Kiwifruit

Kiwifruit is a yummy fruit.

It grows on woody vines. The skin is light brown and fuzzy. Inside, it can be green or gold. It has rows of tiny black seeds. The fruit tastes sweet. Some kinds are even red inside! These fruits first grew in China. Now, many people eat them all over the world. Kiwifruit is a fun treat to eat.

Kiwifruit grows on woody vines.

These vines climb and grow quite fast. Most kiwifruit comes from the genus Actinidia. This is a group of plants that includes many species. Many people know the fuzzy green kind. This variety is called Actinidia chinensis var. deliciosa. It is egg-shaped with brown, fuzzy skin. The inside is bright green with tiny black seeds.

Another kind is the gold kiwifruit. It has smooth, bronze skin. The flesh can be bright green or intense yellow. These are often sweeter than the fuzzy kind. Some gold fruits even have a red ring in the middle. There are also kiwiberries. These are small, like a large grape. They have smooth skin and taste like regular kiwifruit. Kiwifruit first grew in China. People in China have known about them since the 12th century. Today, China is the largest producer in the world. They make 55% of all kiwifruit.

Kiwifruit is a delicious berry that grows on woody vines.

Most of the fruit we eat comes from the genus Actinidia. This group of plants includes many different species. The most common type is the fuzzy green kiwifruit. This variety is called Actinidia chinensis var. deliciosa. It is oval and shaped like a large hen's egg. The skin is light brown, thin, and fuzzy. Inside, the flesh is light green with rows of tiny black seeds.

Many people also enjoy the smooth gold kiwifruit. This variety is called Actinidia chinensis var. chinensis. It has bronze skin and a sweet, aromatic flavor. Some gold varieties even have a red ring around the center.

Growing these fruits involves many different steps. The plants start as fast-growing vines that climb upward.

In places like New Zealand, growers use special practices to help them thrive. They must manage the plants through different seasons to ensure a good harvest. Some varieties, like 'Blake', can even self-pollinate to make more fruit. Other types, like 'Issai', are hybrids made by crossing two different species. This helps create plants that are larger or easier to grow. Scientists work hard to breed new versions that taste better or resist diseases.

Kiwifruit has a very long history. The fruit is native to central and eastern China. A poem from the Tang dynasty even describes a similar plant. The first written description dates back to the 12th century during the Song dynasty. In the early 20th century, the plants moved from China to New Zealand. During World War II, British and American servicemen in New Zealand discovered them. By 1953, they were being exported to the United Kingdom and Australia. Later, in 1959, they reached California.

Many interesting facts exist about this fruit. In 1959, the name "kiwifruit" was officially registered by Turners & Growers. They chose this name because it sounded better to American clients than "Chinese gooseberry."

Today, China is the largest producer in the world. As of 2023, China produces 55% of the global total. The Wuhan Botanical Garden in China holds a huge gene bank for these plants. It protects 73 different varieties and 426 high-quality strains. Some special types, like 'Hongyang', have even been bred to have red flesh.

Learning about kiwifruit helps us see how plants connect the world. You might see "kiwi" used as a nickname for people from New Zealand. You might also know the kiwi as a furry brown bird.

Even small "kiwiberries" are part of this plant family. They are the size of a large grape and have smooth skin. Whether you eat a large fuzzy fruit or a tiny berry, you are tasting a plant with a global story. It is a fruit that traveled from ancient Chinese forests to grocery stores everywhere.

Kiwifruit, often called kiwi, is the edible berry of several woody vine species within the genus *Actinidia*.

These plants are significant because they have moved from wild Chinese forests to become a massive global agricultural industry. While the genus contains approximately 60 different species, most commercial fruit comes from just a few specific types. Understanding kiwifruit requires looking at its diverse biology, its complex history of naming, and the scientific breeding that defines modern varieties.

The most recognizable variety is the fuzzy green kiwifruit, known scientifically as *Actinidia chinensis* var. *deliciosa*. This cultivar is typically oval and roughly the size of a large hen's egg. It features a thin, light brown, and fibrous skin that is edible despite being tart. Inside, the fruit has light green flesh arranged with rows of tiny, edible black seeds.

Another major group is the golden kiwifruit, or *Actinidia chinensis* var. *chinensis*. These fruits have smooth, bronze skin and a beak-like shape at the stem. Their flesh can range from bright green to intense yellow, and they are often sweeter and more aromatic than the fuzzy variety.

Kiwifruit cultivation involves various distinct types and hybrids. Some species produce "kiwiberries," such as *Actinidia arguta*, which are the size of large grapes. These have smooth, thin skin and are described as fast-growing, climbing vines.

Scientists also create hybrids to combine the best traits of different species. For example, the 'Jinyan' cultivar is a hybrid of *A. eriantha* and *A. chinensis* var. *chinensis*. Another hybrid, 'Issai', combines *A. arguta* and *A. polygama* to create a larger fruit that can self-pollinate, though it is less hardy than most *A. arguta*.

The history of the kiwifruit begins in central and eastern China. The first identifiable description of *Actinidia chinensis* appears in a Tang dynasty poem by Cen Shen, which describes a plant growing near a well in Shaanxi. The first formal recorded description dates back to the 12th century during the Song dynasty. For much of history, the plant was collected from the wild for folk medicine rather than being farmed. In the early 20th century, cultivation spread from China to New Zealand, where the first commercial plantings occurred.

During World War II, British and American servicemen stationed in New Zealand helped popularize the fruit.

The name "kiwifruit" has a fascinating origin story involving international trade and quarantine laws. In the 1950s, the fruit was commonly known as the "Chinese gooseberry." However, a New Zealand exporter named Norman Sondag suggested a name change to avoid quarantine issues in the United States. He believed officials were suspicious of "gooseberry" shipments due to fears of soil contamination from *Bacillus anthracis*, a bacterium that causes anthrax.

Jack Turner of Turners & Growers coined the name "kiwifruit" to appeal to American servicemen, referencing the informal name for New Zealanders. The name was officially registered on June 15, 1959, and became the standard for all New Zealand exports by 1970.

Modern kiwifruit production is a massive global enterprise with significant economic numbers. As of 2023, China is the world's largest producer, accounting for 55% of total global production. While the 'Hayward' cultivar was once dominant, China has developed many domestic varieties. By 2020, 'Hayward' made up only 6.3% of Chinese plantings as local cultivars like 'Hongyang' and 'Donghong' gained prominence. China also maintains the world's largest kiwifruit gene bank at the Wuhan Botanical Garden. This facility protects 73 validated varieties and 426 high-quality strains to ensure future breeding success.

Kiwifruit connects various fields of study, from botany to international law. In biology, the study of *Actinidia* germplasm helps scientists understand plant evolution and disease resistance. For instance, when the PSA bacterium caused losses to golden kiwifruit in New Zealand between 2010 and 2013, breeders developed the 'Gold3' cultivar to be more resistant.

In the legal field, the industry involves complex intellectual property battles. Zespri, a major New Zealand brand, has engaged in legal efforts in China to protect the intellectual property of its SunGold clones. These efforts highlight how a single fruit can link agricultural science, global trade, and international law.
