Abstract

Based on feedbacks of development workers, local government units (LGUs), and agricultural extension workers, there are rice varieties unregistered to National Seed Industry Council (NSIC) and Philippine Seed Board (PSB). Some of these varieties are widely used by farmers and being preserved for years while others are introduced by fellow farmers from nearby Barangays [villages]. This study aims to identify unregistered rice varieties circulating in Negros and Bohol Islands, to document farmers’ reasons and socio-economic factors in using these varieties, and to collect seed samples for demonstration and classification study. Thirty-eight unregistered rice varieties were found in Negros and Bohol Islands and 52.63% of these varieties are used in Negros Oriental, 28.95% in Negros Occidental, and 18.42% in Bohol. The major reasons of farmer-users include resistance to insect pests and diseases, good eating quality and good germination. Minor reasons are higher grain weight, less fertilizer requirement, and tillering ability. Main and least socio-economic factors of using these varieties are easy accessibility and recommended by millers/traders having 61% and 2%, respectively. It is concluded that there are many unregistered rice varieties circulating and being used by the farmers in Negros and Bohol Islands. It is recommended that these varieties should be analyzed and characterized to check if these varieties are unique, NSIC and PSB released, or promising lines that were collected during field testing.
