Acknowledgement

It is a matter of gratitude and euphoria to grace back and recall the path
one travels during the days of hard work and pre-perseverance and it is still great
at this juncture to recall the faces and spirit in the form of parents, teachers,
friends, near and dear ones. I would consider this work nothing more than
incomplete without attending to the task of acknowledging the overwhelming help I
received during this endeavour of mine.
Fervently and modestly, I express my deep sense of gratitude to Dr. J. P.
Upadhyay, University professor, Department of Plant Pathology, Dr. Rajendra

on the eve of completion of my thesis. This is a long adventurous journey to the
unknown destination with a hope for future.
I was not alone in this journey, to accomplish this Hercules task. Today is

who helped me a lot to cross the way, in finishing the marathon work.
