CITY OF SAN FERNANDO – The Philippine Rice Research Institute (PhilRice) based in Nueva Ecija is now promoting a new and more high-yielding rice varieties that could produce six tons per hectare.
Thelma Padolina, division head of PhilRice’s Plant Breeding and Biotechnology Division, said the varieties are noted to yield one ton per hectare more than previous rice varieties being planted by Filipino farmers. She said they are suited for irrigated lowlands.
PhilRice is a government-owned and controlled corporation that aims at developing high-yielding and cost-reducing technologies so farmers can produce enough rice for all Filipinos.
Padolina identified the “inbred varieties” as NSIC Rc212 (Tubigan 15), Rcc214 (Tubigan 16), Rc216 (Tubigan 17), Rc222 (Tubigan 18), Rc224 (Tubigan 19), and Rc226 (Tubigan 20).
She said NSIC Rc212 matures within 111 and 115 days under direct wet-seeded and transplanted conditions, respectively. On the other hand, NSIC Rcc214 matures in 116 days when transplanted and 110 when direct wet-seeded.
Both varieties have resistance against brown plant hopper (BPH), green leaf hopper (GLH), and yellow stem borers (YSB), she said, but warned they are susceptible to tungro.
Padolina said that with an average yield of six tons per hectare, NSIC Rc216 and NSIC Rc222 are promoted for their moderate resistance against BPH, GLH, and YSB. However, they are likewise susceptible to tungro.
“Rc216 matures in 104 days when direct wet-seeded and 112 days when transplanted. Rc222 has maturity days of 106 and 114 when direct wet-seeded and transplanted, respectively,” she also noted.
Meanwhile, PhilRice also noted that NSIC Rc224 has an average yield of 5.7 to 5.8 tons per hectare across season and matures in 111 days. The long and slender grained-variety is moderately resistant to GLH, BPH, blast, and stem borer.
However, it is not for areas regularly stricken with tungro and bacterial leaf blight.
It said that on the other hand, NSCI Rc226 is also an early maturing variety that produces an average harvest of 6.2 tons per hectare across season. It matures in 112 days when transplanted and 104 days when direct wet-seeded. The variety is also moderately resistant to GLH, BPH, and YSB. Unlike other varieties, Rc226 could moderately withstand tungro attacks.
Foundation seeds of the varieties are available at Income Generation Office of PhilRice in Muñoz city in Nueva Ecija.
