Sun World Technical
Support; Does it Work? |
The following is adapted
from an article that
examines the Sun World Technical
Support Program and highlights
success stories of the program.

the article in its entirety (pdf

Sugraone
(SUPERIOR SEEDLESS®)
had
become known in South
Africa and in many other
parts of the world as a variety
with low and inconsistent
yields. And the high percentage
of small and non-uniform
berries, that demanded high
labor inputs to trim out,
contributed to an already
doubtful reputation. In fact had
it not been for its earliness,
large berry size, crispy
texture, good eating and storage
qualities, this variety could
have been buried long ago.
Sun World, with decades of
production experience,
realized that prospective
producers should have access to
production technology required
to grow this variety
successfully. To turn the
negative impressions of the
Sugraone around, Sun World
needed to expose licensees
around the world to optimal
production practices to achieve
profitable yields of good and
consistent quality that is
typical for this variety.
In 1999 Sun World
instituted a
Sugraone advisory program
in South Africa, first by visits
to Sugraone growers by its own
viticulturists Kevin Andrew and
David Fenn, and later by
contracted consultants like
Hovav Weksler, Claus Orth
and Herbert Hattingh to
regularly advise Sugraone
growers on best production
practices.
Results
During this five-year
period from 1999 to 2003,
average national exportable
production increased 64% from
2,200 cartons (10 tons) per
hectare to 3,600 cartons (16
tons) per hectare (4,5 kg
equivalent). The top third
Sugraone producers today obtain
an average production of 4,200
cartons (19 tons) per hectare
and individual performances are
in excess of 6,000 cartons (27
tons) per hectare on an annual
basis.
Advisory
programs in other countries
In addition to South Africa
and Namibia, Sun World’s
advisory consultants are
continually exposed to Sugraone
production in various parts of
the world, including Brazil,
Argentina, Morocco, Egypt, Saudi
Arabia, Israel, Spain, Italy,
Australia and the United States.
Periodically, the information
and experience is pooled into a
Sugraone Production Manual
that details best production
practices as well as recommended
steps for establishing a new
Sugraone vineyard. These
guidelines are available to
interested licensed Sugraone
producers.

Report: Sun World
Early-Season Plums
-Terry
Bacon, Stone
Fruit Breeder |
Early-season
is our specialty and we
do a good job of combining
earliness with size in our fruit
breeding programs. For the
grower/marketer, that means
there are terrific opportunities
with early plums. This year is a
good example, with average plum
sizes being down in California,
early-season prices have been
above-average for larger-sized
fruit. Suplumtwentythree and
Suplumtwentyseven were standouts
for the Red Beaut-Black Beaut
window this year (see Seasonal
Shots for
Weeks
20-21).
Likewise Suplumtwentyeight and
Suplumthirtyfive have performed
well in the Santa Rosa-Black
Amber window this year (see Seasonal
Shots for
Weeks
22-23).

Mansour Assumes
Licensing Duties
for Chile & France
|
Andrew Mansour, a
four-year member of Sun
World's licensing staff,
has been named Regional
Licensing Manager for
Chile and France. He will continue
to be based at the
Company's Coachella,
California office and
assumes new expanded
responsibilities for all
of Sun World's
propagation, production
and marketing activities
in Chile and France.
Mansour also assists
management with various
special licensing
projects.
"These two countries
require special, focused
attention. With
Andrew devoting much of
his energy toward
developing new licensed
Sun World fruit production
in both France and Chile,
I know we'll provide even
better service and growth
opportunities to our
licensees," Senior Vice
President Licensing &
Corporate Development
David Marguleas said.

Report: 2004 Grape
Crossing Season
and Future Goals
of the Grape
Program.
-Michael
Striem, Grape
Breeder
|
We
continue to produce new
table grape offspring.
Annually we make crosses
between chosen cultivars
and selections aimed at
developing uniquely
designed, improved grape
selections. We are mainly
looking at the very early
and very late ends of the
season, but will also
challenge performance of
existing selections and
known varieties. Sun
World’s reputation of nice
looking grapes with
uniform large and firm
berries will be kept. We
do, though, continuously
add additional
characteristics such as
special shape, aromatic
flavors and resistances,
to our germplasm.
This year in the
third week of April,
we were already
at the
peak of our crossing
season, when many of our
grapevines flower.
Orchestrated by Gary Lott
(in photo on left),
Research Associate/ Vineyard
Manager, the
2004-program aims to make
about 150 different cross
combinations. The
expected seedling yield of
these should reach more
than 18,000 seedlings.
We were rushed into
this crossing season
about two weeks earlier
than usual due to
unusually high
temperatures; we were just
done planting seedlings
from the 2003 crossing
season. In each of the
past three years we
produced about 18,500
seedlings or a total of
more than 55,000 potential
cultivars. From these vines we have already made
many selections
which we are evaluating
for their commercial
potential as new
cultivars.
We have recently
invested many efforts
to improve our breeding
program to make it more
efficient. With focus on
quality, we have:
-
Introduced 6-week
post-harvest
cold-storage evaluation
to many selections.
-
Digital imaging of
selections and
cultivars, linked to the
breeding database.
-
Increased the cultivar
germplasm availability
to be used in breeding.
-
Improve our data
collection and database
management by converting
to a modern SQL server
platform,
Working closely with
our Cultivar Development
Specialist,
Guy McGhie, we hope to
be able to present to you
new selections every year.
