An investigation was carried out with eight sugarcane
genotypes along with four checks to study the phenotypic
stability of cane yield, jaggery yield and its components
under four environments. The G × E component of variation
was significant for single cane weight, number of millable
canes, commercial cane sugar percent (CCS %), cane yield,
sugar yield, jaggery yield and per cent jaggery recovery.
The genotypes, SNK 07680 and SNK 07337 were found
stable for cane yield (132.60 and 105.66 t/ha, respectively),
sugar yield (14.44 and 12.70 t/ha, respectively) its component
characters such as sucrose percentage (16.81 and 16.31,
respectively). The genotype SNK 07680 was stable for
CCS% (11.98). Genotype SNK 07658 showed adaptability
to unfavorable environment for single cane weight,
number of millable canes and sucrose percentage. SNK
07680 and SNK 07337 genotypes were stable for jaggery
recovery (10.09 and 9.60 % respectively) and jaggery yield
(13.71 t/ha and 11.44 t/ha respectively)
