Rice is the staple food for 2.5 billion people, growing 9% of the earth's arable land. India and Indonesia are the major countries in Asia producing the 85% of the rice produced in the world. A steady increase in production, choice of appropriate selection method is needed to further raise to genetic yield in rice. The efficiency of selection methods like pedigree, bulk and single seed descent, etc. primarily depend upon genetic variability. Although, hybridization in plant breeding provides the useful source of variability, but hybridization in combination of mutation would be expected to...

This book entitled "The Active Sun" presents an observational study of some dynamical phenomena in the solar atmosphere, their physical interpretations, and consequences. This book deals with both space-borne and ground-based observations at multiwavelength (Visible, EUV, X-ray, Radio) to address various scientific issues. The book contains the investigations of the novel observations of the multiple MHD wave harmonics (fast kink, slow-acoustic) in various types of magnetic flux-tubes in the solar atmosphere at small (X-ray bright point loops) and large (prominence, coronal hole)to diagnose...
