Estimates of genetic variability resulting from single, top, and double cross populations in durum wheat (Triticum turgidum L. var. durum)

Creator:: Abdennadher, Mourad
Abstract:: The success of a plant breeding program depends upon the availability of useable genetic diversity. Such diversity may be enhanced depending on the type of hybridization strategy employed. Segregating progenies resulting from F2 populations, a double cross, and a top cross were compared for the amount of useable genetic diversity...

Factors affecting semen quality and their effects on the fertilizing ability of broiler breeder spermatozoa using a fluorometric assay

Creator:: Bootwalla, Salim Mohsin
Abstract:: Three distinct studies using an ethidium bromidedigitonin fluorometric assay were conducted to determine if the fertilizing ability of individually caged broiler breeder males (BBM) could be enchanced by nutrition, breeding and semen extender viscosity. The first study evaluated the effects on the spermatozoal quality of BBM by feeding corn-soybean meal...

Effect of ethanol and low dietary copper on perinatal and postweanling copper utilization in the rat

Creator:: Baek, Jong Ho
Abstract:: The hypotheses of this research were (1) to test if the antagonistic effect of ethanol on liver copper could be seen within a short period when ethanol ingestion, low dietary copper and high metabolic demand represented by either pregnancy plus lactation or rapid growth are simultaneously present and (2) to...

Evaluation of combining ability in mosquitofish

Creator:: Pongthana, Nuanmanee
Abstract:: Two replications of a half dial lei cross experiment were performed among four inbred lines of mosquitofish, Gambusia affinis. These inbred lines originated from three random-bred stocks: OR, TX and CD. The experiment was conducted as a completely randomized design. Experimental material consisted of parental lines and F₁ populations maintained...

Effect of callipyge gene on lamb growth, carcass characteristics, and meat quality

Creator:: Srinivasan, Haribaskar
Abstract:: Callipyge (CLPG, n=16) and normal (N, n=11) lambs were produced from Polypay dams and Dorset sires heterozygous for the CLPG gene to study the effects of the gene on growth and carcass and meat quality parameters. CLPG lambs had higher average daily gain than N lambs (0.26 vs 0.23 kg/day,...

Influence of leaf types on canopy architecture and grain yield in selected crosses of spring wheat Triticum aestivum L.

Creator:: Vanavichit, Apichart
Abstract:: The effects of erect leaf canopies on enhancing grain yield in wheat is not understood. The main objective of this study was to understand the effect of leaf angle on grain yield by comparing randomly derived-lines from crosses of erect and droopy leaf spring wheats. Nine traits associated with canopy...

Duration and rate of grain filling and subsequent grain protein content in selected winter wheat populations

Creator:: Mou, Beiquan
Abstract:: The lack of information regarding the inheritance of the duration and rate of grain filling, and the possible relationship between grain fill and grain protein content in wheat prompted this study. Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late maturing cultivars adapted to Oregon, 'Stephens' and...
