Abstract
The present study aimed to assess the ratooning potential of various sugarcane strains at the Sugarcane Research Station Khanpur during the 2019-20 period. The selected promising sugarcane genotypes, including S2013-US-917, S2014-SL-1359, S2014-SL-2200, PSR-07-45, S2015-SL-89, S2015-SL-289, S2015-SL-404, S2015-SL-444, CPF-253, and HSF-240 (check), were subjected to experimentation. The research followed a Randomized Complete Block Design (RCBD) with three replications. Significant variations in ratooning performance were observed among the studied genotypes. Notably, the strain S2015-SL-444 emerged as the most promising, exhibiting the highest cane yield at 119.80 tons per hectare and excellent stubble sprouting with 1.64 sprouts per plant. Additionally, this top-performing strain demonstrated good quality, registering a field brix of 19.55%. Although the highest field brix (21.65%) was recorded in S2013-US-917, S2015-SL-89 closely followed with a field brix of 21.24%. S2015-SL-444, the standout sugarcane clone, outperformed the check by producing 14.02 tons more ratoon cane yield per hectare. Therefore, it is recommended that the genotype S2015-SL-444, with its exceptional ratooning potential, be cultivated in the agro-ecological climatic conditions of South Punjab for ratoon crop cultivation
