In rice breeding program, important genotypes are usually sourced out from the germplasm collections. The need therefore to continuously improve the gene bank holding through collection is necessary. An improved variety would not exist without the numerous predecessors that contributed to its development. Thus, the conservation and eventual utilization of traditional landraces as part of a crop's genetic resources is also important. Northeast Luzon (NEL) [Philippines] has a vast rice germplasms waiting to be explored. Three hundred sixty-nine traditional rice varieties from Region 02 [Batanes, Cagayan, Isabela, Nueva Vizcaya, and Quirino] and the Cordillera Administrative Region (CAR) [Abra, Apayao, Benguet, Ifugao, Kalinga and Mountain Province] have been collected to facilitate the discovery of desirable traits for abiotic and biotic stresses. Most of these materials have been characterized agronomically and based on yield and yield components. Some of them were selected for seed increased based on their performance, specially on yield and yield components, adaptation to adverse conditions and good eating quality (texture and aroma). The collected and characterized TRVs were submitted to GRD genebank to conserve its genetic makeup. These germplasms were seed produced and purified for future use and utilization of other institutions like SCUs and some have been utilized in the stations' hybrid rice breeding projects.
