Quantitative trait loci (QTL) that confer broad‐spectrum resistance (BSR), or resistance that is effective against multiple and diverse plant pathogens, have been elusive targets of crop breeding programmes. Multiparent advanced generation intercross (MAGIC) populations, with their diverse geneti...

Electron microscopic examination of thin section from rice hoja blanca virus (RHBV)-infected barnyard [Echinocloa colonum (L.) Link] revealed the occurrence of large masses of flexuous, tubular particles, 8-10 nm wide, both in the cytoplasm and nucleus. These inclusions were absent in cells from ...

Sixty rice cultivars were planted in 20 m long plant beds 1.20 m wide at two locations: Meta Department where good temperature and humidity conditions exist for blast (Pyricularia oryzae) development, and Cauca Valley where temperature is near optimum but humidity is low. At the Cauca location th...

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...
