It is reported that, the field loss in Commercial Cane Sugar (CCS) some tones 1.0 unit/ day during late crushing period i.e., March onwards. It exceeds more than that, if it is billet harvesting rather than whole stalk green cane harvesting. Generally, cane quality deterioration depends cane quality, maturity status, size of billet, atmospheric condition, harvesting practices, pest and diseases, storage methods, cut to crush delay and moisture in cane. To evaluate canes to identify sugarcane clones tolerant to post harvest cane quality deterioration, a field experiment was conducted during 2018-19 and 2019-20 at RARS, Anakapalle (ANGRAU) duly following all crop management practices with juice analysis of 24 hrs interval up to 76 hours after cane harvest. Among 15 sugarcane clones tested for their cane quality deterioration at 76 hours after harvest (76 hah), in terms of sucrose reaction was low (< 10%) in sugarcane clones 2011A 294 (0.77%) and 2011A 252 (4.43%) in January cane harvest. Correspondingly 2006A 102 (5.81 %) and 2011A 313 (5.66%) recorded less percent of cane weight loss in 76 hah. In February cane harvest sugarcane clones 2011A 262 (6.24) and 2009A 252 (3.28%) recorded less percent sucrose reaction and less cane weight loss was recorded with 2011A 262 (11.43%) and 2011A 175 (5.41%) over 76 hah. In March cane harvest, sugarcane clones 2006A 223 (5.39%), 2010A 229 (5.96 %), 2011A 319 (7.03 %) and 2011A 260 (9.61%) recorded less percent sucrose reduction and sugarcane clones 2011A 319 (7.58 %) and 87A 298 (4.42%), 2009A 252 (4.37%) recorded less cane weight loss over 76 hah over other clones tested. Cane quality deterioration in terms of percent sucrose less, percent cane weight loss was high in March month cane harvest over January & February cane harvests due to atmospheric conditions
