Weighted selection on coarse-grain hypercubes

Proceedings.Seventh IEEE Symposium on Parallel and Distributed Processing, 2002
Given n weighted records distributed evenly among a p-processor hypercube, p/spl les/n, we present efficient parallel algorithms for solving the weighted selection and related problems in the coarse-grain weak-hypercube model. A special case of the weighted selection problem, in which all the weights are equal, is known as the (unweighted) selection or

The TaGW2-TaSPL14 module regulates the trade-off between tiller number and grain weight in wheat.

Journal of Integrative Plant Biology
IDEAL PLANT ARCHITECTURE1 (IPA1) is a pivotal gene controlling plant architecture and grain yield. However, little is known about the effects of Triticum aestivum SQUAMOSA PROMOTER-BINDING-LIKE 14 (TaSPL14), an IPA1 ortholog in wheat, on balancing yield ...

gw2.1, a new allele of GW2, improves grain weight and grain yield in rice

Plant Science, 2022
Grain weight is an important characteristic of grain shape and a key contributing factor to the grain yield in rice. Here, we report that gw2.1, a new allele of the Grain Width and Weight 2 (GW2) gene, regulates grain size and grain weight. A single nucleotide substitution in the coding sequence (CDS) of gw2.1 resulted in the change of glutamate to ...

Rice Grain Morphological Characteristics Correlate with Grain Weight and Milling Quality

Cereal Chemistry, 2013
ABSTRACTUsing image analysis technology, the morphological measurements of paddy, brown (BR), and milled (MR) grains of 408 rice (Oryza sativa L.) lines representing a wide range of grain morphology were obtained, and the measurements' relationships with grain weight, milling quality, and chalkiness were investigated.

Genetic effects determining rice grain weight and grain density

Euphytica, 1992
Increasing grain weight is one means of increasing rice (Oryza sativa L.) grain yields. Selection for increased density of filled grains may offer an approach to increasing rice grain weight. Before rice breeding programs can begin effectively selecting for higher grain density, the nature and amount of the genetic variation present must be evaluated ...

Factors controlling grain weight in wheat

Nature, 1977
THE physiological factors controlling differences in grain weight between cultivars of wheat are not fully resolved. The experiments described here indicate that final grain weight in two cultivars of wheat is mainly dependent on the rate of accumulation of dry matter, which in turn is governed by the number of endosperm cells formed.

Practicable Group Testing Method to Evaluate Weight/Weight GMO Content in Maize Grains

Journal of Agricultural and Food Chemistry, 2011
Because of the increasing use of maize hybrids with genetically modified (GM) stacked events, the established and commonly used bulk sample methods for PCR quantification of GM maize in non-GM maize are prone to overestimate the GM organism (GMO) content, compared to the actual weight/weight percentage of GM maize in the grain sample. As an alternative

Grain Weight in Cultivated Strains of Paddy

Madras Agricultural Journal, 1968
Yield in rice being a complex character is influenced very much by certain contributory factors and these yield components individually and in combination affect the yield. Enumerating the selective factors of the yielding ability in cereals, Panse and Khargonkar (1949) included grain weight as one of the important indices among others Simolete (1947 ...

Hygroscopic weight gain of pollen grains from Juniperus species

International Journal of Biometeorology, 2014
Juniperus pollen is highly allergenic and is produced in large quantities across Texas, Oklahoma, and New Mexico. The pollen negatively affects human populations adjacent to the trees, and since it can be transported hundreds of kilometers by the wind, it also affects people who are far from the source.

Interrelationships between Panicle Weight, Grain Yield, and Grain Yield Components in Oat

Crop Science, 1991
The value of panicle weight as a selection criterion for improving grain yield in oat (Avena sativa L.) is largely unknown. Panicle weight in oat combines two of the three primary yield components, spikelets per panicle and seed weight, into a single trait that is easy to measure. Three oat populations were evaluated in 1987 through 1989 for the effect
