HIGH-TECHNOLOGY APPLICATION IN THE SELECT SIMILAR FRUIT: JACKFRUIT, DURIAN TREES, GRAPEFRUIT TREES GREEN SKIN AND BUTTER TREE.
 
On April 27 the year 2017 in the  breeder crop (Cho Lach district, Ben Tre) in combination with High Agricultural Technology Research Institute for Mekong delta (HATRI).   PROF. DR. Nguyen Thi Lang  breeder selective training and consulting for the 120 students of the Faculty of Agriculture Department of biotechnology An Giang University training for four groups of Jackfruit, Durian trees Trees trees, grapefruit Trees,  butter tree.

How  to development breeding for Citrus:  Blue grapefruit
Citrus scion breeding is a long-term projectfrom High Agricultural Technology Research Institute for Mekong delta (HATRI)because the process of producing new potential varieties and then evaluating them at several locations in Mekong delta  requires at least two cycles of tree propagation and evaluation:
The program focuses on new Blue grapefruittypes because these are increasingly important in the market, and many successful varieties have originated from breeding programs. The traits emphasized include excellent flavor, seedlessness, easy-peeling, high rind color, economic yield, and low tendency to alternate bearing. A minor focus is on grapefruit types, particularly a  lowacid type similar to grapefruittype(Blue skin).
Two major strategies are used: (1) development of low-seeded hybrids by crossing parents that produce triploids (like mutation; and (2) irradiation of budwood of seedy varieties of all types to induce mutations that confer low-seed content.
 blue skin of grapefruit trees a method of breeding clones from healthy shoots created roots quickly and create a new tree. For lemon orange, Tangerine and grapefruit group used the method of layering shortening the time for the left.
Development breeding durian at VietNam  
One of the ways to improve the quality of Viet NamDurian is by utilizing germplasm diversity.  Some durien have good smell at Cho Lach, Ben Tre. Durian is one fruit commodities that has an important economic value.  To improve the quality of  durian, cross breeding can be done by utilizing its germplasm diversity optimally.The simplest evaluation of genetic diversity is based on morphological characteristics (phenotype) which is easily observe, however it is very inadequate to differentiate genetically. This may caused by the fact that the species derived from strains from close family relationship often exhibit the same characteristics. In addition, plant breeders often find varieties with similar name but genetically may vary and are not even related, but it is difficult to distinguish phenotypically. Moreover, the phenotype is also affected by genetic factors and environmental conditions where the plant grows.
How to pair eye buds on the trees, plants and fruit trees Durian Fruit
This layering difficult plants must therefore use the method of grafting buds is the young shoots are picked from the leaf axils:-Twig branches are grafted grab "boring", stem diameter, stem from 8-12 mm. 
Note Select the clean spike disease.
 Technology “T” by high technology will root for graft survival rate of 99% for the surviving trees and fruit fast rate.
