Avocado tissue culture propagation

Avocado tissue culture propagation

Avocado’s contribution to the global bioeconomy records a world production exceeding 5.9 million tonnes/year.

Meeting the plant supply for increasing demand has become challenging due to difficulty in rootstock propagation. Rooting an avocado cutting is cumbersome, thus has forced the industry to depend on genetically diverse and seasonally available seedling rootstocks for tree production. A tissue culture based clonal propagation system could provide a viable industry relevant alternative.

At the Queensland Alliance for Agriculture and Food Innovation, we have developed the world’s first successful pipeline for avocado tissue culture. With ARC-Linkage funding, our team of researchers, growers and the Queensland Department of Agriculture and Fisheries demonstrated complete proof-of-concept from Lab to Orchard.

Our system can produce up to 500 clonal plants from a single shoot-tip in culture within 8 - 12 months. Now, with funding from an Advance Queensland Innovation Partnership (AQIP), we have teamed with Central Queensland University (CQU) and the University of Southern Queensland (USQ) to deliver this technology.

1. A productive, competitive and sustainable avocado industry in Queensland

Potential for 3-fold higher yields with rapid multiplication of new cultivars coming from breeding programs and facilitate high-density orchards.

 

2. Export options

Early indications suggest demand from global nurseries for plants themselves, plus potential to reach >10% export goal of ‘Premium-Australian’ fruit through follow-on productivity gains.

 

3. Reduced environmental footprint

Significantly less inputs to propagation (water/ chemical/land/soil/plants) at reduced risk to industry (no dependence on seed/seasonality).
