Oryza sativa or Asian cultivated rice is one of the major cereal grass species domesticated for human food use during the Neolithic. Domestication of this species from the wild grass Oryza rufipogon was accompanied by changes in several traits, including seed shattering, percent seed set, tillering, grain weight, and flowering time. Quantitative trait locus (QTL) mapping has identified three ge...

Black rice produces black which contains a lot of nutrients for the body, but there is still not much research done in increasing growth and productivity rice. The purpose this study was to determine level increase after addition phosphorus silica fertilizers varieties. experimental location Palir Village, Tengah Tani District, Cirebon Regency with height four 9 m above sea level. type soil all...

Amylopectin is one of the major determinants of rice (Oryza sativa L.) grain quality, and a large difference in amylopectin is found between two subspecies: japonica and indica. However, the relationship among rice grain quality, indica/japonica genetic background, and amylopectin has not been clearly established. In this study, a series of backcross inbred lines derived from the cross between ...

F1 hybrid sterility and "hybrid breakdown" of F2 and later generations in rice (Oryza sativa L.) are common and genetically complicated. We used a restriction fragment length polymorphism linkage map and F4 progeny testing to investigate hybrid sterility and hybrid breakdown in a cross between "widely compatible" O. sativa ssp. japonica cultivar Lemont from the Southern U.S. and ssp. indica cul...
