2007-2008 Australia Season Update

-Bob Wickson, Regional Licensing Manager, Sun World Australasia

What a year of variables, severe drought in all areas with water allocations as low as 30% and the future looking bleak to severe floods, evacuation of towns and people being washed away. The latter was concentrated in North Queensland but a reasonable amount of this water flowed down the western part of NSW and gave good water to the grape areas of Mundubbera, St George, Bourke and Menindee. However our major grape area at Sunraysia misses this water as does the stone fruit areas. These areas did get rain but it fell in large lots just on harvest and caused splitting problems in both grapes and Suplumeleven.

Grapes 

Sugrathirteen, Mundubbra in December (click to expand)

This was the first year of harvest for most Sugrathirteen (MIDNIGHT BEAUTY® brand) crops and all growers were delighted with the yields 10-15kg [ 12-18  tons/ha]. Early harvest of Sugrathirteen from Emerald returned prices of AUD$50-60 for 5kg with berry size at 20-21mm. After recent rains this area has water for the next four years. Mundubbera had some of the best quality fruit of both Sugrathirteen and Sugraone (SUPERIOR SEEDLESS® brand) for many years and again prices were maintained to very good levels. Production at St George was set back due to an outbreak of Heliothis which caused damage to the bunches and then with wet weather fruit rots set in. Sugraone received the majority of damage. Water quality remained a problem in Menindee despite the heavy rains in the Queensland catchments area, as waters would not reach Menindee until after harvest. Water has been channeled into the lakes and at least the future looks brighter for these grape plantings, however it will take two years for the vines to fully recover. The Sunraysia area did not benefit from the Queensland rains but had heavy falls during harvest which caused huge losses in the Thompson harvest, berry splitting, ring necking. The Sugrathirteen harvest surprised most growers with 18 month old vines carrying 10-15kg [ 12-18  per ha) of fruit with berry size 16-18mm. While this fruit was out of QA specification it sold  AUD $5-7 above No1 grade Sugraone.

The West Australian grape harvest was the envy of all eastern state growers with prices for Sugrathirteen starting at AUD$100/10kg ctn and settling at AUD$80/10kg ctn. While some other varieties in the early areas of Carnarvon did return similar prices the yield of 20kg+ per vine  (24 tons per ha) for Sugrathirteen really created excitement.

BLACK DIAMOND® Brand Varieties

Suplumtwentytwo Nov 7 in Australia

Suplumtwentytwo (pictured) is proving to be a real surprise as we learn how to grow it. This season saw returns as high as AUD$50-60/5kg box and it retained an above $3/kg price for the season. Fruit size was excellent at 55 to 60+mm and growers allowed full colour to develop before harvest. The use of Retain® helped achieve this. Retain® also helped save Suplumtwentyfour which gave excellent outturns and returns for growers. This variety has been spared the chopping block. However Suplumtwentythree has disappointed again with very poor yields and fruit cracking. In some areas Bacterial Spot has also been a problem with this variety. The very hot conditions (43C) caused sunburn damage to Suplumtwentyfour , Suplumtwentythree , Suplumeleven (Suplumtwentytwo was harvested before the heat and there are only minor plantings of Suplumtwentyeight). Sunburn was more apparent on trellised trees where fruit was fully exposed. The heavy rain around the Suplumeleven harvest time caused skin cracking and Brown Rot infections. Packers who did not use fungicides or Chlorine at packing time suffered losses to decay.

Overall the season finished up being reasonable in view of the drought. Skin marks on Suplumtwentyfour and Suplumeleven remain a major problem causing down grading of 20-25% of harvested fruit. Next season blossom observations will be made from before flower opening to after petal fall using a microscope to identify any possible insect causes.

HONEYCOT® Brand Varieties

Suapriseven in packhouse, November

Apricot harvest went very well although it did appear at one stage that Suaprinine, in its first year on young trees, might not mature until after Suapriseven. However it matured very quickly and was harvested just ahead of Suapriseven. The Suapriseven harvest was excellent with fruit being marketed in punnets which sold very well, and looked excellent (see photo).

Suaprieight again caused problems  in the pack house  because of the skin bumps being damaged in the grading process. This variety  is now under question using existing fruit graders. Poppy will be used as a pollinator  for Suaprinine. 

 

New Zealand

The first commercial harvest of Suplumeleven was made in New Zealand this year. Fruit size and crop were excellent with fruit size being up to 80mm+. Harvest in the North Island commenced at the same time as Cobram in Australia, however the South Island harvest was up to one month later. Bacterial Spot remains a major concern for Sun World varieties with growers embarking on a Chlorine spray program similar to that used in Western Australia. Because of the Bacterial Spot on Suplumtwentythree in Australia its most unlikely that this variety will ever be planted in NZ. Both growers and consumers agree that Suplumeleven had superior taste however promotion will be needed to differentiate Suplumeleven from Black Amber. If Bacterial Spot can be controlled with Chlorine sprays NZ growers will plant more Suplumeleven .

Suapriseven apricot created excitement in the South Island due to its excellent size and skin blush. This variety will be planted if markets can be established in Australia.

The first plantings of Sun World grapes were made in 2007 and while only in test plantings there is excitement for the varieties.

2008 International Interns Appointed

Over the years Sun World has hosted interns from various countries and we are happy once again to be able to appoint internships for the upcoming season. Competition for internships has been strong and selecting two candidates from among such a great field is always difficult.

Raffaella Didonna

The 2008 Grape Internship was awarded to Raffaella Didonna from Bari, Italy. Raffaella works with Didonna Trade SRL as Quality, Organic Agriculture, and Marketing Manager. Didonna Trade is a respected company in the industry and Raffaella plays an important role in the areas of innovation and company relations. She manages the company's public relations and is a member of the Table Grape National Committee. She is also a qualified lawyer and is working to expand the scope of the company in several areas. One of those areas is the incorporation of new innovative grape cultivars and Raffaella has been instrumental in the testing and development of new Sun World table grape cultivars.

At Sun World Research and Development Center Raffaella will work with the breeder to coordinate field and post harvest lab data collection associated with commercial trials of new Sun World grape cultivars. She will also gain first hand experience working with the breeding programs, production managers and quality assurance personnel at Sun World.

 

Bob Wickson with Carla Fry

This year's Stone Fruit Internship was awarded to Carla Fry, from Como, Western Australia, who works with Mercer Mooney, a company that operates in Western Australia under the Montague Fresh Sun World license.  Carla grew up on a family orchard and currently works as Stone Fruit Ripening Coordinator for Mercer Mooney, selecting fruit for ripening and monitoring fruit ripening. She also evaluates different stone fruit varieties with respect to ripening potential and and provides reports to Montague Fresh.

At Sun World Research and Development Center Carla will coordinate post harvest evaluations of new stone fruit varieties in commercial test and in commercial trials, taking data on size distribution, defects, firmness and brix. During the time she is here Carla will also coordinate storage trials and participate in breeding population studies. 


 

2008 Fruit Season Begins in the Coachella Valley

Supechfifteen
AMBER CREST® Brand

The California stone fruit season begins with Sun World’s low chill* peaches in the Coachella Valley and that is a point of pride for manager Stuart Musashi and staff, Paco Hernandez and Romel Gomez, who manage Sun World’s earliest AMBERCREST® cultivars, Supechthirteen and Supechfifteen. Gomez, who has been helping to supervise the harvest noted the importance of experience when growing low chill stone fruit, “We have the earliest peaches in the country and we want to do it right and build our reputation with buyers,” adding, “The fruit hangs on the tree for only a short time and we want to peak on large 60’s and 50’s sizes (65-68mm) because the next smaller size can be $11-12 less per box. We thin fruit at the right time and leave the right amount of fruit per tree to get the best production and size. And then we make sure we pick at the right maturity to have the best flavor.”

Growing stone fruit in the Coachella Valley can be a challenge and Sun World’s stone fruit breeder, Terry Bacon noted that you have to have the right cultivars as well as the right grower to make it work. Bacon develops peaches nectarines and plums specifically adapted to low chill regions like Coachella. He also evaluates rootstocks for low chill regions and helps to develop management strategies there for optimizing production and quality. “Coachella is a desert, and conditions there are harsh.” said Bacon, “Stone fruit has gone in and failed in that region several times over the years, mostly do to poor cultivars, but also due to inexperienced growers. There is no getting it right 99% of the time because the region is so unforgiving. They have 4 months with average maximum temperatures over 100F (38C), and winters there might be great for tourists and retirees, but they are too warm for most stone fruit cultivars. We’ve had warm winters, no winter, sandstorms, and heat waves, but each season we improve a little bit more.” Bacon likes the Supechfifteen peach (pictured above) because of how it handles the harsh environment in Coachella, "It is great to see 3, 4, or 5 fruit on a hanger, all sizing up well; you don't see that with the earliest fruit in the SJV".

‘Dual-Use Cultivars’ grown in Coachella and the SJV.

Sunectwentyone
in Coachella Valley

Bacon has discovered that some of the new low chill cultivars developed for the Coachella environment perform very well in early areas of the San Joaquin Valley where they ripen about one month later. In fact Bacon found that many out-perform commercial cultivars developed specifically for traditional regions. “Coachella is a ‘trial-by-fire’ for new cultivars; they have so much environmental pressure put on them there that they really take off when planted in the SJV”, noted Bacon. “We are discovering incredible dual-use potential for many of our new low chill cultivars. For example Sunectwentyone nectarine (pictured) and PE216 peach perform well in both areas and we now have limited commercial production in early April in Coachella and in early May in the SJV for both. It’s like getting two cultivars for one,” said Bacon.

April 9th Fruit Trial now available on sunworldfruit.com

The Fruit Trial season has kicked off at Sun World with our first trial, held in a peach orchard in the Coachella Valley, showing peaches and nectarines. You must have a licensee user name and password to view and print the reports.

 

* Low chill refers to the low amount of winter ‘chilling’ temperatures (temperatures between 32-45F, 0-7.2C) required to satisfy a cultivar’s dormancy so that it can bloom and set fruit properly. Low chill cultivars require 100-200 chilling hours to come out of dormancy.
