ABSTRACT
Genetic variability and interrelationships of characters in 23 genotypes of sorghum (Sorghum bicolor (L.) Moench.) were studied in four environments. Estimates of GCV and PCV were higher for stover yield, biological yield and panicle weight. High heritability was associated with high genetic advance for stover yield and biological yield which reflected that additive gene effect were important in genetic control of these characters. Grain yield was positively correlated with biological yield, stover yield and number of leaves per plant. Eighteen characters considered in this study accounted for 72.42 per cent of variation in grain yield. Path analysis revealed importance of stover yield, harvest index, number of leaves per plant and flag leaf area.
