Rainfed rice fields in the Philippines is estimated to be around 30% of the total rice production area and produce about 4.5 M mt of rice annually. Although most breeding efforts in rice are focused on irrigated rice agroecosystems, development of new cultivars for rainfed lowland rice areas is still pursued. The University of the Philippines Los Baños-Rice Varietal Improvement Team (UPLB-RVIT) has produced several rainfed lowland rice varieties over the years both for transplanted and dry-seeded culture. C9270-B-3-1-3-2 released as NSIC Rc 418 is the latest rainfed lowland rice variety developed by UPLB-RVIT for dry-seeding. C9270-B-3-1-3-2 is derived from a cross between C7652-2B-7-4 and C8212-B-1-2. It was identified as a promising line for dry seeding in the UPLB Preliminary Yield Trial (PYT), and was entered to the National Cooperative Test (NCT) in 2011. C9270-B-3-1-3-2 was evaluated for 4 wet seasons in 3 rainfed rice locations, and was recommended for release as NSIC Rc 418 or Sahod Ulan 14 in 2015. It is medium-maturing, semi-dwarf rainfed rice, with 13.1% and 18.9% yield advantage over check varieties PSB Rc 14 and NSIC Rc 192, respectively. It has intermediate reaction to diseases such as rice blast, bacterial leaf blight and sheath blight, has resistance to stemboreres and exhibits intermediate reaction to hoppers. NSIC Rc 418 also has excellent grain quality with good milling potential, intermediate amylase content (Value), and good acceptability in both raw and cooked form.
