Abstract
Correlation studies under terminal drought conditions indicated that, grain yield per plant was highly correlated with panicle harvest index, drought response index and harvest index; whereas under irrigated conditions it was highly correlated with ear head weight per plant and test weight. Drought response index was correlated to grain yield per plant under drought environments only Under both conditions, number of productive tillers per plant exhibited positive significant association with maximum number of characters and ear head girth showed negative significant association with maximum number of characters. Drought responsive traits had mutual association with each other under terminal drought condition, but not under irrigated conditions. Hence, while selecting drought responsive genotype, emphasis should be given to drought stress responsive traits viz., root length per plant, proline content and drought response index. Thus, correlation results reveal that alleles controlling the grain yield in stress and non-stress environments are partially different; this underlines the need to select in target environments to improve the performance of genotypes
