Significance

To help achieve a globally competitive and climate change-adaptive rice-based farming system in the Philippines, the UPLB-CA Rice Program undertakes the continuous development of varieties and technologies that will help enable farmers to meet the challenges of the rice industry. Aside from the development of adaptive varieties, there is a need to formulate innovative, sustainable, and competitive rice-based agricultural management strategies that farmers can employ. To make farmer-suitable technologies, the Rice Program researches are now engaged in participatory approaches on the development of dynamic, responsible, and sustainable agricultural communities.

Background

Since the period before WWII and years after, the Rice Varietal Improvement Program (RVIP) of the UPLB-CA Rice Program has conducted several breeding activities to improve commercially available varieties, as well as to select, or breed desirable lines from important pre-war varieties. The program has also amassed a huge volume of information related to rice breeding and production such as the discovery of wild rice species, hybrid vigor, genetic and inheritance studies, and pest resistance screening. It has also supported more than 100 thesis research studies on rice for undergraduate and graduate students at UPLB, covering a wide range of topics related to rice breeding and management. The program became a part of the Rice and Corn Seed Improvement Project in 1951, the predecessor of the National Cooperative Testing (NCT) Project,which facilitates the orderly varietal testing scheme in the country. 

Objectives

  1. Develop sustainable and climate change- adaptive farming technologies and approaches for rice production through rice varietal improvement and integrated crop management
  2. Enhance agricultural innovation through the participatory development of integrated rice-based agricultural system involving rice breeding, pest management, nutrient and water management
  3. Within the context of integrated rice-based production, to enhance community participation in local governance and decision-making

Thrusts

  • New technologies and molecular-based approaches such as marker-assisted selection to complement conventional breeding strategies in producing climate-resilient rice varieties
  • Rice production management practices that are suitable to constantly changing environmental conditions will also be formulated and tested in farmers’ fields 

Major Accomplishments

The program has assembled 849 accessions of traditional Philippine rice varieties and 35 accessions of four wild rice species. These are conserved at a short-term storage facility and are available to any interested individual. The program has also produced 32 commercial varieties since 1963, including the notable C4-63 or C4, a high- yielding irrigated lowland rice variety with excellent grain and eating quality. Other varieties developed by the program include:

  • Upland varieties - C22, C168, UPL Ri-1, UPL Ri-3, UPL Ri-5 and UPL Ri-7
  • Irrigated lowland varieties - UPL Ri-4, PSB Rc 22 (Liliw), PSB Rc 32 (Jaro), PSB Rc 58 (Mayapa), PSB Rc 74 (Aklan), NSIC Rc 144 (Tubigan 8) and NSIC Rc 156 (Tubigan 12)
  • Rainfed lowland varieties - UPL Ri-2, PSB Rc (Caliraya), PSB Rc 14 (Rio Grande) and PSB Rc 98 (Lian). PSB Rc 14 is a popular variety being milled as “Pinawa” or brown rice, while PSB Rc 98 is a widely grown variety in Northern Luzon Glutinous variety - NSIC Rc 13 (Malagkit 1), the first glutinous variety released by NSIC since 1985 Hybrids (in collaboration with PhilRice) - NSIC Rc 202H (Mestiso 19) and NSIC Rc 204H (Mestiso 20)
  • Most recent (2011) – rainfed lowland varieties NSIC Rc 272 (Tubigan 4), NSIC Rc 282 (Tubigan 7) and NSIC Rc 286 (Tubigan 9)
