An experiment in sugarcane was conducted during 2021-22 to 2023-24 in strip-plot design
with three replications at Sugarcane Research Station, Vuyyuru. Sugarcane clones viz., 2012 V
67, 2012 V 123, 2013 V 126 and 2003 V 46 were tested for delayed harvesting. Significantly
more number of tillers per hectare were recorded by check variety 2003 V 46 (1,03,085) which
was statistically at par with 2012 V 67 (97,154) and 2013 V 126 (94,316) at 90, 180 and 240
days after planting. Millable canes were also significantly higher with 2003 V 46. Significantly
higher yield was recorded by 2003 V 46 (105.06 t/ha) followed by 2012 V 67 (96.42 t/ha) and
2013 V 126 (91.24 t/ha). Significantly more sucrose percent was recorded with 2003 V 46
(20.15%) which was followed by 2012 V 123 (20.05%), 2012 V 67 (19.32%) and 2013 V 126
(19.18%).The variety 2003 V 46 recorded significantly more commercial cane sugar (14.5 %)
which was statistically at par with 2012 V 123 (14.4%).The study clearly revealed that, the higher
cane yield, per cent sucrose and commercial cane sugar were obtained with check variety 2003
V 46 over other new genotypes tested in this study.
