New high-yielding rice varieties released
The multi-resistant Green Super Rice (GSR 8 or Rc480) stands out from 25 new rice varieties recently approved by the National Seed Industry Council (NSIC).
The new rice varieties were developed by the Philippine Rice Research Institute (PhilRice), International Rice Research Institute (IRRI), University of the Philippines Los Baños (UPLB), Philippine-Sino Center for Center for Agricultural Technology (PhilSCAT), Syngenta, and LongPing Philippines.
The Green Super Rice is resistant to multiple stresses such as drought, salinity, alkalinity, and iron toxicity. It can also grow under saline and drought-prone environments.
It has high yield despite lesser input. Its maximum yield is 4.4 tons per hectare and matures 107 days after sowing.
It is also resistant to pests such as yellow stemborer and brown plant-hoppers.
Dr. Oliver Manangkil, NSIC coordinator and head of the Plant Breeding and Biotechnology Division of PhilRice, said six of the newly released varieties are bred by PhilRice.
Manangkil said they are Rc440 (Tubigan 39), NSIC Rc438 (Tubigan 38), and hybrid Rc446H (Mestiso 73) for irrigated lowland; Rc472 (Sahod Ulan 22) for rainfed lowland; and Rc462 (Salinas 21) and Rc470 (Salinas 25) for saline environment.
He said Tubigan 39 can compete with hybrid rice varieties, giving a yield of 10.8 tons per hectare after 109 days of maturity. It also exhibits resistance to pest such as white and yellow stemborers and green leaf-hoppers (GLH).
