Promising new selections from overseas banana breeding programs are being trialed in Australia as possible alternative varieties for subtropical areas, where Panama disease 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 two major banana varieties grown in Australia, cv.
Williams (Cavendish, AAA) and cv.
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 ¾ full stage (36–39 mm grades) had adequate green life.
Ripening at 16 °C with high relative humidity levels (>96% RH), applying 1 ppm ethylene (trickle), gave fruit of the best appearance and colour.
Judged by fruit appearance, Goldfinger and Lady Finger had longer shelf life after ripening than Williams, but Goldfinger fruit softened more rapidly than the other two varieties.
When finger drop occurred in Goldfinger it was reduced by harvesting fruit at a less mature stage or lowering the ripening temperature.
There was a low incidence of ripe fruit rots in Goldfinger.
