Banana ( AAA) is a world cultivated crop around tropical and subtropical areas. Low reproductive fertility and high polyploidy level makes difficult traditional hybridisation. Black Sigatoka disease caused by Morelet, is the most destructive disease and inveterate of this crop. Most research focuses on generating cultivars tolerant/resistant to this disease. Thus, radiation breeding could prove to be a viable method in banana breeding work. Carbon ion beam irradiation was applied to study critical doses, genetic variability and the response to black Sigatoka disease. Eight Gy was supposed to be the best dose to irradiate both banana cultivars. Eight plants were selected as possible candidates with a better response to black Sigatoka. In addition, a fast growing plant was observed and selected as earliness being an important characteristic for shortening the crop life cycle.
