Mutagenesis of in vitro propagated bananas is an efficient method to introduce novel alleles and broaden genetic diversity. Mutations can be induced by treatment of plant cells with chemical mutagens or ionizing radiation. The FAO/IAEA Plant Breeding and Genetics Laboratory established efficient methods for mutation induction of in vitro shoot tips in banana using physical and chemical mut…
Bananas are a staple food for over 500 million people and are also an important cash crop. Fusarium wilt, caused by the fungus Fusarium oxysporum f.sp. cubense, is one of the most destructive diseases of banana globally. Since the 1990s, an aggressive variant of this fungus, called Tropical Race 4 (TR4), severely affected banana plantations in Southeast Asia from where it spread to other contin…
