Rice varieties that can withstand water-related stress bared
Philippine Rice Research Institute (PhilRice) developed some stress-resistant rice varieties that could effectively reduced the farmers’ problems about low yield.
Christopher Cabusora, a plant breeder of the PhilRice Plant Breeding and Biotechnology Division, said through th project “Rainfed-Stress Breeding”, PhilRice has produced rice varieties that are drought and saline resistant.
Now available for commercial cultivation, the drought-resistant varieties are: Sahod Ulan 2 with an average yield under stress condition of 3 tons per hectare, Sahod Ulan 11 (3.2 t/ha), Sahod Ulan 16 (3.4 t/ha), Sahod Ulan 18 (3.7 t/ha), and Sahod Ulan 22 (3.3 t/ha).
The saline-resistant varieties are: Salinas 6 (3.6 t/ha), Salinas 7 (3 t/ha), Salinas 8 (2.9 t/ha), Salinas 14 (2.3 t/ha), Salinas 213 (t/ha).
“These varieties are more advantageous (under stress environments) compared to common varieties because they can thrive under adverse environments, not to mention can give high yield for farmers,” Cabusora explained.
Cabusora also emphasized the importance of breeding stress-resistant varieties in helping the farmers enhance their yield in rice farming under stress condition.
“A farmer’s aim is to gain income, and as rice breeders, our goal is to help them achieve that by producing varieties like these. The best thing about these stress- resistant varieties is that whether there is stress or none, they can still produce yield no matter what,” Cabusora said.
There are also 11 stress-resistant mutant varieties from the Philippines that are registered on the International Atomic Energy Agency (IAEA) Mutant Variety Database (MVD). These are: BPI-121-407, PARC 1, PARC 2, BPI Ri-10, PSB Rc 78, Milagrosa mutant, Azmil mutant, Bengawan mutant, PR22902, NSIC Rc272 (Sahod Ulan 2) and NSIC Rc346 (Sahod Ulan 11). The last two varieties were bred by PhilRice.
