Abstract: Genetic variability, correlations and path coefficients were studied in sugarcane taking nineteen phenotypically diverse midlate clones along with three checks, which were planted in randomized block design. The study revealed highly significant differences among the 19 clones for all the characters studied. All the characters under study indicated the ample variation of these characters. Maximum heritability coupled with high genetic advance observed for stalk diameter (cm) and germination% (45 days) indicated the presence of additive gene action and direct selection may be highly effective. Correlation coefficient revealed that cane yield was found to be significantly and positively correlated with CCS (t/ha), number of millable canes at harvest (000/ha), number of shoots (000/ha) at 240 days, number of tillers (000/ha) at 120 days, germination % (45 days), stalk length (cm) and single cane weight (kg). Path coefficient analysis indicated the highest positive direct effect of number of millable canes at harvest (000/ha) on cane yield. The findings presented herein aimed at developing cultivars with superior performance, resilience and adaptability to meet the growing demands of the sugarcane industry in a changing agricultural landscape.
