Sorghum [Sorghum bicolor (L.) Moench] is the fi fth important cereal crop in the world after wheat, rice, maize and barley. Of late, it has emerged as ‘fuel’ crop in addition to its food, feed and fodder utilities. Sorghum is predominantly a selfpollinated crop and development of new ‘varieties’ is a natural option for crop improvement. However, there is 5 to 15% outcrossing in sorghum depending upon the wind direction, nature of genotype, and humidity (House 1985), which makes it amenable for use in population improvement and hybrid development to exploit the heterosis. Discovery of genetic male sterility (GMS) and cytoplasmic-nuclear male sterility (CMS) facilitated the application of recurrent selection procedures and hybrid cultivar development methods, respectively, in sorghum improvement. In this article, male-sterile line development using CMS in sorghum is described.
