Quality Aspects of Rice (Oryza sativa L.) and Rice Products

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...

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

Grain quality characteristics of Ofada rice (Oryza sativa L.): Cooking and eating quality

A study was conducted to evaluate the cooking and eating quality of Ofada rice. Quality parameters measured were; volume increase, grain elongation (GE), water uptake (WU), cooking time (CT), solids in cooking gruel (SCW), gelatinization temperature (GT) and amylose content (AC). The result showed that Ofada rice had high cooked rice volume with length and breadth increase of 152.54% and 87.85%...

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...

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 ...
