Abstract: Correlation and Path analysis were carried out with 38 clones selected from clonal-I ratoon population derived from a cross Co 7204 x Co Pant 97222 and 7 commercial sugarcane genotypes on different yield and its component traits. Character association analysis revealed the significant and positive association of brix yield, commercial cane sugar yield, single cane weight, number of millable canes, green top yield, cane height, girth of cane, plant height, number of inter nodes and inter nodal length with cane yield. Path coefficient analysis revealed that sucrose percent showed high positive direct effects followed by brix yield, number of millable canes, cane height, single cane weight, harvest index, green top weight, green top yield, plant height and girth of cane. It was also revealed that number of millable canes, single cane weight, green top weight, cane height, plant height, girth of cane, number of internodes, number of internodal length and commercial cane sugar yield contributed indirectly to cane yield through brix yield. These characters also exhibited highly significant positive association with grain yield as well as among themselves. Hence, simultaneous selection for brix yield, single cane weight, number of millable canes, green top yield, cane height, girth of cane and plant height commercial cane sugar yield will be more rewarding for obtaining the high yielding sugarcane clones.
