Muhammad Sohail Mazhar of Pakistan was awarded a fellowship to do a PhD on avocado supply chains, at the University of Queensland. His specific area of research is investigating bruising of Hass avocados.
|Everybody loves a perfect avocado!|
About 80% of Hass avocados are bruised by the time they reach supermarket shelves, which puts many consumers off buying them. This is a significant problem in Australia, where the avocado market is rapidly expanding, with production projected to reach 65,000 tonnes in 2014, from just 46,148 tonnes in 2009-2010.

“Results so far indicate that the severity of bruising in ripening fruit increases with greater impact energy, particularly in softer fruits under ambient temperatures (other fruits, such as oranges, actually bruise more when they are hard). Using magnetic resonance imaging (MRI) to scan fruit and confirm damage by dissecting it reveals that bruises progressively increase in size for up to 96 hours following impact,” Sohail says.

So Sohail’s studies will next focus on the role of retail staff, shoppers and consumers on the bruising of ripening avocados.

The JAF fellowships are part of the Australian Government's Australia Awards program, which offers upcoming leaders from Australia and overseas high-quality education and professional development experiences that enable them to contribute to the development of their countries. Sohail has found the fellowship to be a rewarding experience, and is certain it has equipped him with the skills he would need to be a leader of international agricultural research back home in Pakistan.
Sohail says “Working together with public and private sector stakeholders has given me the ability to conceptualise, plan and execute multidisciplinary postharvest research focused on whole-of-chain challenges, including the important role of consumers. The experience I have gained through the JAF will benefit both Australia's and Pakistan’s horticultural industry.”

Sohail's research is using avocado as a proxy for mango, in ACIAR projects HORT/2005/157 Optimising mango supply chains for more profitable horticultural agri-enterprises in Pakistan and Australia and HORT/2010/001 Mango value chain improvement. These projects are part of the larger Australia Pakistan Agriculture Sector Linkages Program.
