experimental trials and in preparation of this manuscript.
I avail this opportunity to express my gratitude and sincere thanks to
Dr. K.Raja Reddy, Dean P.G studies, A.N.G.R.A.U for permitting me to carry
out my research work at A.R.S, Perumallapalle and Dr. N.V.Naidu, Associate
Dean, S.V.Ag College, Tirupati who gave me optimum work load and more
time to complete this dissertation.
I am happy to gratify the help rendered by Dr. D. Mohan Reddy,
Associate Professor, Department of Genetics and Plant Breeding,
S.V.Agricultural College, Tirupati, for his kindfull support and insightful
suggestions. My heartfelt thanks are due to Dr.M.Reddisekhar, Professor and
