This book was released on 2010-03-23 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of a recent spread of a new and highly virulent race of Puccinia graminis f. sp. tritici called Ug99, stem rust is becoming a serious threat to wheat production in Ethiopia and other east African countries. Therefore, there is an urgent need to analyse the virulence spectrum of Pgt populations in Ethiopia. Wheat stem rust samples were collected in 2006 and 2007 in Arsi, Bale, Shewa and the Northwest regions of Ethiopia to determine the virulence diversity and race distribution in P. graminis f. sp. tritici populations. Stem rust incidence was high in Arsi, Bale and East Shewa. In Northwest Ethiopia, and North and West Shewa, stem rust was prevalent at low levels. A total of 152 isolates was analyzed and 22 races were identified. Races TTKSR (Ug99), TTHSR and RRTTR were predominant with frequencies of 26.6, 17.7 and 11.1%, respectively. These races were also detected in all regions. It turned out that the highly virulent race designated as Ug99 was present throughout the country and dominated in all regions except Northwest Ethiopia. A variant of Ug99, which is virulent against Sr24 was not detected in this study. Four stem rust resistance genes (Sr13, Sr30, Sr36 and SrTmp) were found to confer resistance to most of the races prevalent in Ethiopia. With the exception of Sr30, which is not effective to Ug99, the other three genes can be used in breeding for resistance to stem rust in Ethiopia.

Available in PDF, EPUB and Kindle. Book excerpt: Presents "criticisms and defenses which were made in Parliament when statutes delegating legislative authority were being considered. Have the members of Parliament been jealous of their legislative power or have they consented, without serious objection, to successive abdications demanded by successive Governments? When Governments have urged delegations to the executive what grounds have they set forth to justify their proposals? What suggestions have been voiced in Parliament to the end that further delegations will be less necessary or that, if made, executive action will be more effectively scrutinized? The present monograph attempts to answer such questions." -- Preface, page 5.
