A filed experiment was conducted to study the association analysis of grain yield with its attributes and growth components in winter sorghum under dryland conditions in Vertisols during rabi season of 2002-03 at Research Farm of Central Soil and, Water Conservation Research and Training Institute, Research Centre, Be.llary, Karnataka State, India. Among the varieties evaluated, RSLG 262 (Mouli) recorded greater grain (2041 kg ha-1) and straw yield (3.11 t ha-1), followed by SPV 1591 (1919 kg ha"1) and SPV 1546 (1832 kg ha"'). Greater harvest index (42.8 and 39.6) and dry matter efficiency (0.471 and 0.366) was observed in SPV 1537 and Mouli varieties, respectively. Grain yield of winter sorghum w^as positively correlated with growth components 7. e... dry matter production and its distribution in leaf, stem and ear at harvest. Positive correlation was observed between grain yield and straw yield and yield components i.e., panicle length, panicle diameter, grain mass per plant and 1000-grain mass. Grain yield and water use efficiency (WUE) was significantly and positively correlated (0.992)
