Target spot, or early blight, is one of the most common diseases attacking leaves and stems of tomato. Edgar Sierra Orozco is a National Association of Plant Breeders (NAPB) Borlaug Scholar and PhD Candidate in the Horticultural Sciences department of the University of Florida. He works at the tomato breeding lab at the Gulf Coast Research and Education Center under the guidance of Dr. Samuel Hutton. His project includes screening and mapping of resistance to target spot of tomato from several wild tomato species to ultimately provide the first ever target spot resistant tomato varieties. He sits down with Marc Zienkiewicz to talk about his work. Interview conducted this week at the NAPB annual meeting in Ames, Iowa.
