Variety - Hidden Valley A403

This page on Interpreting Varieties Pages provides information on the terms used below.


Note: A403 is South African Release Only

At this stage A403 & A422 will be South African releases only. The reason is that while they have performed well in trials, both late season harvest. Australia has recently added several new varieties with this trait in the last few years, so the market for them is probably already satisfied.

However, if there are Australian growers who would like to plant these trees, contact us and if enough are interested we can make them available.

A403 appears to perform well in most trial locations, but we are holding release in Australia due to its late harvest season.

Observed Benefits

  • Consistent performance across multiple sites

Observed Faults

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

  • Late harvest combined with low ethrel response.

Performance in Trials

In RVT Series 3 to year nine, A403 was ahead of the standards at Alstonville, DeCortez, Booyan, Bundy Sugar & Wirra Willa.

Using accumulated Gross Income per Ha as a comparator, on average it was $5,280/Ha ahead of the standards by year nine of RVT 3.

Note the following table uses mean annual Gross Income/Ha/Yr as opposed to accumulated value above.
