete final report for FNE03-452.

The purpose of this project was to select heirloom tomato varieties for resistance to Alternaria blight and Septoria leaf spot. I planted six varieties in a plot designed to have heavy disease pressure (the "disease nursery") and selected the best-performing individuals from each variety. Seed from each of those individuals was then grown out in the disease nursery for re-selection in 2004. Indian Moon and Green Zebra were identified as already quite resistance to disease. Further selection needs to be down to improve disease resistance in Cherokee Purple and Pruden's Purple.
