Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.
Download or read book Dwarfing Genes in Spring Wheat written by Amber Marie Robbins and published by . This book was released on 2009 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rht-B1b and Rht-D1b (formerly Rht1 and Rht2) dwarfing genes have been used extensively since the Green Revolution to reduce height and increase yield in hexaploid wheat (Triticum aestivum L.). They have been used in the development of hundreds of modern cultivars. Semi-dwarf wheat varieties containing these GA-insensitive dwarfing genes generally yield more grain than their tall Rht-B1a and Rht-D1a (formerly rht1 and rht2) counterparts. However, Rht-B1b and Rht-D1b are better adapted to high-input environments and can reduce plant performance under adverse conditions such as heat or drought stress. In such environments, Rht8, a GA-sensitive dwarfing gene, could prove beneficial. This study aimed to assess agronomic performance of Rht8 compared to Rht-B1b and Rht-D1b using near-isogenic lines of the six possible genotypes (Rht-B1b, Rht-B1a, Rht-D1b, Rht-D1a, Rht8, and rht8) in four different spring wheat backgrounds. Field trials were conducted during the 2008 and 2009 growing seasons in Bozeman and Kalispell, MT. Traits measured included plant height, coleoptile length, stem solidness, days to heading, yield, flag leaf characteristics, harvest index, and others. Measurements were taken from field trials except coleoptile length, which was grown in a temperature and light controlled growth chamber. Rht genotype had a significant effect on plant height, coleoptile length, and yield. Height reductions of 20.5%, 22.4%, and 10.1% were observed for Rht-B1b, Rht-D1b, and Rht8, respectively. Rht8 showed no significant effect on coleoptile length, while Rht-B1b and Rht-D1b exhibited reductions in coleoptile length of 21.3% and 22.8%. Rht-B1b and Rht-D1b both showed a 6.1% and 14.1%. increase in yield potential. In contrast, Rht8 showed a yield decrease of 5.3%. Of most interest to plant breeders are those traits that effect yield. Yield is a complex, multi-genic trait that is affected by many plant characteristics and environmental factors. Because of the quantitative nature of yield, it is impacted by not only the presence of dwarfing genes, but also genetic background and environmental variables. This study suggests that Rht-B1b and Rht-D1b are superior, in terms of yield potential, to Rht8. However, additional evaluation of Rht8 in differing environments is needed to elucidate its precise effects on yield and other agronomic traits.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Breeding Reviews is an ongoing series presenting state-of-the art review articles on research in plant genetics, especially the breeding of commercially important crops. Articles perform the valuable function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.
Download or read book PLANT BREEDING METHODS written by MAHABAL RAM and published by PHI Learning Pvt. Ltd.. This book was released on 2014-10-01 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive book provides a detailed account of the plant breeding methodology, covering particularly pre- and post-Green Revolution era. It elaborates on plant breeding and gene manipulation, utilization of self-incompatibility in developing hybrids, different plant breeding methods for development of crop varieties and hybrids in self- and cross-pollinated crops, nature of gene action and genotype–environment interaction. The text discusses gene manipulation in the crop plant and transfer of genes from wild species to cultivated crops, application of biotechnology in plant breeding, and genetic engineering and transgenic molecular markers as breeding tools and their limitations. It concludes with a discussion on physiologic breeding approach and new plant ideotype concepts which are new and emerging areas of interest in plant breeding research. The book will be of immense use to undergraduate and postgraduate students of Agricultural Sciences and Botany for their course study. Besides, research scholars and professionals will also find the book as an excellent source of reference.
