Abstract/Summary Rootstocks can influence avocado fruit characteristics, including fruit resistance to postharvest rots and internal disorders. To evaluate the potential of selected rootstocks in Australia to improve fruit quality after cold storage, avocado fruit were harvested at commercial maturity from Hass trees grafted to several commercial and proprietary rootstocks at 3 sites in Queensland (Childers, Hampton and Walkamin) and one site in Western Australia (Pemberton) over 3 seasons. Fruit were held at 5°C for 4 weeks, and then ripened at 20°C with no ethylene, and quality assessed at eating ripe. Rootstocks significantly affected ripening time and flesh internal disorders, with the response varying depending on location and season. The proportion of sound fruit (i.e. <10% of the flesh affected by all internal defects) was also affected by rootstocks and varied by as much as 64% among rootstocks within one location and season. Diffuse discolouration, followed by vascular leaching were generally the main causes of quality loss.
