Somaclonal genetics of rice, Oryza sativa L.
Theoretical and Applied Genetics, 1983The inheritance and variations of some traits of more than 2,000 somatic cell derived plants of rice (Oryza sativa L.) were investigated in the second and third generations (T2 and T3) of regenerated plants (somaclones). The percentages of multiploids occurring in somaclones ranged from 0-13.3 in nine varieties (or hybrids) of 'Hsien' (indica) group ...

Somatic Embryogenesis in Rice (Oryza sativa L.)
1995Cultivated rice belongs to the genus Oryza, in the grass family Poaceae (Gramineae). There are 22 species within the genus, 20 wild species and 2 cultivated species, O. glabberima (African rice) and O. sativa (common, or Asian rice).Oryza sativa is commonly divided further into two subspecies, indica (or tropical rice) and japonica (or temperate rice ...

Genetic Improvement of Rice (Oryza sativa L.)
2017The emerging challenges of increasing global population, decreasing arable lands, and escalating threats posed by climate change exert pressure on the genetic improvement of rice to increase its yield potential in irrigated and nonirrigated lands as it is the staple food of more than three billion people. Advances in genetics and molecular biology have

GENETIC ANALYSIS IN RICE (Oryza sativa L.)
Madras Agricultural Journal, 1987Genetic analysis of grain yield and yield attributes in rice, with 7x7 dialiel revealed that although both additives and dominance components are significant for all the characters studied, additive genstic component was predominant for plant height and grain yield and non-additive genetic components for days to flowering, productive tillers per plant ...

Cybridization in Oryza sativa L. (Rice)
2001Rice is one of the most important crops in the world, and feeds about 40% of the world population. The yield of rice needs to be increased, since a world food crisis has been predicted for the early 21st century. World annual rice production must increase from its current value of 520 to 810 million tons by 2025 (Hossain 1996).

CORRELATION STUDIES IN RICE (Oryza sativa L.)
Madras Agricultural Journal, 1988A study was made to find out the phenotypic correlation, correlation based you parents, correlation based on 'sca and heterosis of hybrids far, yield and yield components using 7-X 7 diallel. The results showed positive and significant association of productive tillers.

Linkage studies in rice (Oryza sativa, L.)
Euphytica, 1960Linkage studies in rice up to 1959 have been briefly reviewed with a special reference to the work carried out at the Central Rice Research Institute, Cuttack, India. The crossover values for several genes have been furnished. Instances have been cited wherein two or more genes appear to be involved in determining the expression of anthocyanin ...

Inorganic mercury accumulation in rice (Oryza sativa L.)
Environmental Toxicology and Chemistry, 2012Abstract To investigate the source and process of inorganic mercury (IHg) accumulation in rice, we monitored the concentrations of IHg in tissues of rice plants (Oryza sativa L.) from four experimental plantation plots. Biweekly during the rice-growing season, tissues of rice plants, corresponding soil, precipitation, and irrigation ...

RFLP analysis of rice (Oryza sativa L.) introgression lines
Theoretical and Applied Genetics, 1992Fifty-two introgression lines (BC2F8) from crosses between two Oryza sativa parents and five accessions of O. officinalis were analyzed for the introgression of O. officinalis chromosome segments. DNA from the parents and introgression lines was analyzed with 177 RFLP markers located at approximately 10-cM intervals over the rice chromosomes.

Origin of seed shattering in rice (Oryza sativa L.)
Planta, 2007A critical evolutionary step during rice domestication was the elimination of seed shattering. Wild rice disperses seeds freely at maturity to guarantee the propagation, while cultivated rice retains seeds on the straws to make easy harvest and decrease the loss of production.
