Retrospective study of methylmercury and other metal(loid)s in Madagascar unpolished rice (Oryza sativa L.)

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...

Red Strain Oryza Sativa-Unpolished Thai Rice Prevents Oxidative Stress and ACF in Rats

The bioequilibrium of antioxidant and prooxidant has a crucial role in cellular function with free radical defense (Valko et al., 2006). Oxidative stress is defined by the excess of free radicals and antioxidant depletion. It was implicated on biomolecules such as protein, lipid, and nucleic acid (Sies, 1997; Finkel & Holbrook, 2000). Cellular oxidative stress eventually caused tissue injury an...

Iron Bioavailability and Arsenic Uptake in Rice (Oryza sativa L.)

The extent of linkage disequilibrium in rice (Oryza sativa L.).

Despite its status as one of the world's major crops, linkage disequilibrium (LD) patterns have not been systematically characterized across the genome of Asian rice (Oryza sativa). Such information is critical to fully exploit the genome sequence for mapping complex traits using association techniques. Here we characterize LD in five 500-kb regions of the rice genome in three major cultivated ...

DIVERSITY ANALYSIS IN BORO RICE ( Oryza sativa L . ) ACCESSIONS

An experiment was conducted with 36 accessions of traditional (local) Boro rice germplasm accessions of three different groups (20 accessions as Kaliboro, 12 as Jagliboro and 4 as Tepiboro) during Boro season 2004 at BRRI farm to identify the duplicates with the help of morph-agronomic characters. On the basis of D values, the 36 genotypes were grouped into six clusters with a range of intra (0...
