This paper focuses on the potential of sweet sorghum (Sorghum bicolor) as an alternate raw material for bio-ethanol and bio-energy production, highlighting its advantages (in terms of cost of cultivation, cost of ethanol production, and ethanol productivity) over sugarcane molasses. Prospects of enhancing the genetic potential of sweet sorghum through various plant breeding strategies are discussed.

Forty-two sorghum lines, selected from 100 breeding lines evaluated for biomass production under salinity stress (electrical conductivity of ECe of 23.4 dS/m) in a pot experiment, were evaluated for yield and yield components under saline (ECe of 8.0 dS/m) conditions in Gangavathi, Karnataka, and under normal (non-saline) conditions in Patancheru, Andhra Pradesh, India, during the rainy season of 2004.
The sorghum lines ICSV 735, ICSV 758 and ICSV 804 have been released as Yezin 6, Yezin 7 and Yezin 5, respectively, in Myanmar. These cultivars combine resistance to S. sorghicola with yield potential almost similar to that of the commercial cultivar Yezin 1 or Yezin 3. ICSV 735 was derived from (ICSV 197 x ICSV 1)-9-1-1-2-6, whereas ICSV 758 was developed from (ICSV 197 x A 13108)-1-2-1-1-1. ICSV 804 was obtained from (ICSV 197 x ICSV 1)-3-1-1-1-1.
ICSV 88032, a high-yielding sorghum line highly resistant to S. sorghicola, was developed in India by pedigree breeding from a cross between ICSV 197 (midge-resistant line) and ICSV 1 (a high-yielding sorghum cultivar). In the international sorghum variety and hybrid adaptation trial, ICSV 88032 recorded yields of 4.8-5.2 t/ha during 1990-91, compared to 5.0-5.3 t/ha for ICSV 112, a released commercial cultivar, at Bhavanisagar (Tamil Nadu) and Patancheru (Andhra Pradesh).
