Screening of 165 Papua New Guinea banana accessions for resistance to yellow Sigatoka (Mycosphaerella musicola Leach) in north Queensland

Papua New Guinea banana accessions were screened for resistance to M. musicola. Leaves were rated for disease on 3 occasions at monthly intervals to determine the youngest leaf spotted (YLS) and the youngest leaf with at least 33% of the lamina destroyed by disease (YL33). The YLS for the accessions ranged from 5.3 to 15.7 and the YL33 from 7.0 to 15.7. There was a considerable range of reactions to the pathogen with obviously resistant varieties in all genomic groups
