Abstract: A new sugarcane clone AEC81-8415, generated from seed (fuzz) of a croos combination of NCo 310 x CP56-614, imported from ARS, USDA, Canal Point, Florida, USA, alongwith other genotypes was evaluated for the stability of its performance for three economic characters at three different locations in the province of Sindh for two consecutive years. Significant (P<0.01) differences were observed in genotypes and locations x genotypes interactions for the three traits i.e. cane yield, CCS and sugar yield which indicated the presence of genetic variability amongst the genotypes and differential response of genotypes to environments. High mean performance of AEC81-8415 with 'b' values greater than 1.00 for cane and sugar yield while lesser than 1.00 for CCS (%) indicated its potential to take advantage of favourable environmental conditions for yield while unfavourable environmental conditions for quality characters.
