The present book entitled 'Genetic variability and character association in sorghum' provide information to determine various parameters of genetic variability and nature of inter relationships among sorghum germplasm accessions affecting grain yield with following objectives. 1. To estimate the variability parameters for yield and yield contributing characters. 2. To work out heritability and genetic advance for different traits. 3. To study the extent of association (correlation) existing among different yield components with grain yield. 4. To study the direct and indirect contributions (path analysis) of each component character towards yield.
