The National Seed Industry Council (NSIC) said it approved 14 new inbred and dry-seeded rice varieties developed by the Philippine Rice Research Institute (PhilRice), International Rice Research Institute (Irri), and the University of the Philippines-Los Baños (UPLB) in 2015.
Among the newly released varieties, four inbreds—NSIC Rc394, Rc396, Rc402 and Rc414—and five dry-seeded—NSIC Rc416, Rc422, Rc424, Rc426 and Rc430—were developed by the PhilRice.
PhilRice said NSIC Rc394 or Tubigan 32 is an early maturing variety, with 106 days of maturity. It has an average yield of 5.2 metric tons (MT) per hectare across season.
NSIC Rc396 or Tubigan 33 has an average yield of 5.1 MT per hectare and 106 days of maturity, while NSIC Rc402 or Tubigan 36, has an average yield of 5.5 MT per hectare and matures at 107 days.
PhilRice Plant Breeding and Biotechnology Division Head Norvie Manigbas said breeding early maturing varieties is one of the strategies being carried out by the government as part of its climate-change mitigation efforts.
“The earlier the varieties mature, the earlier they are ready to be harvested. Our farmers can harvest and thresh the crop before strong typhoons or heavy drought come,” Manigbas said in a statement.
Meanwhile, NSIC Rc414 or Japonica 4, another inbred variety and a special-purpose rice, has an average yield of 3.7 MT per hectare across season and matures at 119 days. It has better resistance to common insect pests, according to PhilRice.
The PhilRice said the dry-seeded varieties in rainfed ecosystems, namely, NSIC Rc416 (Sahod Ulan 13), Rc422 (Sahod Ulan 16), Rc424 (Sahod Ulan 17), Rc426 (Sahod Ulan 18) and Rc430 (Sahod Ulan 20), are intended for pest-prone environments.
These varieties have higher resistance to common rice pests and diseases, such as bacterial leaf blight, blast, green leafhopper and white and yellow stemborer.
“Moreover, they have high-acceptability percentages, ranging from 81.7 percent to 96.7 percent, in terms of general consumer preference on grain and eating quality when cooked,” the PhilRice added.
Other varieties approved by NSIC were developed by UPLB (NSIC Rc398 and NSIC Rc418) and IRRI (NSIC Rc400, NSIC Rc420 and NSIC Rc428).
