The use of Cicer reticulatum L. for genetic improvement of cultivated chickpea
The diverse gene pool of wild chickpea (Cicer reticulatum L.) has the potential for use to improve a range of agronomically important traits in cultivated chickpea. This study was conducted to evaluate the phenotypic and genetic variations of 486 lines derived from interspecific crosses between C. …

Techniques for Seed Computation and Testability Enhancement for Logic Built-In Self Test
With the increase of device complexity and test-data volume required to guarantee adequate defect coverage, external testing is becoming increasingly difficult and expensive. Logic Built-in Self Test (LBIST) is a viable alternative test strategy as it helps reduce dependence on an elaborate …

QTL Mapping of Panicle Architecture and Yield-Related Traits Between Two U.S. Rice Cultivars 'LaGrue' and 'Lemont'
<p>Grain yield in rice consists of multiple yield components such as number of panicles/plant, number of tillers/plant, and number of seeds/panicle. Panicle architecture is an important yield trait yield as the number of seeds on a panicle greatly contributes to the overall panicle yield. A QTL …

Examining Hessian fly (Mayetiola destructor) management concepts and quantifying the physiological impact of hessian fly feeding on post-vernalization selected cultivars of winter wheat in Kansas
… (Say), has been a historically significant pest of wheat in Kansas. However, it has been 60+ years since research has been conducted examining the flies’ activity throughout the year. Results of pheromone trapping in 4 counties in Kansas shows that Hessian fly (HF) males are actively flying in …

Ecological strategies of two Ranunculus species in relation to seasonal submergence
This thesis is concerned with the role of submergence in the ecology of the perennial <i>Ranunculus repens</i> and the annual <i>R. sceleratus</i>, both of which are common in seasonally submerged habitats. Evidence is presented for genetic differentiation between <i>R. repens</i> populations with …

Pollination Limitation to Reproductive Success in the Missouri Evening Primrose, Oenothera Macrocarpa (Onagraceae)
… was investigated in three Missouri populations of Oenothera macrocarpa, a hawkmoth-pollinated, perennial herb. The populations represented extremes in size and habitat quality. Fertilization success (proportion of ovules fertilized) increased following supplementation with the mean across …

Physiological responses of common bean(Phaseolus vulgaris L.)genotypes to water stress
… likely to experience water stress. The purpose of the study was to determine the association of the morphophysiological traits with water stress and how they relate to grain yield in common beans. A field experiment involving eight common bean genotypes (CAR-ZAR, KE 3, ZM 4488, KE 4, SER 76, SER …

SELF-INCOMPATIBILITY IN CHEIRANTHUS ALLIONII
<p>The presence of a self-incompatibility (SI) system in the polyploid crucifer, Cheiranthus allionii = Siberian wallflower, was suggested by results of greenhouse screening and confirmed by results of controlled pollinations in the field. Sporophytic control of the system was indicated by a …

Understanding the importance of side information in graph matching problem
… matching algorithms rely on the availability of seed vertex pairs as side information to deanonymize users across networks. Although such algorithms work well in practice, there are other types of side information available which are potentially useful to an attacker. In this thesis, we …

A comparison of the seed dispersal service offered by chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla)
The handful of studies that have investigated chimpanzee and gorilla seed-dispersal identify these primates as important dispersal agents. These studies do not, however, make any measure of the 'quality' of the dispersal service offered by chimpanzees and gorillas. Determining 'quality' requires a …
