Twelve (12) newly released and high yielding rice varieties are featured in the one-hectare President’s Farm of the University this 2021 wet cropping season.
The transplanting was led by the Philippine Rice Research Institute and Dr. Santiago R. Obien. Select Research and Extension staff of the University joined the ceremonial transplanting this July 29, 2021.
Five of these 12 varieties are inbred rice varieties while seven are hybrid rice varieties developed by PhilRice and other private companies. Inbred rice varieties include NSIC Rc 400 (Tubigan 35), NSIC Rc 402 (Tubigan 36), NSIC Rc 480 (GSR 8), NSIC Rc 508 (Tubigan 42), and NSIC Rc 512 (Tubigan 44). Hybrid rice varieties are NSIC Rc 204H (Mestiso 20), NSIC Rc 180H (Mestiso 15), NSIC Rc 406H (Mestiso 67), NSIC Rc 410H (Mestiso 69), SL 9H, NSIC Rc 488H (Mestiso 81), and PHB 73 (Mestiso 13).
The President’s Farm is located in the southwestern part of the College of Agriculture, Food, and Sustainable Development (CAFSD), just beside the seed production area of the University.
It can be recalled that the one-hectare demonstration farm was established in 2017 as a showcase of new and high yielding rice varieties released in the market. Through Dr. Obien, the 2017 ceremonial transplanting featured 14 that includes LP 331, NSIC Rc 400, SL 19H, LP 1232, SL 18H, TH 82, LD 937, NSIC Rc 390, LP 205, PNK 5017, NSIC Rc 396, LP 2096, and FS 6903. After four months, field tour in the different rice varieties to showcase their physical features as well as ceremonial harvesting with the President.
Knowing the rice Varieties.
The Department of Agriculture has been showcasing and featuring new and high yielding rice varieties in different locations. Through technology demonstration, they aim to encourage local farmers to adopt these high yielding varieties for higher productivity and higher income in support to the Masaganang Ani, Mataas na Kita goal of the Department of Agriculture.
The introduction and distribution of these varieties also form part of the Rice Resiliency Project (RRP) of the Department of Agriculture. It supports the agency’s Plant, Plant, Plant Program ‘Ahon Lahat, Pagkaing Sapat (ALPAS) kontra COVID-10. Additionally, the RRP links three sub-projects, to wit: RCEF-Enhanced, Expanded Inbred Rice Production (Beyond RCEF areas), and Expanded Hybrid Rice Production on Suitable Areas.
