Correlation and path coefficient analysis in sorghum [Sorghum bicolor (L.) Monech] for ethanol yield

Abstract

In order to understand the association of ethanol and its attributing traits, 110 diverse genotypes of sorghum were studied for Character association and Path coefficient analysis. Based on the correlations for characters studied revealed that brix percent, total soluble sugars, juice yield has significant positive correlation with ethanol yield while negative association with grain yield, plant height, days to 50% flowering and days to maturity. In path analysis study it can be concluded that juice yield, total soluble sugars content, brix%, Fresh stalk yield and 1000 grain weight play an important role in selection criteria for improving the character ethanol content.
