MARY OBODAI (CO-SUPERVISOR) DATE........................................... i DEDICATION This thesis is dedicated first and foremost to the Lord Almighty God. I also dedicate it to my dear parents Mr. and Mrs Brenya Wiafe-Akenten as well as my mother Mrs. Beatrice Akua Korantemaa and my grandmother Madam Abena Serwaa. I dedicate this work to my late grandparents the late Mr. Kofi Adarkwa and late Mrs. Afia Owusua Adarkwa of blessed memory for their support and motivating me to pursue education in early life. Finally, to all my siblings Awo Asantewaa, Nana Adwoa, Ohemaa Akua, friends (especially Miss. Millicent Amponsah), dear ones who contributed in diverse ways to the success of this thesis deserve mention. I wish the surviving ones God’s favour and blessings. ii ACKNOWLEDGEMENT I am eternally indebted to my LORD GOD ALMIGHTY for His protection, wisdom, grace and strength which enabled me to complete this research work. I am also profoundly grateful to my supervisors Prof. G.T. Odamtten and Dr. Mary Obodai who suggested the problem and guided me with patience and unstinted advice in the execution of the project and in the write up of the thesis. I wish to also thank Prof. I. K. Asante, Dr. Ebenezer Owusu and all the lecturers in the Department of Botany, for their encouragement and support in diverse ways. I am grateful to Dr. John Manful (Africa Rice Centre) and Dr. Paa Nii Johnson (CSIR Head Office) for their support in seeking sponsorship for the entire research. This assignment could not have been successfully completed without the voluntary technical assistance of Mr. Richard Takli, Miss. Juanita Prempeh, Godson Agbeley, Mr. Moses Mensah, Mr. Akangina Ababese all of the Food Research Institute, Mycology Unit Council for Scientific and Industrial Research, Ghana, Mr. Kofi Baako, Mr. George Akwetey of the Department of Botany, Miss Roberta Koku College of Agriculture & Consumer Sciences, University of Ghana for their technical assistance and also Mr. Benedict Quagraine, Mr. John Kupagme, Mr. Kwabena Acheampong. To all of them I express my sincere appreciation and wish them God’s blessings. Finally, I acknowledge with deep appreciation the major financial support of the Africa Rice Centre, based at Benin and an affiliate of Consultative Group of International Agricultural Research (CGIAR) as well as the Government of Ghana for partial financial support for the project. iii TABLE OF CONTENTS DECLARATION .................................................................................................................................. i DEDICATION ..................................................................................................................................... ii ACKNOWLEDGEMENT ................................................................................................................. iii LIST OF TABLES ............................................................................................................................ vii LIST OF FIGURES ......................................................................................................................... xiv LIST OF PLATES ......................................................................................................................... xviii LIST OF MAPS ................................................................................................................................. xx LIST OF APPENDICES.................................................................................................................. xxi ABSTRACT ..................................................................................................................................... xxii CHAPTER ONE ................................................................................................................................. 1 INTRODUCTION AND LITERATURE REVIEW .................................................................... 1 OBJECTIVES ............................................................................................................................... 37 CHAPTER TWO .............................................................................................................................. 39 MATERIALS AND METHODS ................................................................................................. 39 CHAPTER THREE .......................................................................................................................... 74 EXPERIMENTAL PROCEDURE .............................................................................................. 74 EXPERIMENT A.
