Red rice (Oryza satlva L ) has been a serious problem in rice fields for hundreds of years and even now no effective control measure exist. In this study, new approaches were evaluated. Flooding for two weeks prior to seeding IR-22 eliminated 99 percent of the tall variety Bluebonnet 50, which ha...

Rice is the most important food crop in the developing world. For rice production systems to address the challenges of increasing demand and climate change, potential and on-farm yield increases must be increased. Breeding is one of the main strategies toward such aim. Here, we hypothesise that c...

The paper uses the average treatment effect (ATE) to estimate the population potential adoption rates of the New Rice for Africa (NERICA) varieties in Nigeria when awareness and access to their seed are not constrained to farmers. It thus extends previous works in the literature that have focused...

Subgenomic RNAs of both polarities corresponding to rice hoja blanca virus (RHBV) ambisense RNA4 were detected in RHBV-infected rice tissues. Total RNA extracted from RHBV-infected and noninfected rice tissues and RNA4 purified from RHBV ribonucleoprotein particles were used as templates for prim...

Ninety-five strains of fluorescent (presumed to be Pseudomonas spp.) and nonfluorescent pathogens of rice causing grain and sheath rot, dirty panicle, and manchado de grano, and 21 strains of nonpathogenic fluorescent pseudomonads isolated from rice grain and sheaths from 22 countries were compar...

Rice Breeding Program (RBP) of the Instituto de Investigaciones Agropecuarias (INIA) at Chillán, Chile, has a rice (Oryza sativa L.) germplasm collection that consists of 1200 accessions, mainly temperate japonica rice accessions, well adapted to the local conditions. Most of the new introduced a...
