Abstract:

0ryza minuta Presl., a wild rice species known to be resistant to bacterial blight and blast and green and brown planthopper, is endemic to the Malesian floristic region, specifically in Thailand, the Philippines, Indonesia, and Papua New Guinea. While it has been widely used in breeding and other experimental studies, its ecology and population dynamics remain poorly understood.

In 1980, Vaughan documented six populations of 0. minuta located along a stream in Barrio Balian, Pangil, Laguna. Seed samples from these populations were collected and later conserved at IRRI's International Rice Genebank.
