I would like to express my deepest gratitude to my major advisor professor Mengistu Ketema, and my co-advisor Mr. Beyan Ahmed, whose contribution is immense, and without their involvements, the accomplishment of this research would have been difficult. Besides, their kind and gentle guidance and advisor-ship from the early design of the research proposal to the final write-up of the thesis by adding valuable, constructive and ever-teaching comments highly improved the contents of the thesis. Thirdly, my heartfelt thanks go to the Ethiopian Institute of Agricultural Research for giving me the chance to join the MSc program. Besides, I would like to thank National Agricultural Biotechnology Research Center and Holeta Agricultural Research Center’s staff members, more particularly Mr. Obsi Desalegn, Dr. G/rufael Girmay, Mr. Adisu Getahun, Mr. Takele Mebratu, Mrs. Yewubdar Tadese and Mr. Shumet Embiale Fourthly, it is my pleasure to appreciate African Economic Research Consortium (AERC) for their financial support to accomplish my MSc study at Haramaya University and University of Pretoria.
