RANGE-WIDE PHENOTYPIC AND GENETIC DIFFERENTIATION IN WILD SUNFLOWER

– Fixed costs remain the same for different levels of production – Variable costs are the costs of variable inputs (such as raw
materials and labor) and vary directly with output
– Marginal cost is the cost of the last unit of production – Total cost is the sum of all producti[r]

™ The highest yield and oil content were achieved with a nitrogen rate of 80 kg/ha. This N rate would also provide the greatest profits for farmers.

Genetic variability, genotypic and phenotypic coefficients of variation, heritability and genetic advance for twenty-one characters in twenty-eight parental lines of hybrid rice were studied. The analysis of variance revealed highly significant differences for all the characters among the genotypes.[r]

Ginsenoside Rb1 also suppressed food intake and body weight gain in obese rats, while
improving glucose homeostasis. Modulation of associated signaling pathways and neuropeptides in the hypothalamus was observed (Xiong et al., 2010). Further studies with mice treated w[r]

Numerous rye accessions are stored in ex situ genebanks worldwide. Little is known about the extent of genetic diversity contained in any of them and its relation to contemporary varieties, since to date rye genetic diversity studies had a very limited scope, analyzing few loci and/ or few accession[r]

What happens in the first few minutes of SAM formation should have a significant influence on the composition of the final mixed SAM if kinetic control dominates. One can postulate several possibilities in the early stages of SAM formation [146]. First, equilibration proceeds thro[r]

The genetic structure and differentiation of wild emmer wheat suggests that genetic diversity is eco-geographically structured. However, very little is known about the structure and extent of the heritable epigenetic variation and its influence on local adaptation in natural populations.

The concept of heritability is important to determining whether phenotypic differences observed among various individuals are due to genetic changes or due to the effects of environmental factors. Heritability indicates the possibility and extent on which improvement can be brought about through sel[r]

Plants and animals are responsible for a variety of useful medications. In fact, about forty percent of all prescriptions written today are composed from the natural compounds of different species. These species not only save lives, but they contribute to a prospering ph[r]

Phenotypic classification is problematic because small samples are ubiquitous; and, for these, use of prior knowledge is critical. If knowledge concerning the feature-label distribution – for instance, genetic pathways – is available, then it can be used in learning.

The present study was carried out to know the sap transmission nature of sunflower necrosis virus and detection by serological and molecular means. The disease was successfully transmitted through mechanical sap using 0.05 M potassium phosphate buffer. A maximum transmission of 52.33 per cent on cul[r]

The aim of the present study was to determine the phenotypic resistance pattern to βlactam antibiotics among Escherichia coli clinical isolates and to identify the genetic determinants responsible for β-lactam antibiotic resistance. Forty Escherichia coli isolates were included in this study. Identi[r]

The pollen tube growth in wide crosses involving Arachis hypogeae (var VRI 2, TMV 7 and TMV 13) and wild Arachis sp. (Arachis stenosperma, Arachis cruziana and Arachis kempmercadoi) have been interpreted among nine crosses. The wide crosses were monitored for pollen attrition and pollen proliferatio[r]

Fifteen genotypes of finger millet were evaluated in a field study to assess the magnitude of genetic variability, heritability and genetic advance for yield and yield contributing traits. The analysis of variance revealed that there were significant differences among the entries for all the traits[r]

Genetic variability and heritability of quantitative traits, particularly of yield contributing traits, are of great importance in understanding phenotypic variation and the heritable portion of the variation when making selection choices.

Phenome-wide association studies (PheWAS) are a high-throughput approach to evaluate comprehensive associations between genetic variants and a wide range of phenotypic measures. PheWAS has varying sample sizes for quantitative traits, and variable numbers of cases and controls for binary traits acro[r]

The main bottleneck to elevate jatropha (Jatropha curcas L.) from a wild species to a profitable biodiesel crop is the low genetic and phenotypic variation found in different regions of the world, hampering efficient plant breeding for productivity traits.
