The whiteness of cooked rice and rice cakes was evaluated using a portable spectrophotometer with a whiteness index (WI). Also, by using boiled rice for measurement of Mido values by Mido Meter, it was possible to infer the whiteness of cooked rice without rice cooking. In the analysis of varietal differences of cooked rice, 'Tsuyahime', 'Koshihikari' and 'Koshinokaori' showed high whiteness, w...

The study investigated socio-demographic factors and product attributes affecting purchase decision of special rice by Malaysian consumer. The primary data were analyzed by using binary logit model. Demographic factors and consumer preference for special rice (with reference to basmati rice) attributes were identified to affect purchasing behavior for special rice. Size of household, marital st...

High-temperature stress degrades the grain quality of rice; nevertheless, the exogenous application of plant growth regulators (PGRs) might alleviate the negative effects of high temperatures. In the present study, we investigated the responses of rice grain quality to exogenously applied PGRs under high day temperatures (HDT) and high night temperatures (HNT) under controlled conditions. Four ...

Although rice is a key crop species, few studies have addressed both rice seed physiological and nutritional quality, especially at the tissue level. In this study, an exhaustive "multi-omics" dataset on the mature rice seed was obtained by combining transcriptomics, label-free shotgun proteomics and metabolomics from embryo and endosperm, independently. These high-throughput analyses provide a...

Amylose content (AC) and viscosity profile are primary indices for evaluating eating and cooking qualities of rice grain. Using chromosome segment substitution lines (CSSLs), previous studies identified a QTL cluster of genes for rice eating and cooking quality in the interval R727-G1149 on chromosome 8. In this study we report two QTLs for viscosity parameters, respectively controlling setback...

Improving cooking and eating quality of rice is one of the important objectives of many breeding programs. The study of genetic diversity in specific regions of rice genome using molecular markers is an important index that can be used for the application of marker assisted selection (MAS) in rice breeding programs. In this study, 48 rice genotypes were grouped using 7 microsatellite (SSR) mark...

Sleeve and large field cage experiments were conducted in Stoneville, MS, in 2010 and 2011 to assess adult rice stink bug, Oebalus pugnax (F.), injury in rice. 'Cocodrie' and 'Wells' were infested at bloom, milk, and soft dough stages of panicle development. Twenty rice panicles were infested individually in the sleeve cage experiment as replicates with 0, 1, or 2 O. pugnax in a split-plot, com...

The Rice Genome Research Program (RGP) in Japan has been collaborating with the international community in elucidating a complete high-quality sequence of the rice genome. As the pioneer in large-scale analysis of the rice genome, the RGP has successfully established the fundamental tools for genome research such as a genetic map, a yeast artificial chromosome (YAC)-based physical map, a transc...

To investigate the motecular basis for the phenotypic diversity and evolutionary reltttionships within Ory7,a sativa, we performed large-scate end sequencing and chromosomal in silico mapping (mapping by sequence homology) ot' rice BAC (bacterial rtificial chromosome) clones derived from an indica rice cultivar, `Kasalath'. In total, 78,427 high-quality BAC-end sequences (BESs) showing an avera...
