Newly developed varieties bring hope for the Australian purple passion fruit sector
The future of Australia's purple passion fruit industry is looking a little more colorful. Researchers have delivered the first new purple-skinned breeding varieties in more than 20 years, ABC News reported.
Researchers from the Queensland Alliance for Agriculture and Food Innovation (QAAFI) at the University of Queensland (UQ) presented nine of the 22 new selections at the Maroochy Research Center. The remaining cultivars continue to be evaluated.
Senior research fellow Mobashwer Alam identified the—provisionally named—UQP1 cultivar as a promising candidate because of its high productivity and extended harvest period.
"They start early and finish late, so the growers can collect and sell to the market for a long time," he told the local news outlet.
Australian passion fruit growers get first taste
The breeding efforts aim to replace the aging Sweetheart and Misty Gem hybrids, which have shown declining performance over the past decade.
According to the researchers, the varieties now produce smaller crops and have become more susceptible to pests and fungal diseases. This has even prompted some growers in southeast Queensland and northern New South Wales to leave the industry.
This is why growers and the Australian federal government funded the Hort Innovation breeding program to develop replacement varieties. The project stalled in 2023 after its original leader departed, but QAAFI assumed responsibility and resumed the work.
Passionfruit Australia executive and Tweed Valley grower Dennis Chant said the program has made great headway since then.
"The progress that UQ has made here over the last three years has been quite phenomenal," he said. “There's been a very structured scientific approach, and we're holding out high hopes."
Producers have begun testing the new selections under commercial conditions before deciding which varieties warrant larger-scale plantings. They also had the opportunity to assess the fruit for flavor, appearance, aroma, sweetness, acidity, and aftertaste.
Purple passion fruit production in Australia primarily supplies the fresh market, although fruit also serves the processing and juice sectors. Commercial passion fruit cultivation in Australia traces back to the late 19th century after the crop originated in Brazil's Amazon rainforest.
