Understanding the basis for intraspecific yield variability may be important in elucidating biological mechanisms that are associated with superior yield performance in response to projected increases in carbon dioxide concentration, [CO₂]. Using a free-air CO₂ enrichment (FACE) facility, two rice lines, S63 and W14, which differed consistently in their enhancement of seed yield when grown at e...
Inflorescence architecture of barley (Hordeum vulgare L.) is common among the Triticeae species, which bear one to three single-flowered spikelets at each rachis internode. Triple spikelet meristem is one of the unique features of barley spikes, in which three spikelets (one central and two lateral spikelets) are produced at each rachis internode. Fertility of the lateral spikelets at triple sp...
in order to determine combining ability, heritability and heterosis of some agronomic traits in rice, 4 pure lines were crossed with 2 cytoplasmic male sterile testers. parents and their f1 progenies arranged in rcb design with three replications. analysis of variance showed significant differences among genotypes for all traits, except for filled grains/panicle. furthermore, the crosses effect...
The experiment was conducted under the agro-ecological zone of Modhupur Tract (AEZ-28) to determine the genetic diversity among 39 rice genotypes, collected from Bangladesh Rice Research Institute, Lal Teer Seed Ltd. and Chittagong Hill Tracts. The genotypes were grouped into six clusters based on Mahalanobis’s D 2 statistics and Canonical Variate Analysis. Cluster I consisted with the highest ...
To evaluate the grain-filling pattern, Chinese first super hybrid rice, Liangyoupeijiu was grown under tillage and establishment methods at a spacing of 20 cm × 20 cm with one seedling hill-1 and at a seeding rate of 22.5 kg ha-1 in Changsha, Hunan Province, China in 2012. Our results showed that, superior grain weight in TP had always higher than DS up to 24 DAH but at 36 DAH, grain weight had...
Ratooning means regrowing of rice plant after harvesting of first product which is specific physiologic characteristic of rice plant. It is an effective method for increasing of efficiency of production along with less investment and also lack of necessity for increasing of the field of rice plant. Ratooning more over, affects on the optimal usage of agricultural field. In order to achieve this...
Rice (Oryza sativa L.) inflorescence (panicle) architecture is an important agronomic trait for rice breeding. A number of high-yielding japonica rice strains, characterized by an erect panicle (EP) of their architecture, have been released as commercial varieties in China. But no EP-type indica varieties are released so far. Here, we identified two allelic erect-panicle mutants in indica rice,...
A study was conducted in the field to identify the N application stages which greatly determine spikelet differentiation and degeneration of rice (Oryza sativa L.). Spikelet differentiation and degeneration were greatly influenced by time of N application. N application at the neck-node differentiation stage significantly increased spikelet differentiation and that at the active meiosis stage s...
