Inheritance of resistance to bacterial blight in 21 cultivars of rice por Lee, K.S., Rasabandith, S., Angeles, E.R., Khush, G.S.

“…These cultivars were divided into two groups based on their reactions to Philippine races of bacterial blight. Cultivars of group 1 were resistant to race 1 and those of group 2 were susceptible to race 1 but resistant to race 2. …”

Domestic price distortions and agricultural income in developing countries por Bautista, Romeo M.

“…The static effects on agricultural crop production and income arising from the correction of three common policy biases in developing countries - the underpricing of food, agricultural export taxation, and currency overvaluation - are examined analytically and empirically (using Philippine data) based on a model of the agricultural sector with the food-export crop tradeoff in production as a key component. …”

Farm-level effects of irrigation system design and operation problems por Tabbal, D. F., Bhuiyan, S.I., Murray-Rust, Hammond

“…Specifically, it (1) describes the farm-level effects of design (and construction) and operation on the performance of irrigation systems; (2) identifies the factors leading to ineffective use of farm-level facilities by farmers; and (3) recommends additional criteria for the design and operation of irrigation systems. Arguments from Philippine case studies that evaluated alternative designs of farm-level facilities and approaches to improve equity in water allocation and distribution in a modern traditionally designed run-of-the-river, reservoir-backed, and pump-based irrigation systems are used.…”

Effector diversification contributes to Xanthomonas oryzae pv. oryzae phenotypic adaptation in a semi-isolated environment por Quibod, Ian Lorenzo, Perez-Quintero, Alvaro, Booher, Nicholas J., Dossa, Gerbert S., Grande, Genelou, Szurek, Boris, Vera Cruz, Casiana, Bogdanove, Adam J., Oliva, Ricardo

“…Here, we took advantage of an historical record to examine the adaptation pathway of the rice pathogen Xanthomonas oryzae pv. oryzae (Xoo) in a semi-isolated environment represented in the Philippine archipelago. By comparing genomes of key Xoo groups we showed that modern populations derived from three Asian lineages. …”

Are estimates of calorie-income elasticities too high? a recalibration of the plausible range por Bouis, Howarth E., Haddad, Lawrence James

“…Elasticities across four estimation techniques and four calorie-income variable pairs for a sample of Philippine farm households, ranged from 0.03 to 0.59. …”

Molecular characterization workflow of gene-edited rice lines: from development to securing non-transgenic status por Guevarra, Precious, Arcillas, Erwin, Matres, Jerlie Mhay, Enriquez, Blesilda, Kohli, Ajay, Slamet-Loedin, Inez, Trijatmiko, Kurniawan Rudi

“…Ensuring the presence of desired edits, verifying the editing system's accuracy, and securing non-transgenic status are all crucial in expediting development, Philippine regulatory compliance, and the eventual deployment of plants generated through genome editing. …”
