Effect of Gamma Irradiation on Fruits of Three Pepper Varieties Introduction The production of pepper (chile, bell and specialty-type) worldwide was nearly 200 million tonnes of green pepper and 33 million tonnes of dry peppers in 2013 (Naegele et al., 2016) .However, the global production of peppers was recently estimated at 14.4 billion dollars (FAO, 2016), approximately forty times bigger than what was obtained in the 80's.
