Zespri has today announced the next stage in the recovery pathway from the devastating vine-killing disease Psa with the release of 2068 hectares of Gold3, a commercialised kiwifruit variety with tolerance to the disease.
Gold3 is a kiwifruit variety commercialised in 2010 after 10 years of development. It was selected from the extensive Zespri and Plant & Food Research new variety programme for its qualities of high orchard yields, handling characteristics, storage and positive appeal to consumers determined through in-market sensory work over consecutive seasons.
Zespri Chief Executive, Lain Jager, said the wide-scale release of Gold3 was significant for the New Zealand kiwifruit industry for two reasons.
Firstly, of the 2068 hectares of Gold3 released, 1610 hectares will be to Hort16A growers, starting the process of all Hort16A growers eventually transitioning their orchards to a more Psa tolerant Gold cultivar.
Secondly, this will be the largest transition to a new variety in a year that has ever been undertaken by the industry and represents the transition of almost 15 percent of New Zealand's kiwifruit hectarage to a new variety. The previous largest transition to a new variety was in 2000, with the release of 1200 hectares of Hort16A to the industry.
"The impact of Psa on the New Zealand kiwifruit industry has been devastating. Almost half of all New Zealand kiwifruit hectares now have some level of infection. With this transition to Gold3 we can see that around 1600 hectares of Hort16A canopy will be cut out as a result of Psa since November 2010.
"The announcement today is a significant turning point for our industry both in terms of beginning to emerge from Psa and in cementing the future growth of the industry," Mr Jager said.
