Comparative performance of sugarcane genotypes over years and locations

The present study described the performance of a set of six elite genotypes of mid late maturity group viz, CoS 99259, Co 98016, Co 98017, CoH 110, CoH 119 and CoJ 89 (CoJ 20193) developed at UP Council of Sugarcane Research, Shahjahanpur (CoS), Sugarcane Breeding Institute, Regional Center, Karnal (Co), CCS Harayana Agricultural University, Regional Research Station, Uchani (CoH) and Punjab Agricultural University, Ludhiana (CoJ), for economic traits based on two plant crops and one ratoon crop at two locations of Punjab. The appraisal for cane yield, juice quality and ratoonability inferred high potential of CoJ 89 and CoH 119 under Punjab conditions. The comparable performance at both the locations of Punjab, viz. Sugarcane Research Farm, Ladhowal, Punjab Agricultural University, Ludhiana and its Regional Research Station, Faridkot indicated their wider adaptability. As per Annual AICRP Breeding Report, 2005, Co J 89 ranked fourth for cane yield and second for both sucrose content and CCS % at the zonal level. Owing to elite performance of CoJ 89 for cane yield and quality, it has been notified by Central Varietal Release Committee for general cultivation in NW zone comprising Haryana, Punjab, Rajasthan, Uttar Pradesh and Uttarakhand.
