Not AvailableTo physiologically categorize drought tolerance characteristics of post-rainy sorghum [Sorghum bicolor (L.) Moench], 21 sorghum genotypes were evaluated under well watered and water deficit stress conditions for 2 years. Water deficit stress showed mixed effect among the genotypes for days to flowering, while other traits were adversely affected. Over 35 % reduction in grain yield was recorded due to post-flowering drought. Retention of green leaf area (GLA) during grain filling stage was found to be associated with drought tolerance. Loss of GLA started earlier and faster among high susceptible lines compared to tolerant lines. Based on stability analysis and drought susceptibility indices IS 23514 and Phule Chitra were identified as stable drought tolerant lines. Identified lines can be used in post-rainy sorghum breeding and molecular studies in future. The study also suggests that easily scorable physiological traits such as retention of green leaf area can be combined with stability analysis and DSI to identify drought tolerant genotypes.Not Availabl
