Abstract
Rice in the Philippines has traversed through ages in the archipelago. As country with extremely varied topography, the Philippines had a diverse reservoir of rice germplasm cultivated. This includes the traditional rice varieties (TRVs) or landraces that contains valuable genes that can be used to develop new varieties with improved yield potential, higher nutritional quality, and higher tolerance of the stresses for future climatic conditions. However, due to changing environmental condition and substitution of TRVs with modern varieties, rice diversity faced extinction through the years. Thus, the collection of rice germplasms has been a part of the continuous conservation effort at the PhilRice [Philippine Rice Research Institute] Genebank. From 2012 to 2017, PhilRice Genebank has managed to collect and conserve 4,053 rice germplasms, where in 49.29% was traditional varieties. It was followed by advanced/improved cultivars, breeding lines. farmer's lines, wild cultivars and unidentified biological classification which were mostly donated by farmers. Most of the collections came from Luzon (1,185) where the province of Nueva Ecija has contributed a total of 387 germplasms. On the otherhand, 443 rice germplasm collected from Mindanao and 135 germplasms from the Visayas. Currently, PhilRice genebank stores 16,298 rice collections, of which 7,129 were assigned as accessions. The collection of traditional cultivars and indigenous germplasm grown in various rice areas and deposited in a national genebak, will facilitate protection of genetic wealth as well as safeguarding Philippine germplasm's rich diversity.
