Abstract
Five selected genetically diversified sugarcane clones were tested for yield stability for two consecutive years at six locations in Sindh. The objective of the study was to evaluate variability, effect of environmental factors and their relationship between the various quantitative and qualitative traits. Significant differences were observed between clones for all traits. Environmental interaction had significant effects on most of the traits under study. The important yield components were positively correlated at 5% level of significance. The correlation coefficients revealed that stalk weight, stalk height, number of stalks per stool and sugar percentage were the major traits contributing to cane and sugar yields. Path analysis of sugar yield exhibited maximum direct effect of cane yield followed sugar recovery.
