Gummy Stem Blight Field Trial

We introgressed gummy stem blight (GSB) resistance loci from C. amarus, a crop wild relative of watermelon. This year we are evaluating these lines in the field!

First we grow a lot op plates of Stagonosporopsis citrulli, the main causal agent of GSB in Georgia. 

We then use a CO2 sprayer to spray the spores on the plants. 

We also installed a mist system to ensure the leaf surfaces stay wet to encourage spore germination.
