The issue, in Chile 2015, the WAPA forecast is. 167,000 tonnes
of fruit will be picked from Cripps Pink trees 60,000 tonne of this
will be sold as PINK LADY 107,000 tonne sold as something else
Around half of this (say 55,000 tonnes) may be sold as Cripps Pink
fresh apples Because of Internal Browning the remainder is likely
to be sold for juice, Other processing If this is correct, the
packout of PINK LADY apples is about 36% - NOT SUSTAINABLE, is
there an Answer? Pink Lady Apples Copyright 2008
Slide 3
Yes! Improved selections of varieties have been a key part of
the development process in the global apple industry for a very
long time. The Cripps Pink variety has created a number of new
mutations CPMs Pink Lady Apples Copyright 2008
Slide 4
How does a CPM become approved as a source of PINK LADY apples?
Pink Lady Apples Copyright 2008 In consultation with IPLA, APAL has
set criteria that a Cripps Pink Mutation (CPM) must meet in order
to be granted the use of the PINK LADY trademarks, they include: 1.
The variety is a mutation of Cripps Pink if its proven to be a
variety distinct from Cripps Pink by obtaining a grant of Plant
Breeders Rights (or Plant Variety Rights). 2. That the flavour,
texture, juiciness etc. of apples of the CPM are equivalent to that
of Cripps Pink apples and that this is demonstrated by properly
executed consumer evaluation experiments. APAL then enters into a
Variety Management Deed with the licensee for the CPM in the
territory.
Slide 5
Why do we do these tests? Pink Lady Apples Copyright 2008 We
want to be sure that: the new variety is distinct from, and
different to, Cripps Pink and that its adds some pomological
benefits to growers; We want to ensure that the new variety
maintains the eating quality of Cripps Pink, i.e. that there is no
drift in flavour and texture with the new varieties. What else is
achieved by introducing the CPMs to commerce? In licencing a CPM
variety the right to use the PINK LADY trademarks in a territory,
we are also able to: introduce planting disciplines related to the
volume of fruit to which the trade marks are applied in the
territory; require growers to pack all fruit of the variety that
complies with the PINK LADY quality standards as PINK LADY

The Cripps Pink Mutation (CPM) varieties: Pink Lady Apples
Copyright 2008 In Chile, three CPM Varieties are likely to become
approved sources of PINK LADY apples. They are: Rosy Glow:
Currently available in Chile via the Andes Nurseries Association
nurseries. Lady in Red: Not yet available in Chile but coming Ruby
Pink: Not yet available in Chile but coming

Slide 8
What benefit can the CPM provide to growers? Long periods of
warmer weather close to harvest usually result in lower colour
development, the APAL approved CPMs in general develop colour
earlier. Provides growers with a greater ability to pick the crop
in line with the PINK LADY quality specifications. Increased
packout of fruit that meets the quality specifications should
result in higher returns to growers. Pink Lady Apples Copyright

Slide 9
Possible grower strategies to maximise CPM opportunity Research
is clearly showing that fruit picked at optimum maturity is likely
to have less storage issues Orchard managers could be incentivised
to produce the crop to meet the PINK LADY quality specifications
by; Providing a monetary reward for fruit harvested at optimum
maturity. Pink Lady Apples Copyright 2008
Slide 10
CPM strategy cont/ Pink Lady Apples Copyright 2008 Harvest to
focus only on picking fruit that meets the PINK LADY quality
specifications. The example below is used in New Zealand This
systems provides a strong incentive to grow the crop to meet the PL
specs

is a commercial decision made by the grower based on the options
available in the territory.

Slide 14
Pink Lady Apples Copyright 2008 In Summary: The new CPM
varieties: Will likely colour to allow fruit to be picked at the
optimal maturity for the storage, shipping and distribution chain
the fruit will undergo. This means that using CPM varieties will;
Allow 60% of the crop to be harvested in the first two picks within
the optimal harvest window Potentially allow orchard owners to
offer their managers: incentives for achieving harvest within the
desired window
