Use of RAPD markers in plant varietal development
… markers have played an important role in plant varietal development. With the discovery of polymerase chain reaction (PCR), very low or single copy sequences can act as molecular markers because during the PCR, DNA is multiplied to such an extent that it can be easily visualized on an agarose …

Using NMR spectroscopy and linear discriminant analysis to molecular profile varietal honey
<p>In recent years, varietal honey has been a massive target of adulteration through mislabeling and the addition of other sugars. Unethical companies do this to cut production costs while still charging the consumer full price. Previous studies have used nuclear magnetic resonance (NMR) to unravel …

Broccoli yield response to cabbage looper and varietal preferences of lepidopterous pests of broccoli
Respondents of the 1986 Broccoli Growers Survey grew an average of 6.2 acres of broccoli in Fall 1986; popular varieties were Green Valiant (87.5% of respondents), Packman and Emperor (62.5%). Less than 5% of tobacco land was converted to broccoli production by 62.5% of the growers. Before heading, …

Physiological and agronomic aspects of rice varietal responses to low and high nitrogen management
Modern rice (Oryza sativa L.) varieties produce very high yields under high input and favorable environments. Limited work has been done to develop plant types suitable for less than optimal environments at moderate N management levels. The objectives of this study were: 1) to examine the …

An assessment of varietal improvement and extension services in cotton production in Magoye District, Zambia
… The study was conducted to assess the impact of varietals development and extension services in cotton production. The specific objectives were to determine whether farmers are influenced by cotton seed companies in terms of what varieties to use, to determine the level of farmer knowledge about …

Eliciting farmer preferences for rice varietal trait improvements using an experimental methodology based on investment games
… this thesis analyses farmer preferences for rice varietal trait improvements (VTIs). A total of 122 rice-farming households participated in the experiment, with both the husband and wife taking part in activities. The thesis consists of three core chapters, which specifically analyse the …

Drivers of Sauvignon blanc aroma at harvest: C6 compounds, antioxidants, and sulfur
Important volatile varietal thiol compounds contribute significantly to the aroma of Sauvignon blanc wines. They impart pleasant tropical, passion fruit, gooseberry, and grape fruit notes to wine, among other aromas. The formation of these compounds has been the subject of much research, mainly …

Inter-varietal variation in elemental uptake by rice and its implications for public health : a case study of Dareta village, Zamfara State, Nigeria
… rice varieties accumulate Pb and whether varietalselection could be used to reduce dietary Pb exposure.Whilst the Pb poisoning is having a truly devastating consequence, the dietary transfer of othercontaminants in Nigeria also needs to be understood. One group of contaminants that have …

The role of genotypic diversity in stabilizing plant productivity in variable environments
Crop varietal mixtures have the potential to increase yield stability compared to monocultures in highly variable and unpredictable environments, yet knowledge of the specific mechanisms underlying enhanced yield stability has been limited. Field studies are constrained by environmental conditions …

Identification of Pythium species inducing common bean (Phaseolus vulgaris L.) root rot symptoms and development of backcrosses to improve the level of varietal resistance to this disease
… problem. This work was undertaken to improve the varietal resistance of common bean to limit the damages caused by Pythium in Rwanda. An analysis of the diversity of Pythium species associated with root rot was conducted through collect of samples of common bean plants throughout the country and …

Extractability and viscosity of β-glucan from oat bread during in vitro digestion
… conditions and to see whether there were varietal differences. Oat flours of twenty different cultivars were used to bake breads which were subjected to in vitro digestion. The resulting extracts were studied for viscosity using a rheometer, and the β-glucan contents of the breads and the …
