Possible sources of resistance to black sigatoka in the Papua New Guinea biological foundation banana collection

摘要: Abstract Two hundred and sixtyfour banana clones, all but fourteen indigenous to Papua New Guinea, were assessed for their susceptibility black Sigatoka (Mycosphaerella fijiensis Morelet var. difformis Mulder & Stover). Assessments made during both wet dry seasons. Thirtyfive clones identified as having low levels of Sigatoka. Fifteen these are AA genome potentially useful in a breeding programme.
