This book is aim at molecular mapping and identification of QTLs for stay green and other related traits in sorghum. Stay-green makes plant resist to premature senescence, retain green leaf area, fill grain normally, and resist lodging under conditions of post- flowering drought stress. Molecular mapping of these traits help for markers assisted selection in developing improved varieties within short period of time. The author attempted to map and investigate chromosomal region harboring gene for drought tolerance traits in sorghum. The first part of the book provides conceptual ...
