Selection of red rice (Oryza sativa L.) resistant blast disease

Morphology and Phenology of Putative Outcrosses Between Imazethapyr-Resistant Rice and Red Rice (Oryza sativa L.)

Red rice and rice belong to the same genus and species. Both are selfpollinated plants, but some outcrossing has been documented. Due to outcrossing, there are chances of resistant gene transfer from herbicide-resistant rice to red rice, which may increase the weediness of red rice. In 2000 simultaneous flowering was observed between Clearfield® CL2551 and red rice at the Rice Research and Exte...

Emergence of Red Rice (Oryza sativa) Ecotypes Under Dry-Seeded Rice (Oryza sativa) Culture1

The effect of seeding depth on emergence of red rice (Oryza sativa) ecotypes from Arkansas (AR), Louisiana (LA), and Mississippi (MS) was determined under dry-seeded rice production in clay and silt loam soils in Arkansas. By 21 d after planting (DAP), all red rice ecotypes had emerged from planting depths of 1.3, 2.5, 5.0, and 7.5 cm in both clay and silt loam soils. In silt loam soil, seedlin...

Straighthead Disease of Rice (Oryza sativa L.) Induced by Arsenic

Correlation Studies in Rice (Oryza sativa L.)

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...

Population structure analysis and association mapping of blast resistance in indica rice (Oryza sativa L.) landraces.

Rice blast caused by Magnaporthe oryzae is one of the most devastating rice diseases worldwide. To understand the genetic diversity of indica landrace accessions and identify simple sequence repeat (SSR) markers that are associated with blast resistance, a population of 276 indica landraces from across the world was constructed. This population was then used to evaluate the blast-resistance phe...
