Nadorcott

ClemenGold Cultivar

• Nadorcott mandarins were originally selected for their easy peeling attribute and beautiful fiery colour.
• The smooth and slightly flattened rind is reddish-orange, and inside the fruit is a deep vibrant orange.
• One of the main attributes for inclusion in the ClemenGold brand is virtual seedlessness (a maximum of 5-10 out of a 100 fruit could carry a seed).
• At optimum maturity, they have a balanced sugar to acid ratio, high sugar levels (11% to 14% TSS) and moderate acid content (0.8% to 1.4%).
• In order to carry the prestigious ClemenGold brand, each fruit must have a perfect balance of sugar and acid, offering the consumer a lusciously juicy and subtly fragranced citrus fruit.

The Nadorcott journey
More than forty years ago Murcott seedlings were planted at the INRA experimental station near the small town of Afourer in the Atlas mountain region of Morocco. Growers soon discovered that Murcott fruit loses its seeded character when bees do not pollinate the trees, and so the Nadorcott variety was developed.

The cultivar rights to Nadorcott mandarins are managed by the Nadorcott Protection Company in Morocco for the Northern Hemisphere, and by Citrogold in South Africa for the Southern Hemisphere. Only Citrogold can legally grant licenses to growers in South Africa, Australia, Argentina and Uruguay. The company also controls production of the cultivar through contracts with growers. All import and export licenses are handled by a growers’ club.

Moroccan fruit is marketed as Afourer, after the initial INRA-W21 selection that later became known as Afourer. In South Africa, the ClemenGold® trade name is used, but only for the finest Nadorcott fruit that meets specific strict quality criteria.

The ideal harvesting time for Nadorcott mandarins in the Southern Hemisphere is from mid-June to mid-August, when they are perfectly ripe and at their sweetest. In South Africa ClemenGold is allowed to ripen naturally in the orchard before being picked and packed by hand. Strict packaging standards are applied to ensure its peak condition, from source to shelf. Northern Hemisphere fruit is usually ready for picking in March.

A typical Nadorcott orchard is beautiful with neat, evenly spaced rows of strong and proudly upright trees. They grow straight and fast like Murcott and so vigorously that they can easily reach a height of 2.5m in two and a half years. When fruit set, the tree canopy naturally opens up to invite sunlight. Nadorcott has a flowering time and intensity similar to Clementine, but it is not as prolonged as the Nule variety.

The rootstocks best suited to grow Nadorcott mandarins, are Carrizo, Troyer and C35 citranges. Nadorcott trees are very precocious and can deliver huge amounts of fruit in a fairly short time. It is not unusual that 5kg of fruit is set per tree at 18 months and 20kg per tree at 30 months. Trees between five and eight years old can each yield between 40kg and 100kg, depending on their size and spacing. Ideally, growers should produce between 45 and 55 tons per hectare.

Leanri Mandarin

Citrogold Cultivar

Following deregulation of the South African Citrus Industry in 1997, the previously, rather pedestrian pace of citrus farming has changed for growers and has become fast paced with more direct risks and opportunities.

Growers are now compelled to better acquaint themselves with the ‘marketplace’ and its numerous requirements. Factors such as fruit quality and taste, shape and size, colour and ripening periods can have a big impact on income and profit.

This has led to the introduction of many new cultivars.

One such exciting new cultivar is the Leanri mandarin hybrid, which is being commercialised by Citrogold in South Africa and Biogold International in other parts of the world. These companies are part of the ANB Group that is also renowned for the globally successful ClemenGold mandarin brand.

Leanri is an induced mutation of the Furr cultivar (Clementine x Murcott) and boasts a rich flavour, has deep orange external and internal colour, low seed content and easy peeling attributes. ‘Its ripening period is from the middle of May to the end of June in the northern areas of South Africa which places it in the mid ripening slot, starting at the latter end of the Nova and Clementine picking period and ending shortly after the commencement of Nadorcott harvesting.

‘The market increasingly expresses a preference for mandarins. A limited supply of great mandarin hybrids exists. ‘The Furr mandarin offers one of the best eating experiences and the challenge was to breed a seedless/low seeded, smooth skinned and smaller fruited version of the variety.’ One of the surprising results of the mutation was that the Leanri ripened nearly four weeks earlier than the Furr – a rare consequence of this type of breeding.

Technical insights
• The Leanri is a moderately vigorous tree with an upright to spreading growth habit with no thorns.
• Fruit has a deep-orange, fairly thin rind with relatively low oil content and is very easy to peel.
• Its shape varies from oblate and medium sized (calibre 2 – 1) to round and large (calibre 1X – 1XX) or extra-large (calibre 1XXX).
• A distinguishing characteristic is the open core.
• Fruit has high sugars, good acid levels and high juice percentages.
• Is low-seeded in solid blocks.

Leanri fruit was evaluated for suitability to cold sterilisation (-0.6°C) and cold storage (2°C and 4°C) temperatures for 30 days. The fruit was also evaluated for internal and external quality before cold storage, and again seven days after removal from cold storage (fruit was kept at 25°C to simulate typical shelf-life conditions). The fruit performed well at all temperature regimes with no external chilling injury, and minimal rind pitting or staining, while the internal quality remained good.

During the last 15 years Citrogold has licensed over 10 000 hectares of plantings of new cultivars in South Africa, thereby contributing significantly to the competitiveness of the South African citrus industry. Citrogold’s current product range includes citrus (oranges, lemons, mandarins, and grapefruit), pomegranate, mango, macadamia and passiflora.

Royal Honey Murcott (RHM)

The Royal Honey Murcott was a chance seedling that was discovered in an old orchard. We noticed that these honey murcotts were ripening an month earlier that our Low Seed Honey Murcott Mandarins.

Their superior taste, with high sugar and low acid, combined with this early timing made them perfect for our valued customers in Asia. The beautiful deep orange colour and smooth skin just adds to its appeal as the perfect mandarin.

For a first-hand account of this highly sought-after variety, Produce Report also spoke with Jing Huang, Assistant to CEO for Fruitday, a major Chinese fresh produce e-retailer, who confirmed the popularity of the Royal Honey Murcott in China.

“This will be our fifth year marketing this variety on our platform. In addition to maturing early, Royal Honey Murcotts also boast a good appearance, excellent taste, high brix, and low acid content. As a result, it has been received well on Fruitday and is a perfect fit for the Chinese market.”

Orri

Clementine & Mandarin

The Or, Orr or Orri is a late season mandarin with exceptional sweetness, but enough acidity to give a fine, well balanced flavour. Orri is mostly seedless and is a wonderful variety to extend the season of easy-peelers once the main clementine varieties have finished.

The skin is a lovely colour, being thin and quite easy to remove. There can be a slight oily residue on peeling, but really it is a sign of things to come.

At its best, Orri is simply irresistible with fine, juicy flesh and gorgeous sweetness.

Fine, sweet, balanced
Names: Or; Orr; Orri
Origin: Or is an Israeli variety from the famous Volcani Institute: an induced mutation of Orah, an Ortanique, which itself is a hybrid of Temple and Dancy.

Benefits of eating Mandarin Oranges

High in Vitamin C

Oranges are an excellent source of vitamin C. One orange offers 116.2 per cent of the daily value for vitamin C. Good intake of vitamin C is associated with a reduced risk of colon cancer as it helps to get of free radicals that cause damage to our DNA.

Healthy immune system

Vitamin C, which is also vital for the proper function of a healthy immune system, is good for preventing colds and preventing recurrent ear infections.

Prevents skin damage

Anti-oxidants in oranges help protect skin from free radical damage known to cause signs of aging. An orange a day can help you look young even at 50!

Keeps blood pressure under check

Oranges, being rich in Vitamins B6, help support the production of haemoglobin and also help keep blood pressure under check due to the presence of magnesium.

Lowers cholesterol

According to a study by US and Canadian researchers, a class of compounds found in citrus fruit peels called Polymethoxylated Flavones (PMFs) have the potential to lower cholesterol more effectively than some prescription drugs without side effects.

Controls blood sugar level

Fibre in oranges help by keeping blood sugar levels under control thereby making oranges a healthy snack for people with diabetes. Moreover, oranges have simple sugars. The natural fruit sugar in oranges, fructose, can help keep blood sugar levels from rising too high after eating. Its glycemic index is 40 and normally whatever foods fall under 50 are considered to be low in sugar. However, that does not mean you go about eating too many oranges in one go. Eating too much can spike insulin and may even lead to weight gain.

Lowers the risk of cancer

Oranges contain D- limonene, a compound that is touted to prevent cancers like lung cancer, skin cancer and even breast cancer. Vitamin C and antioxidants present in oranges are both important to build bodys immunity they help in fighting cancer. The fibrous nature of the fruit also makes it cancer protective. According to a study, up to 15 per cent of cancer cases happen because of mutations in the DNA, which can be prevented with Vitamin C.

Alkalizes the body

While the basic nature of oranges is acidic before you actually digest them, they have a lot of alkaline minerals that play a role in the process of digestion. This property of oranges is similar to that of lemons, which are without doubt among the most alkaline foods.

Good eye health

Oranges are a rich source of carotenoid. The Vitamin A present in them play an important role in keeping the mucus membranes in the eyes healthy. Vitamin A is also responsible to prevent age-related mascular degeneration, which in extreme cases can lead to blindness. It also helps eyes to absorb the light.

Safeguards against constipation

Oranges have both soluble and insoluble fibre. This helps in keeping your intestines and stomach function smooth, preventing irritable bowel syndrome. Additionally, the fibre helps treat constipation to a greater extent.
