Lam Dong perfected the breeding of clean and sick strawberries

Associate Professor, Dr. Duong Tan Nhut, Deputy Director of the Central Highlands Institute of Biology, said that after four years of research, so far has completed the process of breeding disease-free strawberries and providing large amount of seedlings for Strawberry growing area in Lam Dong.

All kinds of strawberries are clean diseases such as My Da, My Huong and Thom with a total output of about 305,600 seedlings through plant tissue culture method. When transferring the tissue plants to the nursery, the most suitable substrate is coconut fiber with a survival rate of 88.34%. The optimum growing conditions for propagation by cutting the stalks of strawberry plants are grown in plastic bags with five F1 seedlings formed on each mother tree.

Also according to Associate Professor, Dr. Duong Tan Nhut, after experimentally planting in some localities in Lam Dong in different forms such as on the suspension, in greenhouses, directly outside the nursery, the results obtained outside the garden is more choice. The average yield in a year is 57 tons / ha.

Since 2009, strawberries have fungal diseases, degenerative varieties and widespread destructive nematodes. The orchards of strawberries grow green, and when the period comes out, every green leaf suddenly turns purple and explodes, then it wilts to die. When the tree is pulled up, see the root system has a rotten phenomenon, causing hundreds of millions of VND damage to farmers. Epidemic diseases also cause strawberry prices to rise highly, sometimes increasing to VND 120,000 / kg.

Strawberries are one of the specialties of Dalat city, Lam Dong province, to eat fresh, processed jam and honey berries. Successful breeding, providing disease-free varieties of strawberries is very practical. At present, Tay Nguyen Institute of Biological Sciences has transferred the techniques of planting and taking care of disease-free strawberry varieties for farmers.
