Abstract

Sorghum yield and production stabillity are constrained by various biotic stresses such as different insects and diseaes. The biotic stresses not only reduce the yield but results in poor grain quality thus hampering its marketability and utiilization leading to severe economic losses. Development of host plant resistance is one of the cheapest and sustainable methodss for managing the insect pests and diseases. Improvement in stress resistance will increase ecological fitness, reduce pesticide use, and facilitate creation of a sustainable production system with increased efficiency, profitability and to enhance grain quality/end use traits. An integrated synergistic system involving plant breeding and genomics research using advanced molecular tools could increase the efficiency and precision of crop improvement. This chapter deals with recent development with regard to sorghum adaptation to different production systems, major biotic stresses affecting sorghum production, understanding genetic control of biotic stress resistance, screening techniques developed, QTLs identified for various stresses and the program made in cultivar development using this knowledge.
