Postharvest evaluation of FHIA-01 and other new banana varieties for subtropical Australia.

Promising new selections from overseas banana breeding programs are being tested in Australia as possible alternative cultivars for subtropical areas, where Panama disease (caused by Fusarium oxysporum f.sp. cubense) is becoming more widespread. The tetraploid hybrid FHIA-01 (SH-3481), popularly known as Goldfinger, performed well in agronomic and disease resistance trials in south-east Queensland and northern New South Wales (NSW). Its fruit quality and postharvest performance were evaluated in comparison with the 2 major banana cultivars grown in Australia - Williams (Cavendish, AAA) and Lady Finger (Pome, AAB). The studies examined optimum harvest maturity, green life, fruit respiration, responses to exogenous ethylene, fruit ripening characteristics, shelf life after ripening and market acceptance. The results showed that Goldfinger harvested at 3/4 full stage (36- to 39-mm grades) had adequate green life. Ripening at 16 deg C with high relative humidity levels (>96% RH), applying 1 ppm ethy

lene, gave fruits of the best appearance and colour. Judged by fruit appearance, Goldfinger and Lady Finger had longer shelf life after ripening than Williams, but Goldfinger fruits softened more rapidly than those of the other 2 cultivars. When finger drop occurred in Goldfinger it was reduced by harvesting fruits at a less mature stage or lowering the ripening temperature. There was a low incidence of ripe-fruit rots in Goldfinger.
