Significantly highest cane yield (120.04 MT/ha) was noticed with Co 87025 followed by Co 88071. Significantly lowest cane yield of 80.85 MT/ha was noticed with Co 89010.

5. Quality parameters

Among the quality parameters, Brix(%) and Reducing sugars(%) shown non-significant difference. However Co 89010 recorded significantly higher pol(%) of 18.74 compared to other varieties except Co 88028 and CoM 88121 which were on par with each other.

6. Commerical cane sugar yield (MT/ha)

Varieties did not differ significantly. However highest CCS yield (13.04 MT/ha) was noticed in Co 87025 followed by Co 88028 and CoM 88121.
