This book is prepared on the basis of some genetical, breeding, tissue culture aspects of an important oil yielding crop Groundnut. These different aspects are done by both field and laboratory experiments. The potential of a crop to respond favorably to breeding programme depends upon the nature and magnitude of variability. Groundnut production can be increased through breeding research following development of high yielding drought tolerant genotypes, selection of superior genotypes, and creating genetic variability in the most adaptive cultivars. Correlation studies provide ...
