Performance 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.

Observed Benefits

  • Small tree, the smallest in the trials in fact and around 30% smaller than a HAES 246.
  • Possible low susceptability to Felted Coccid

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 Hidden Valley
  • Heat/dry stress observed at Hidden Valley

Gross Income per Hectare in Trials

RVT Series 3 (RVT3) was a multi-region trial conducted on behalf of the Australian industry. It included a total of 30 genotypes as follows

  • Five industry Standards. The Standards at most sites were HAES 246, HAES 344, HAES 741, HAES 816 and HV A16. The exceptions were at Wirrawilla HAES 246 and HAES 741 were swapped with HAES 842 and HV A268; at Childers HAES 344 was not available.
  • 20 industry selections
  • Five Hidden Valley selections A376, A403, A422, A447 and A538 discussed in these pages.

Using the basic measure of Gross Income/Ha/Yr calculated from RVT3 data years 4 to 9 as basis for comparison, HV A447 performed as follows

  • Averaged across all sites it was $1,795/Ha ahead of the Standards by year nine of the trials.
  • Ahead of the Standards at all sites except Booyan, Bundy Sugar, and Wirrawilla.
  • Acheived two site-specific Top 10 rankings, and an all-sites Top 10 ranking.
