Four varieties released in 2011 were found to be tungro-resistant in Western Visayas, a study, which won the Best Poster Award under the rice breeding theme during the recent 26th National Rice Research and Development Conference, showed.
The study titled, Genotypic responses of newly released rice varieties to local rice diseases in Western Visayas, showed that NSIC Rc238, Rc278, Rc280, and Rc282 showed resistance against tungro in 29 sites. However, they are found to be susceptible to bacterial leaf blight.
Conducted from the wet season in 2012 to dry season this year, the study also tested six other varieties that were released since 2009. PhilRice, International Rice Research Institute, and University of the Philippines-Los Baños developed the varieties used in the study.
Researchers Cherry Endino, Dindo King Donayre, Ian Mark Ciocon, Jesiree Elena Ann Bibar, Edgar Libertario, Edgar Oyson and Manuel Olanday said that planting varieties suited in the locality is the first step in managing pests and diseases.
Meanwhile, Adaptation of recommended rice varieties to unfavorable agro-ecosystems in Ilocos by Anielyn Alibuyog, Jessica Solero, Raymund Rosales, and Mark Anthony Bartolome placed second under the same category. The On-farm seed storage system for farmers-saved seeds poster by Evelyn Gergon and Diel Donne Velasco placed third.
Under the theme, Pest management options for sustaining productivity and environment, the Rice black bug population and its natural enemies at different fertilizer levels by Shirley Balidiong, Hazel Anne Makahiya, and Rolando Cruz was adjudged as best poster.
Field validation of Trichogramma japonicum Ashmead against the white stem borer, Scirpophaga innota Walker in Agusan del Norte by BelenTabudlong and Gerardo Estoy Jr. and Biology of Paraeucosmetus pallicomis (Dallas), Hemiptera: Lygaeidae in Southern Luzon by Ma. Amabel Capricho, won second and third, respectively.
Isolation of Methanogens and Methanotrophs from a major tropical lowland rice soil by Jesiree Elena Ann Bibar and Bayani Espiritu; Enhancing soil water productivity for upland rice through CRH incorporation by Noel Ganotisi, Meljoy Gappi, and Marinelle Coloma; and Different rice varieties and promising lines have unique reactions to soil-limiting nutrients by Corsennie Mabayag and Regelyn Sobrevilla were the first three best under the theme Crop management options, farm mechanization, and energy generation for efficient and resilient farming.
On the other hand, Village-level production, integration, and utilization of VAM, Trichoderma sp. & NPV in rice-vegetable cropping systems by Jun Ramos, Salvacion Santiago, Gertrudo Arida, Belen Punzal, BM Shepard, and Gerry Garner; Hybrid solution using mobile apps for rice seed forecasting by Arturo Arocena, Jr., Jovino De Dios, Henry Cayaban, and Michael Malonzo; and Looking beyond rice farming: The VTEF model by Gilbert Romarez, Jo-Anne Lyn Joy Duque, Jose Nori Buhat, Mark John Ronolo, Janice Gaspan, and Rodolfo Escabarte Jr. bested other posters under the theme Systems and tools, technology promotion for increasing productivity, attaining food sufficiency, and competitiveness.
