This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, 75 cultivars highly resistant to tan spot were identified. A positive correlation (r = 0.864; P = 0.001) was found between seedling resistance and adult plant resistance. Inheritance of tan spot resistance was found to be qualitative goverened by single major genes. Three novel resistance genes: tsn3, tsn4 and tsn5 were identified and located on chromosomes 3D, 3A and 3B, respectively. Linkage analysis using SSR markers showed that both the tsn3 (tsn3a, Tsn3b and tsn3c) and tsn4 genes are clustered in the region around Xgwm2a on the short arm of chromosome 3D and 3A, respectively.

Book excerpt: Disease resistance is one of the major factors that can be improved to sustain yield potential in cultivated crops. This book looks at disease resistance in wheat, concentrating on all the economically important diseases -- their economic impact and geographical spread, breeding for resistance, pathogen variability, resistance mechanisms and recent advances made on resistance genes. Newer strategies for identifying resistance genes and identify resistance mechanisms are discussed, including cloning, gene transfer and the use of genetically modified plants.

This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated 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 dis semination phases of the activity 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 volumes 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 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tan spot of wheat, caused by the fungus 'Pyrenophora tritici-repentis ' (Died.) Dreches., has become a major component of the leaf spot disease complex in the prairie region in recent years. On susceptible host cultivars 'P. tritici-repentis' induces two distinct symptoms, tan necrosis and extensive chlorosis. To date, five races of 'P. tritici-repentis ' have been identified based on their reaction on a set of wheat differential cultivars. The major objective of this study was to investigate the genetics of resistance to tan spot in several diverse hexaploid wheat cultivars to races 1, 2, and 3, and to the culture filtrate of 'P. tritici-repentis ', race 2. The F1 and F2 generations and F 2:3 and F2:8 families of crosses between the seven selected genotypes were tested with each race in growth room experiments. Two independently inherited genes controlled resistance to tan spot of wheat. A single dominant gene controls resistance to chlorosis induced by races 1 and 3, while a single recessive gene controlsresistance to necrosis induced by races 1 and 2. The same recessive gene controls resistance to necrosis induced by spore-inoculation or culture filtrate infiltration of 'P. tritici-repentis', race 2. This indicated that infiltration with the culture filtrate could replace spore-inoculation when testing for resistance to the necrosis component of tan spot. No segregation was observed in crosses among the resistant cultivars for both the necrosis and the chlorosis components, indicating that the resistant cultivars carried the same resistant genes. The second objective of this study was to assess the genetic similarity among different isolates of 'P. tritici-repentis' and to determine if this similarity is related to race classification or geographic origin of the isolates. Thirty-eight different isolates including other ' Pyrenophora' species were studied with 30 RAPD primers. Cluster analysis and AMOVA indicated that high genetic variability existed among the iso.
