ABSTRACT
Correlation and path coefficient analyses were studied in fifty two diverse genotypes of sweet sorghum in order to understand the interrelationship of sugar yield and its attributing quantitative traits. From this study sucrose yield showed highly significant positive phenotypic (P) and genotypic (G) correlation with stem girth, millable cane weight, sucrose percentage, juice extraction percentage, cane yield, juice yield and significant correlation to days to physiological maturity. The results of path analysis of component characters of sucrose yield indicated maximum positive direct effect of cane yield followed by sucrose percent, juice yield, days to physiological maturity and juice extraction percentage. Further, the other traits also exhibited high positive indirect effect via juice yield resulted in their positive correlation with sucrose yield.
Key words :
Correlation, path analysis, sorghum bicolor, sucrose yield, sweet sorghum.
