Abstract: Twenty two accessions of sugarcane were investigated for determining genetic variability and suitable combination of characters for maximizing cane yield and sucrose percentage based on twelve pivotal quantitative traits using correlation and principal component analysis. The analysis of variance revealed considerable range of variability for all the characters studied. Cane weight was positive and significantly correlated with plant height, cane height, leaf area, brix value, juice contents and bagasse weight. Bagasse weight, dry matter contents and brix value had positive significant correlation with sucrose percentage. Principal component analysis was applied and three components which caused more than 70 percent of total variance were considered important and all the traits were studied in accordance to these components. Results indicate that different sugarcane accessions can be exploited for yield contributing traits and for specific use high yielding can be developed.
