Details

A447 appears to perform well in most trial locations.

It was one of the top performers in RVT 3 despite being the smallest tree in the trials (~30% smaller than 246). Good performance with small tree indicates good potential for long term yield.

  • Small tree, the smallest in the trials in fact and around 30% smaller than a HAES 246.

Observed Faults

The variety is in very early stages of adoption, no obvious faults have been observed at this stage.

  • Canopy is a bit dense.
  • Trunk canker observed at Hodden Valley
  • Heat/dry stress observed at Hidden Valley
