Abstract


To find out well tolerant genotypes of sugarcane (Saccharum officinarum L.), a trial was laid out in randomized complete block design under split plot arrangement, having three repeats with a plot size of 9.6 m × 4 m. Three irrigation coefficient viz., 1.0, 0.8 and 0.6 were kept in main plots while the 5 sugarcane clones/varieties (S2003-US-114, S2003-US-778, S2006-US-832, CPF 246 and CPF 247) were planted in sub plots. Significantly higher cane yield of 91.58 t ha-1 at 1.0 co-efficient, while the least (74.14 t ha-1) at 0.6 and an intermediate (81.48 t ha-1) at 0.8 co-efficient was recorded. Being smaller canopy with erect leaves and waxy stem, the clone S2006-US-832 excelled among other clones for cane yields of 109, 92 and 88 t ha-1 under 1.0, 0.8 and 0.6 coefficients, respectively. The clone S2003-US-778 produced minimum cane yield of 72.22, 65.97 and 60.50 t ha-1 under 1.0, 0.8 and 0.6 coefficient, respectively, while all other varieties/clones were intermediate in their expression. Irrigation regimes have no significant effect on sugar recovery.
