This new variety has the name of the red-fleshed pink dragon fruit 5. This is the first purple flesh dragon fruit variety that was first bred in Vietnam by scientists from the Southern Institute of Fruits (Vietnam Academy of Agricultural Sciences). The Cultivation Department (Ministry of Agriculture and Rural Development) has allowed extensive field trials in many provinces in the Mekong Delta and South East regions since December 2010.

Diversify dragon fruit

According to Dr. Tran Thi Oanh Yen, Institute of Southern Fruit, dragon fruit is a very valuable fruit, used to eat fresh or as raw material for export processing is very popular in the world. However, in Vietnam today there are only two varieties / types of dragon fruits grown popularly are dragon fruit White goose (Cho Gao and Binh Thuan) and Long Dinh 1 red dragon fruit, which do not meet the demand for diversification of chemicals. dragon fruit products on domestic and foreign markets.

Through the status of dragon fruit production in many localities, scientists from the Southern Fruit Tree Institute found that research on improving fruit yield and quality of dragon fruits in Vietnam is a necessary issue. Therefore, it is necessary to supplement new seed sources to diversify varieties of fruit trees in our country in general and high quality dragon fruits in particular.

Since then, in 2009 a group of scientists in the Department of Breeding and Breeding, Southern Institute of Fruit Fruits selected and conducted a sexual hybrid between dragon fruit variety Long Dinh 1 and dragon fruit white gut Cho Gao. After the evaluation of the quality of promising hybrid and hybrid dragon fruit fruit varieties for cultivation and use value trials, the group has released the first variety of purple-fleshed pink dragon fruit in Vietnam.

Productivity of 22 tons / ha

Scientists have put 11 hybrids into a field trial in three provinces of Long An, Tien Giang and Ba Ria-Vung Tau compared with two local varieties. After nearly two and a half years of growing trials, the purple-fleshed pink dragon fruit variety 5 gave satisfactory results because of the higher yield than the control dragon fruit samples (nearly 22 tons / ha), namely: high 5-10% more than Long Dinh 1 red dragon fruit (nearly 19 tons / ha) and 30-40% compared to Binh Thuan white flesh dragon fruit (over 13 tons / ha).

In addition, purple flesh dragon fruit gives a lot of fruit, averaging over 66 fruits / cylinder / year, the advantage over Long Dinh 1 red flesh dragon fruit only reaches 55 fruits and dragon fruit Binh Thuan white dragon only reaches above 50 fruits.

Mr. Nguyen Ngoc Thi, the head of the research team, selected and said: This variety has grown quite strong, producing flowers almost all year round. The fruit is quite big (over 380g / fruit), the shell color is quite beautiful and shiny; evergreen ears; fruits are purple and pink, quite firm, with little water, medium-sized seeds to good; In the first two crops, the survey has achieved a high rate of edible fruits and vegetables (74.68-75.41%); sweet and sour fruit (brix degree: 16.76; pH: 4.85).'In particular, the purple-pink dragon fruit variety has very few insect and disease diseases, especially anthracnose and black spot disease. Meanwhile, Long Dinh 1 red flesh dragon fruit usually infects ants and soot, white flesh dragon fruit is infected from low to moderate anthracnose and black spot disease in the same conditions as the trial . Speaking competition.

Dr. Tran Thi Oanh Yen, Head of Breeding and Breeding Department, Institute of Southern Fruit, said that the successful hybridization of the purple-fleshed dragon fruit variety 5 has opened up the prospect of a new source of export agricultural products. High economic value.

Currently, the research team has applied for registration of this variety at the new Plant Variety Protection Office (Department of Crop Production - Ministry of Agriculture and Rural Development) before making mass production in the coming time.'With the advantage of green ears, firm flesh, brittle and low water, fruit is less prone to cracking in the tree when ripe, so it can be preserved for a long time and sweet and sour taste. Consumers favor, farmers sell at high prices, bring big profits to dragon fruit growers .
