Co 0118 (Karan 2)

Varietal Features

Co 0118 is a selection from the progeny of the cross Co 8347 x Co 86011. This clone was identified from seedling ratoon nursery raised at Sugarcane Breeding Institute, Regional Centre, Karnal and was tested under the Pre Zonal Varietals Trial as K96‐059. It was selected as an early clone as it had pol % juice higher than CoJ 64 during November, January and March. The cane yield and sugar yield of Co 0118 was higher than that of CoJ 64.

Salient characteristics

Co 0118 is a medium thick, green‐yellow canes with obconoidal internodes, rectangular buds, lanceolate auricle on both sides (generally long on one side), shallow bud groove and weak spines on leaf sheath. The clone is free from splits, pith and bud cushion. The fibre % is about 12.78 %. The jaggery is of A1 quality with light yellow colour. This clone is moderately resistant (MR) to the prevalent races of red rot pathogen by plug method of inoculation.

Performance of Co 0118 in North Western Zone

This clone has been evaluated under All India Co‐ordinated Research Project in the North Western Zone. Co 0118 ranked 3rd in the zone for cane yield (78.20 t/ha), sugar yield (9.88 t/ha) and sucrose in juice (18.45%) based on average of 2 plant and 1 ratoon crops at 7 research stations in the zone.

Recommendation

Co 0118 was released by the Central Sub‐Committee on Crop Standards, Notification and Release of Varieties for Agricultural Crops in 2009. This variety would prove as high quality early maturing clones under assured irrigation, water stress or water logging areas. This variety is a suitable substitute for CoJ 64.

Package and practices

Among the released varieties, Co 0118 is the best alternative available of Co 0238. To avoid the dependency on single variety (Co 0238), the best option available is Co 0118. In order to avoid total failure of sugarcane crop (in case of breakdown of red rot disease) each factory / farmer may have 2 to 3 varieties. There is no doubt that yield of Co 0118 is lower than Co 0238. Even then factories / farmers should try for 2nd and/or 3rd alternate variety(s). First the cane development staffs need to convince themselves about the above facts. Then only cane development staffs will be able to convince the farmers. Following special package and practices are suggested to minimize the yield gap between Co 0118 and Co 0238.

  • My experience with Co 0118 indicates that germination is not a problem at all. In comparison with Co 0238, germination in Co 0118 is higher as well as quick.
  • Co 0118 is having longer internodes than Co 0238. Ensure that correct quantity of seed (12 buds per metre) is used while planting.
  • Dry planting and covering the setts with 1” to 2” soil cover.
  • Irrigate the fields as per the requirements.
  • Avoid partial earthing up upto 60 days.
  • Check for root borer incidence during July August. You may observe golden yellow colour of one side of the leaves or purple coloured leaves around the sugarcane field. If such symptoms are
  • observed apply 2 – 3 lt/acre Cholorpyriphos. This will help in better ratooning.
