Functional Genomics-Assisted Development of Gene Markers for Economically Important Traits in Rubber Production Varietal Improvement

Rubber / By

Functional genomics involves studies on how genes and intergenic regions of the genome contribute to different biological processes. This is translated to the development of gene-associated molecular markers for utility in rubber production and breeding. Through functional genomics and bioinformatics, gene markers were generated using two approaches: a) genome filtering using methylation-sensitive restriction enzymes and …

Milkfish Synbiotic-enriched Feeds

Milkfish / By

The project aimed to address the current problems of the Philippine Milkfish Industry such as declining supply of stocks from the wild, high mortality rate, and the emergence of antibiotic-resistant bacteria through developing a novel dietary synbiotic product made from endogenous probiotics and under-utilized plant-based raw materials as prebiotic. Significant accomplishment of the project was …

Milkfish Core-Satellite Hatcheries

Milkfish / By

To address the shortage in milkfish fry for grow-out culture, aquaculture researchers adopted the milkfish hatchery core-satellite scheme adopted from milkfish hatchery operation in Gondol, Bali, Indonesia.  This scheme provides milkfish eggs for hatching to satellite hatcheries. The eggs come from a core hatchery that maintains the broodstock. The core hatchery sustains the milkfish satellite …

Automatic Fry Counter

Milkfish / By

The automatic fry counter is a laser fry-counting tool that addresses the problem of rigorous and inaccurate manual counting of milkfish fry. The tool was designed to minimize stress during the counting process and reduce the overall period of counting. The design for the automatic fry counter has been based on initial observations of fry …

Automated Mechanical top and Bottom Feeders

Milkfish / By

Automated and mechanized feeding systems are indispensable in smart aquaculture where precision and efficiency are imperative.  However, the adoption of highly-sophisticated feeding systems can be cost-prohibitive. Researchers have developed prototypes of automated mechanical top and bottom feeders at a cost of PhP10,000-12,000 per unit which is 50% cheaper than commercially available imported feeders. The automatic …

PCA-Recommended Coconut Hybrids and Cultivars for VCO and Coconut Sap Sugar

Coconut / By

Through the utilization of coconut genetic resources for high value products, best performing hybrids and varieties recommended for commercial production of coconut sap sugar and VCO were identified. The processing protocols from sugar grade toddy harvesting to sap sugar processing and packaging for commercial production of coco sap sugar were also optimized. Four hybrids (PCA …

Coconut genomics-Assisted Molecular Breeding

Coconut / By

The Coconut Genomics Program aims to improve coconut productivity through genomics-assisted marker selection for yield traits and molecular breeding of existing varieties. These include hybrid, on-farm selection, and economically beneficial cultivars. The program makes use of farmer’s field selections and selected coconut varieties, single-cross hybrids and advanced mapping populations of the Philippine Coconut Authority (PCA). …

Coconut Hybridization Program

Coconut / By
The Tacunan Dwarf x Laguan Tall (TACDxLAGT) hyrbids produced by the project thru assisted hybridization scheme in D’Farm, Brgy. Caldong, Sampaloc, Quezon.

Geared towards guaranteeing the production and ensuring sustainability of quality hybrids for the production of selected high-value products including coconut sugar, virgin coconut oil (VCO), and buko, the project titled Performance Evaluation of the 2-Pronged Coconut Hybridization Scheme in CALABARZON is being implemented by the Philippine Coconut Authority (PCA) – Region IV. The project is …

Coconut Somatic Embryogenesis Technology (CSet)

Coconut / By
CSet Cultures: A. Plumule-derived calloids; B. Somatic Embryos; C. Shootlet; D. Plantlet; and E. First fully-developed plantlet cv. Baybay Tall (BAYT)

The CSet Program, a 5-year program funded by DOST-PCAARRD, aims to mass propagate coconut planting materials using plumular tissues of identified tall, dwarf and hybrid varieties through coconut somatic embryogenesis. This program adopted the enhanced PCA-CSet protocol in seven (7) partner tissue culture laboratories that were upgraded for the protocol.  These laboratories are located in …

Biological Control of Coconut Scale Insects (CSI)

Coconut / By

Aspidiotus rigidus, an invasive pest commonly known as coconut scale insect (CSI) reached devastating outbreak levels in different areas in the Philippines, which is still a threat in other coconut areas in the Philippines as shown by the Species Distribution Model with high predictive power. Nevertheless, a native parasitoid Comperiella calauanica, first described in the …
