Correlation and Path Coefficient Analysis of Component Characters on Juice Yield in Sweet Sorghum Genotypes (Sorghum bicolor (L.) Moench)

The present experimentation was conducted to assess correlation and direct indirect relation between juice yield and its contributing traits in 33 sweet sorghum genotypes at Sorghum Research Station, VNMKV, Parbhani during kharif 2019. Analysis revealed that juice yield exhibited highest significant and positive correlations with Millable cane weight (G=0.9018, P=0.8938) at genotypic and phenotypic levels followed by total fresh biomass, juice extraction percentage, Stem girth, plant height, Days to maturity and internodal length. Grain yield per plant exhibited negative but non-significant association with juice yield. Millable cane weight, juice extraction percentage and days to 50 per cent flowering showed highest positive direct effect on juice yield. While days to maturity, plant height and grain yield per plant had negative direct effect on juice yield per plant. Millable cane weight showed maximum indirect effect via total fresh biomass, juice extraction percentage and plant height. Considering both correlation and path coefficient, it can be concluded that the traits stem girth, internode length and high total fresh biomass, millable cane weight and juice extraction percentage should give importance for increasing the juice yield in sweet sorghum genotypes.
