Varieties of Canesugar
1. Co 89003
- Co 89003 is a high sugared high yielding early maturing clone, selected from the progeny of the cross Co 7314 x Co 775 at Sugarcane Breeding Institute, Coimbatore and tested at Sugarcane Breeding Institute, Regional Centre, Karnal
- Due to high sugar and high yield, Co 89003 was recommended for commercial cultivation in Punjab in 1997 and Haryana in 2001
- Co 89003 has medium thick greenish yellow canes. Sheath splitting is common. Bud groove is prominent and is extended to 3/4th or even entire length of internodes. The clone is free from spines, splits and pith.
- Co 89003 has about 11% fibre. The jaggery is the golden yellow colour of A1 grade.
- It is a soft cane and hence also suitable for chewing.
- Co 89003 showed 31% and 42% improvement of cane yield over CoJ 64 during autumn and spring, respectively. The improvement for sucrose% over CoJ 64 was 3.56% during autumn and 5.56% during the spring season.
- Co 89003 gives good ratoon.
- Co 89003 is moderately resistant to the prevalent races of red rot pathogen. However, it is susceptible to wilt disease. The Wilt infection in Co 89003 is associated with root borer and termite infestations. Therefore, the disease can be minimised by applying Chlorpyriphos @ 2 litres/acre at the time of planting / ratooning as well as during August.
