VEGETATIVE COMPATIBILITY AND DISTRIBUTION OF FUSARIUM-OXYSPORUM F SP CUBENSE IN AUSTRALIA

Isolates of Fusarinm oxysporum f. sp. cubense from wilted banana plant s in Queensland and New South Wales were characterised for vegetative compatibility. Six vegetative compatibility groups (VCGs) were identif ied. Race 1 (VCGs 0124, 0124/5, 0125) was widespread, being detected i n northern and southern Queensland as well as northern New South Wales . Race 2 (VCG 0128) was found attacking Bluggoe in North Queensland. R ace 4 (VCGs 0120, 0129, 01211) was detected in Cavendish plantations i n southern Queensland and in Lady finger plantations in New South Wale s and southern Queensland. Isolates of the race 4 VCG 0129 from Lady f inger plantations were pathogenic to Cavendish cultivars in glasshouse tests.
