RNA silencing has been regarded as a natural self-defense mechanism to protect plants from their pathogen invasion. Thus, there has been a variety of gene silencing strategies developed and exploited the natural pathway to generate virus-resistant plants. The newly developed artificial microRNA technology is generally recognized as an effective method of down-regulating target genes.

A total of 310  lines (BC₂F₂) derived from the cross of OM5930/N22 were evaluated for heat stress at flowering. Genetic map was set up with 264 polymorphic SSRs to detect linkage to the target traits. The map covers 2,741.63 cM with an average interval of 10.55 cM between marker loci. Markers associated with heat tolerance were located mostly on chromosomes  3, 4, 6,  8 , 10, and 11

The wild species of genus Oryza is regarded as a valuable resource for rice improvement because of its high genetic diversity. Chloroplast genome variations (maternal lineage) mentioning Oryza rufipogon populations collected were evaluated through 8 cpINDELs. 166 accessions from Vietnam comprises 10 plastid types, carrying 5 that were unique and different from the controls.

Dong Nam Bo (DNB) (South-eastern Region) is considered as one of the most favorable areas in the country to promote desirable crops, which are intensively grown for export purpose. Rubber, coffee, black pepper, cashew nut, maize, groundnut, and vegetable have been developed successfully.

P deficiency is considered as an important limitation of crop productivity. The lowland rice areas of Southern Vietnam as Fluvisols, Acrisols have been emphasized to be investigated how to improve the problem.

Information on genetic diversity among traditional varieties is critical in breeding programs as this influences parental selection in varietal development. A total of 100 traditional varieties in the genebank of the Cuu Long Delta Rice Research Institute (CLRRI), Vietnam, were used to explore this diversity using SSR markers.

Cassava bagasse is a fibrous residue obtained from the tapioca starch factories, which contains high starch and cellulose. In addition, it comprises some valuable components like proteins, pectin, lignin, fat, ash, and minerals.

OM 10041 was selected from a combination hybrid D23/C56. OM 10041  has the advantage of flexible and aromatic rice, short duration 90-95 days, hard stem, strong tillering, high yielding, especially in the winter-spring ranges from 6 to 8 tons/ ha, amylose content 20-21%.
