The National Pineapple Breeding and Evaluation Program (PI17000) has developed promising new pineapple varieties with improved eating quality, disease resistance, and higher yields. Over five years, more than 35,000 seedlings were trialled, and advanced genetic analysis has refined the selection process, ensuring future varieties are better suited to Australian growing conditions. 

Challenge 

Australian pineapple growers face challenges related to fruit quality, yield, and resistance to environmental stressors such as natural flowering and disease. The primary challenges of the project included selecting pineapple varieties that balance improved eating quality with resistance to translucency and higher yields.  

Developing new varieties is a long and complex process, requiring extensive field trials, genetic analysis, and careful selection to ensure commercial viability. Additionally, ensuring that new varieties thrive across different Australian growing regions while maintaining desirable consumer traits presented a significant challenge. Without improved breeding strategies, the industry risked stagnation and reduced market competitiveness. 

Response 

In response to these challenges, the project implemented a comprehensive breeding program over five years, involving the fruiting of over 35,000 seedlings and the selection of 335 promising varieties. The project has leveraged advanced genetic analysis techniques, including the use of molecular markers and SNP markers, to identify traits of interest and improve the accuracy of selection.  

By leveraging new genetic data and field trial insights, the program established a strong foundation for further breeding, ensuring that Australian growers have access to high-performing pineapple varieties suited to both market and environmental demands. The project also focused on retaining and multiplying planting material from selected varieties to ensure their availability for further testing and development. 

Benefit  

This project has strengthened the future of Australia’s pineapple industry by developing new high-quality, high-yielding varieties tailored to local conditions. The use of advanced genetic tools accelerates breeding, reducing time to market for superior cultivars.  

Growers can expect improved fruit consistency, better disease resistance, and enhanced resilience to environmental stressors, leading to higher productivity and profitability. Additionally, the research outcomes support ongoing innovation, ensuring the industry remains competitive in both domestic and export markets.  

The availability of a diverse germplasm collection and a large population of new selections provides a strong foundation for future breeding efforts. Overall, the project supports the production of high-quality pineapples suited to the main summer production season, benefiting growers and consumers alike.
