Jambu CITRA aka Tong Sam See
Citra water guava was first introduced in Thailand in the 1990s. The Citra water guava was brought to Thailand by a farmer from Indonesia. After being introduced in Thailand, the Citra water guava quickly became popular among farmers and consumers and is known as the Tong Sam See water guava, which means “three seasons” because it can bear fruit all year round.
Currently, the Citra water guava is one of the most popular water guava varieties in Thailand. Widely planted in the northeastern region of Thailand, especially in the provinces of Nakhon Ratchasima, Chaiyaphum, and Khon Kaen. The northeastern region of Thailand has a climate that is suitable for growing Citra water guava, namely a tropical climate with a clear rainy season and dry season.
In Indonesia, Guava citra was first discovered by Dr. Ir. Moh. Reza Tirtawinata, an expert staff member at Mekarsari Fruit Park, Bogor, in 1990.
Initially, Dr. Reza found a water guava tree that had large, seedless fruit in Anyer, Banten. This tree is the result of a cross between local water guava and imported water guava from Thailand. Dr. Reza then carried out research and development on this tree for several years, and finally succeeded in producing a superior water guava variety.
Citra guava was officially released as a national superior fruit in 1994. Since then, citra guava has begun to be widely cultivated in Indonesia. This guava is also starting to be exported to various countries, such as Malaysia, Singapore and Thailand.
Citra water guava is a tropical plant with a tree habit that belongs to the Myrtaceae family (guava tribe). Citra water guava fruit has thick flesh, sweet taste, crunchy texture, high water content (juicy) and has no seeds.
Apart from that, the Citra water guava fruit is large, weighing 100-200 grams per fruit, but if the plant is cared for well, it can produce fruit weighing up to 200-350 grams. The water content of this guava is almost 93% in each fruit.
