Karninka Navel Field Day 13 September 2012

Produsente in die Groblersdal omgewing is baie in hulle skik met hul nuwe Lavalle aanplantings. Die bome het swaar oeste aan met uistekende vrug groottes.Die sukses van die aanplantings lok ad-disionele bestellings deur boere wat bein-druk is met die besondere vertoning van die variteit.

ARC BREEDING TEAM The South African Agricultur-al Research Council’s Institute for Tropical and Subtropical Crops (ARC-ITSC) has been involved in the breeding of new citrus varieties for the past 40 years. The ARC-ITSC Citrus Plant Improvement team is under the management of Arthur Sippel based at the ARC-ITSC in Nelspruit. The team is divided into different disciplines namely Breeding (Zelda Bijzet, Nikki Combrink & Sakkie Froneman), Evaluation (Johan Husselman, Christo Human, Johan Maritz & Lucio Zuma), Horticulture (Re-gina Cronje), Post Harvest (Sibongile Mhlophe), Biotechnology (Karin Hannweg, Anita Severn-Ellis & Gerrit Visser) and Germplasm (Theuns Anderson).

Citrus breeding at the ARC-ITSC involves conventional diploid crosses as well as induced mutations and triploid development. Breeding activities are located at two sites namely; the Addo Research Station in the Eastern Cape and Malelane Research Station in Mpumalanga.

Some notable successes coming out of this Breed-ing Program in the past years have been the X639 rootstock, 202H Shaddock, Eureka Seedless Lemon, NovaARC, B17 mandarin and Sonet.

Citrus breeding is a long term project and the breeding cycle can take up to 30 years from the time of making the cross until a successful vari-ety can be released, making citrus breeding very much a team effort.

B17 PLANT MATERIALThe first plant material of the GFMS12 mild strain isolate innoculated B17 mate-rial bore fruit at two Citrogold trial sites in the Eastern Cape this year.The first plant material of the new source has already been supplied to nurseries.Growers can expect to have their orders fulfilled with budwood supply form the CFB steadily increasing in volume over the next three years.The first B17 trees from this source will be planted in 2013.

KIWI FRUIT TOUR TO ITALY

Several South African growers will join an international group of aspirant Soreli Kiwi growers on a tour of the Italian Kiwi fruit industry in September.The growers that are participating in the tour are from Australia, Chile, China, New Zealand, South Africa, Turkey and the USA.

A R C C I T 1 6 1 4 The B17 mandarin receives a face lift - new name and re-lease of new plant material.

The B17 has been renamed the ARCCIT1614. The variety is protected by a PBR registered in South Africa and filed in a number of ter-ritories.

The variety has been under evaluation in a number of trial sites in the Western & Eastern Cape and Mpumalanga for the past 12 to 15 years. The variety has proved itself as a viable commercial variety and has been well received by the market.

The fruit ripens and is harvested in Mid July and enters the market in August. The ARC-CIT1614 produces good consistent crop loads year on year.

The variety is extremely tolerant of Alternaria as illustrated in the picture on the right.

information.

An initial target of 1000 ha’s was agreed upon by the ARC and the CGA. Growers have expressed keen interest in planting the variety and only a limited offering of hectares is still available to growers.

FUNNIESONLY IN AFRICA

A range of 15 blood orange and blood mandarin hybrids are currently under evaluation in 14 sites across the country. The evaluations are producing inter-esting and exciting results for the future. This evaluation program commenced in 2005 and is an ongoing project to provide safe planting guidelines to producers in the future.

The pigment in blooded citrus is caused by anthocyanin pig-ments which are water soluble and are stimulated to form in the fruit as a result of diurnal range and stress in late summer and autumn.

Citrogold evaluation of blood orang-es pays off

ClemenGold™ has featured in quite a few publications recently, amongst oth-ers Freshplaza, Fresh Fruit Portal and a ClemenGold™ promotion by Wool-worths.

An extract from Fresh Fruit Portal:ClemenGold mandarin exports to Eu-rope this season are on course to rise significantly this year with shipments to Germany and Austria up by 50%, and U.K.-bound shipments rising by 20%.

The trademark is collaborating with Spanish-based brand SanLucar who will act as the master agent in Germany and Austria, distributing the fruit to Edeka and Kaufland supermarkets.

ClemenGold chief executive officer Abs van Rooyen, said 200-300,000 15 kilo-gram boxes would be shipped to the two countries and alongside this a strong point-of-sale promotional campaign would be launched.

“This is significantly bigger than the pre-vious year. We are very excited about the potential to further establish the Clem-enGold brand with European customers.

“The forecast for this season looks good, with some high quality fruit coming from South Africa. We’re also expanding our supply base this season, with fruit from South America, Peru in particular.”

Velddae Noord Kaap

Citrogold in samewerking met Oranje Rivier Sitrus Kwekery en Neolandis het ‘n velddag gehou op 28 Junie 2012. Die suksesvolle bywoning wys op die feit dat sitrus produksie en veral kultivar keuses baie belangrik geag word deur produsente in die streek.

Die velddag het begin met ‘n boord besoek aan die oudste laat mandaryne, van dit onder verskillende nettipes by Karsten Boerdery en die eerste kommersiele Nadorcott boord onder net.

Verder was daar ook onderwerpe aangeraak soos goed-koper alternatiewe vir nette, oorsig op bemesting van Sitrus, biologiese middels om grond kwaliteit en opnames te verbeter en ‘n vruguitstalling van verskeie nuwe produkte wat deur Citrogold geevalueer word in die area, met die klem op mandaryne.

Die dag word die laaste twee jaar suksesvol gehou en die terugvoering is so positief dat dit ‘n jaarlikse instelling sal word.

Daar is ‘n velddag gehou in samewerking met Du Roi Kwekery by Schoeman Boerdery en Engel-brecht Trust op 10 Julie 2012 met die klem die keer op die Valencia reeks. Laat Mandaryn produsente het die nut uitgespreek om die 2012 seisoen meer te konsentreer op boord besoeke en praktiese kennis te kry as om te fokus op teoretiese praatjies.

Bywoning was uitstekend en produsente het selfs ingevlieg van ander areas om die velddag by te woon.

Die hoogtepunte was die produksie en vruggrootte van die reeks valencias soos Benny, Alpha, McClean SL en Lavalle en definitief die kwaliteit en eksterne kleur van Valley Gold bome, oudste in die area sowel as die manipulasie van Orri bome om vrugset te verbeter.

Die velddag sal weer gehou word in die 2013 seisoen om veral kumulatiewe opbrengste en kwaliteit te monitor.
