It is reported that, the field loss in Commercial Cane Sugar (CCS) some tonnes 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 2020-21, 2021-22 and 2022-23 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 reduction was low (< 10%) in sugarcane clones 2007A 81 (3.45%) and 2015A 137 (4.76%), 2015A 93 (6.26%) and 2015A 59 (8.69%) in January cane harvest. Correspondingly 2015A 152 (4.32%) and 2015A 59 (4.84%) recorded less percent of cane weight loss in 76 hah over other clones tested. In February cane harvest sugarcane clones 2015A 51 (6.80%), 2015A 199 (8.72 %) and 2015A 183 (15.77%) recorded less percent sucrose reduction and less cane weight loss was recorded with 2015A 233 (3.17%) and 2007A 81 (3.73%) over 76 hah of stale cane. In March cane harvest, sugarcane clones 2015A 152 (3.22%) and 2015A 222 (3.72 %) recorded less percent sucrose reduction and sugarcane clones 2015A 51 (5.72 %) and 2015A 93 (6.38 %) recorded less percent cane weight loss over 76 hah over other clones tested. Further, the percent dextran content, which is an important factor for cane quality deterioration under stale cane was recorded less percent increase in sugarcane clones 2015A 93 (34.09%), 2015 A187 (18.07%) and 2015A 230 (18.02%) during January, February and March months harvesting respectively over other clones tested at 76 hah of stale cane. Cane quality deterioration in terms of percent sucrose loss, percent cane weight loss was high in March month cane harvest over January and February months cane harvests due to prevailing atmospheric conditions
